EPC Meeting 131

Giles Martin took the photo of EPC at OCLC on June 12, 2009.  Standing, from left to right: Andrea Kappler (Evansville Vanderburgh [IN] Public Library), Sandra Singh (University of British Columbia), Lyn McKinney (Billings [MT] Senior High School), and Welna van Eeden (University of South Africa); seated, from left to right: Karl Debus-López (Library of Congress, standing in for Beacher Wiggins), David Farris (Library and Archives Canada), EPC Vice-Chair Anne Robertson (Australian Committee on Cataloguing), and Deborah Rose-Lefmann (Northwestern University).

It seems like forever since I’ve written something here, and I’m suppressing the urge to report chronologically on my activities since the last time you heard from me (so stay tuned for reports on three very interesting meetings [one in Houston and two in Vienna] in which I participated back in April).  Today, I’m jumping forward to last week with a quick summary of Meeting 131 of the Decimal Classification Editorial Policy Committee (EPC), which was held June 10-12 at OCLC.  The meeting was chaired by EPC Vice-Chair Anne Robertson (Australian Committee on Cataloguing).  EPC Chair Caroline Kent (British Library) and new EPC member Jonathan Furner (UCLA [and yes, former DDC assistant editor and creator of 025.431: The Dewey blog]) were unable to attend in person, but e-mailed voluminous comments that were considered by the committee during the meeting.

EPC reviewed the full version of Table 1 (Standard Subdivisions).  One provision was postponed for discussion at Meeting 132 in November 2009: the use of T1—0286 Waste technology to represent green technology.  We'll have more to say about that issue once we sort out the ripple effects throughout the schedules.  In Table 2 (Geographic Areas, Historical Periods, Persons), EPC looked mostly to the past in reviewing provisions for the ancient world in T2—3.  Some of the ancient world proposals have implications for the modern world versions of the Mediterranean and Black Sea regions, Asia Minor, and Turkey.  EPC also approved some adjustments to German administrative units proposed by colleagues at Deutsche Nationalbibliothek, plus the placement of the Barents Sea region, North Calotte, and Sápmi (Lapland).  EPC approved the full version of Table 3 (Subdivisions for the Arts, for Individual Literatures, for Specific Literary Forms), and an expansion for Hakka (Han Chinese who speak Hakka dialect) in Table 5 (Ethnic and National Groups).

EPC approved updates in the following schedules: 004-006 Computer science, 200 Religion, 300 Social sciences, 301-307 Sociology and anthropology, 320 Political science, 330 Economics, 340 Law, 400 Language, 610 Medicine and health, 780 Music, 800 Literature, and 960 History of Africa.  EPC reviewed preliminary versions of 640 Home and family management, 690 Buildings, 710 Civic and landscape art, and 720 Architecture.  On the recommendation of EPC, we plan to post the sewing and clothing sections of 646 shortly for outside comment.  EPC also reviewed a preliminary proposal for updates to sections of 372.3-372.8 Elementary education in specific subjects.  In addition to comments from members and observers on the private EPC mailing list, EPC’s deliberations were informed by reports from the working groups associated with the European DDC Users’ Group (EDUG) in the areas of law, education, archaeology, and technical issues.

EPC reviewed several research initiatives from the OCLC Office of Research and the Dewey editorial team, plus the latest draft specification for Dewey Uniform Resource Identifiers (URIs).  We’ll be back with more information on these initiatives later.

EPC scheduled a follow-up electronic Meeting 131A (to be held August 3-28, 2009), during which the committee will address use of the term “encompassing” in the DDC, plus minor issues in 400, 710, and 780.  Meeting 132 will be held November 16-17, 2009, at the Library of Congress.

One other major Dewey event took place last week—June 12 was the last day for updating Dewey data in the current Editorial Support System (ESS).  The new ESS, along with new data formats based on the MARC classification and authority formats, is scheduled to be launched on July 5 (another reason for our recent periods of silence on this blog).  Rebecca wrote a bit about the new ESS last month—watch for more reports shortly.

Baby Animals

Spring brings news of baby animals, e.g., fawns (“Fawns Pop Up in Backyards around Washtenaw County” and “Wild Sunday II: Look Close”) or chicks (“Hatching a Love”).

Interdisciplinary works on all kinds of baby animals and comprehensive works on baby wild animals are both classed in 591.39 Young animals, a subdivision of 590 Animals.  The Relative Index entry is “Baby animals 591.39.” Examples of works classed in 591.39 are Wild Babies and Small Babies. 

Comprehensive works on baby domestic animals are classed in 636.07 Young of animals, a subdivision of 636 Animal husbandry.  The Relative Index entry is “Baby animals—domestic animals 636.07.”  An example of a work classed in 636.07 is Animal Babies on the Farm.

Works on fawns are classed in 599.65139 Fawns, a built number to which the LCSH “Fawns” has been editorially mapped in WebDewey.  The number 599.65139 Fawns is built with 599.65 Cervidae (Deer) plus 1 General topics of natural history of animals from the add table at 592–599 Specific taxonomic groups of animals, following the footnote add instruction at 599.65, plus 39 from 591.39 Young animals, following add instruction at 1 General topics of natural history of animals in the add table at 592–599. An example of a work classed in 599.65139 is Fawns.

Works on baby chickens are classed in 636.507 Chicks, a number built with 636.5 Poultry    Chickens plus 0 plus 7 from 636.07 Young of animals, following add instruction at 636.5001–636.508 Standard subdivisions, specific topics of husbandry of poultry.  An example of a work classed in 636.507 Chicks is A Chick Grows Up.

Diabetes Type 1 and 2

In addition to clarifying the scope of pediatrics and adolescent medicine, the May 2009 posting of New and Changed Entries presents two new numbers, subdivisions of 616.462 *Diabetes mellitus:

616.462 2            *Diabetes mellitus, type 1 (Insulin-dependent diabetes)

616.462 4            *Diabetes mellitus, type 2 (Non-insulin-dependent diabetes)

*Add as instructed under 616.1–616.9

An example of the kind of work that will be classed in 616.4622 Diabetes mellitus, type 1 (Insulin-dependent diabetes) is Type 1 Diabetes in Adults: Principles and Practice.  Incidentally, the LCSH (Library of Congress Subject Heading) “Diabetes” is used for comprehensive works on type 1 and type 2 diabetes and is also used for type 1 diabetes alone.  The MeSH (Medical Subject Headings) heading is “Diabetes Mellitus, Type 1.”

An example of the kind of work that will be classed in 616.4624 Diabetes mellitus, type 2 (Non-insulin-dependent diabetes) is The Type 2 Diabetes Sourcebook.  The LCSH “Non-insulin-dependent diabetes” is used for type 2 diabetes.  The MeSH heading is “Diabetes Mellitus, Type 2.”

Pediatrics and Adolescent Medicine

In a March 2008 blog entry the Dewey editorial team and the Decimal Classification Editorial Policy Committee (EPC) sought advice about treatment of pediatrics and adolescent medicine in DDC.  Here is an excerpt from the blog:

The scope of 618.92 Pediatrics is defined by the first three notes in the entry:

Medicine for infants and children up to puberty

Class here comprehensive works on child and adolescent medicine

For medicine for young people who have reached puberty, see 616.00835

The problem is that many other definitions of the scope of pediatrics include young people past puberty.

. . . . .

Is the broader definition of pediatrics that includes adolescents widespread in the world? Should we broaden the scope of 618.92 Pediatrics to match?

Responses were mixed.  In the end the decision was to retain the current definition of pediatrics in DDC and provide additional schedule entries, notes, and Relative Index entries to clarify how works on pediatrics and adolescent medicine should be classed.  The May 2009 posting of New and Changed Entries presents the material added to clarify the scope of pediatrics and adolescent medicine. 

Here is a brief guide to classifying works on pediatrics and adolescent medicine.  Works on (1) medicine for infants and children up to puberty and (2) comprehensive works on child and adolescent medicine are both classed in 618.92 Pediatrics.  An example of a work classed in 618.92 Pediatrics is Practical Guide to the Care of the Pediatric Patient. 

Works limited to adolescent medicine are classed in 616.00835, a number built with 616 Diseases plus standard subdivision T1—0835 Young people twelve to twenty.  The extra zero comes from following the pattern at 616.008 History and description with respect to kinds of persons. With the May 2009 posting, the built number 616.00835 has an entry in the schedule, with notes:

616.008 35    Young people twelve to twenty

Do not use for diseases of young people twelve to twenty who have not reached puberty; class in 618.92

Class here adolescent medicine

An example of a work classed in 616.00835 is Adolescent Health Care: A Practical Guide.

Works on a specific disease or branch of medicine are classed in subdivisions of 618.92 Pediatrics if they cover (1) infants and children up to puberty or (2) both children and adolescents.  For example, works on cancer in children, or on cancer in children and adolescents, are classed in 618.92994 Pediatric cancer, a built number with the Relative Index entry “Cancer—humans—pediatrics.”  The number 618.92994 is built with 618.92 Pediatrics plus 994 from 616.994 Cancers, following instructions under 618.921–618.929 Specific diseases.  An example of a work classed in 618.92994 is Pediatric Oncology.

Works on a specific disease or branch of medicine are classed with the disease or branch in 610 Medicine and health if limited in coverage to adolescents.  If the topic approximates the whole of the number, the standard subdivision T1—0835 Young people twelve to twenty is added.  For example, works on cancer in adolescents are classed in 616.99400835 Cancer in young people twelve to twenty, a built number with the Relative Index entry “Cancer—humans—adolescent medicine.”  The number is built with 616.994 Cancers plus T1—0835 Young people twelve to twenty, following the footnote instruction at 616.994 to “Add as instructed under 618.1–618.8.”   The extra zero comes from following the pattern for standard subdivision notation 00835 Young people twelve to twenty given in the add table under 618.1–618.8 Gynecology and obstetrics.  (Why does the footnote at 616.994 Cancers instruct one to add from 618.1–618.8 instead of 616.1–616.9?  Because that is a convenient way to provide for the full range of treatments needed for cancer: the add table at 616.1–616.9 does not provide for surgery as a treatment and the add table at 618.1–618.8 does.)  An example of a work classed in 616.99400835 is Cancer and the Adolescent.

2009 Influenza A (H1N1) (Swine Flu)

The 2009 Influenza A (H1N1) (Swine Flu) has been in the news, e.g., “Swine Flu” and “WHO Says H1N1 Flu Cases, Death Toll Rise.”  Informative web sites have appeared, e.g., 2009 H1N1 Flu (Swine Flu).

In a May 2006 blog entitled “Bird Flu,” we made several points about DDC treatment of influenza A (H5N1) that apply also to DDC treatment of 2009 Influenza A (H1N1).  The key point is that “the DDC medicine schedule does not make fine distinctions based on the type of virus nor on the origin of the virus; rather, it treats all influenza in a particular animal the same.”  The comprehensive number in medicine for influenza in humans (the number with the Relative Index entry “Influenza—medicine”) is 616.203 Influenza.  That is true regardless of what kind of virus causes the influenza.  An example of a work classed in 616.203 is Influenza.

Works discussing details about one or more types or subtypes of viruses that cause influenza in humans are classed in 616.203019 Medical virology of influenza (built with 616.203 Influenza plus notation 019 Medical virology from the add table under 616.1–616.9 Specific diseases, following the footnote instruction at 616.203, “Add as instructed under 616.1–616.9”).  An example of a work classed in 616.203019 is Influenza Virology: Current Topics. 

Works about use of drugs to treat influenza in humans are classed in 616.203061 Drug therapy for influenza (built with 616.203 Influenza plus notation 061 Drug therapy from the add table under 616.1–616.9 Specific diseases, following the footnote instruction, “Add as instructed under 616.1–616.9”).  An example of a work classed in 616.203061 is Zanamivir for the Treatment of Influenza in Adults: A Systematic Review and Economic Evaluation.

Incidence of influenza in humans and vaccination to prevent influenza in humans are both classed in 614.518 Influenza.  How does one know?  The first clue is obvious: the Relative Index entry “Influenza—incidence” leads to 614.518.   The second clue is more subtle.  The Relative Index entry “Vaccination—disease control” leads to 614.47 Immunization, which has the note: “Class here vaccination.”  Above 614.47 in the hierarchy, at 614.4 Incidence of and public measures to prevent disease, is the see reference: “For incidence of and public measures to prevent specific diseases and kinds of diseases, see 614.5.”  The see reference has hierarchical force; consequently, works on immunization for a specific disease are classed with the disease under 614.5 Incidence of and public measures to prevent specific diseases and kinds of diseases.  There are also other clues.  If one follows the Relative Index entry “Vaccines—pharmacology” to 615.372 Vaccines, one finds the class-elsewhere note: “Class use of specific vaccines with the disease in 614.5, e.g., use of influenza vaccines 614.518.” If one looks at the add table under 616.1-616.9 Specific diseases and considers using notation 05 Preventive measures, one finds the class-elsewhere note: “Class public measures for preventing a specific disease, use of specific vaccines with the disease in 614.5, e.g., mosquito control for prevention of malaria 614.532, use of influenza vaccines 614.518.” Examples of works classed in 614.518 Influenza are Global Spread of the Avian Flu: Issues and Actions and Immunization Safety Review: Influenza Vaccines and Neurological Complications.

Comprehensive works on drug therapy and vaccination for influenza in humans are classed in 616.203061 Drug therapy for influenza.  How does one know?  The first indication is the Relative Index entry that marks 616.203 as the comprehensive number in medicine for influenza: “Influenza—medicine.”  Second, see references mark 616+ as logically superordinate to 614.5+.  At 616 Diseases is a see reference to 614.4: “For incidence of and public measures to prevent disease, see 614.4.”  The see reference implies that 614.4 is logically a subdivision of 616.  The see reference from 614.4 to 614.5 quoted above similarly indicates that 614.5 is logically a subdivision of 614.4.  In other words, 616 is superordinate to 614.4, which in turn is superordinate to 614.5.  Because see references have hierarchical force, what is true of 616 is also true of 616.203061.  Because of the hierarchical relationships marked by see references, the first-of-two rule does not apply to a choice between 614.518 and 616.203061.  An example of a work classed in 616.203061 is Combating the Threat of Pandemic Influenza: Drug Discovery Approaches.

Cattle Genome

The cattle genome has been in the news recently, e.g., “Cattle Genome Sequenced” and “Bovine Genome Could Lead To Better Meat For Consumers, Experts Say.” A quotation from the latter article:  “The researchers used the complete sequence from a single Hereford cow and comparative genome sequences for six more breeds, looking for changes called single nucleotide polymorphisms – SNPs – markers that can help researchers identify favorable traits.” Related papers include “Genetics: It's a Bull's Market,” “The Genome Sequence of Taurine Cattle: A Window to Ruminant Biology and Evolution,” “Genome-Wide Survey of SNP Variation Uncovers the Genetic Structure of Cattle Breeds” (all in Science), and “A Whole-Genome Assembly of the Domestic Cow, Bos Taurus” in Genome Biology.  There is also a special series from BioMedCentral: Bovine: The Companion Papers for the Publication of the Bovine Genome Sequence.

Where might one begin looking for DDC numbers for the cattle genome?  One might browse the Relative Index in WebDewey for “cattle”:

Cattle       636.2
Cattle—agricultural economics       338.1762
Cattle—animal husbandry       636.2
. . . . .
Cattle—zoology       599.6422

The number opposite the unsubdivided entry for cattle is both the interdisciplinary number for cattle and the animal husbandry number for cattle: 636.2 Ruminants and Camelidae    Bovidae    Cattle.  The record for the zoology number for cattle—599.6422 Bos (Oxen)—has the note: “Class interdisciplinary works on Bos taurus (domestic cattle) in 636.2.”  Clearly 636.2 is a good number for works that emphasize domestic cattle, including interdisciplinary works that have some discussion about wild ancestors of domestic cattle.

One might also browse the Relative Index for “genetics”:

Genetics       576.5
Genetics
      see Manual at  576.5 vs. 572.8         
Genetics—animal husbandry       636.0821
Genetics—animal husbandry—sheep       636.30821
Genetics—animals       591.35
. . . . . .

Although the interdisciplinary number for genetics is in biology (576.5 Genetics), the comprehensive number for genetics in animal husbandry is 636.0821 Genetics.

In biology there is a split between the interdisciplinary number 576.5 Genetics and 572.8 Biochemical genetics.  The distinction is explained in the Manual entry 576.5 vs. 572.8 Genetics vs. Biochemical genetics.  Genomes are classed with biochemical genetics in 572.86 DNA (Deoxyribonucleic acid), where there is a note: “Class here chromosomal DNA, codons, genes, genomes.”  For example, works on genomes of sponges are classed in 572.86134 DNA of sponges.  The number is built with 572.86 DNA (Deoxyribonucleic acid) plus 1 from 571.1 Animals, as instructed under 572.5–572.8 Specific biochemicals and biochemical genetics, plus 34 from 593.4 Porifera (Sponges) as instructed at 571.1.  An example of a work classed in 572.86134 is Genome Organization in Sponges. 

In animal husbandry, general genetics and biochemical genetics are classed together in 636.0821 Genetics or in other subdivisions of 636 Animal husbandry.  Examples of works classed in 636.0821 are Chromosome Mapping of Some Genes in Farm Animals by In Situ Hybridization and Genome Analysis in Domestic Animals.

According to the rule of zero, for works about genetics of cattle, 636.2 Ruminants and Camelidae    Bovidae    Cattle is preferred over 636.0821 Genetics.  The heading at 636.2 is a dual heading—actually, a triple heading, with three parts. Further addition is possible for each of the three parts, even the smallest part, cattle. The information conveyed in the dual/triple heading has hierarchical force and carries down to subdivisions that may mention only the broadest part of the heading as a kind of shorthand. At 636.2001–636.208 Standard subdivisions, specific topics on husbandry of ruminants and Camelidae is a note that permits addition of notation for genetics to the number for cattle:  “Add to base number 636.20 the numbers following 636.0 in 636.001–636.08, e.g., heifers 636.207 . . . . .”  Thus one can add 821 from 636.0821 Genetics to 636.20  to build 636.20821 Genetics of ruminants and Camelidae, of Bovidae, of cattle.  An example of a work classed in 636.20821 is The Bovine Gene Map.

What about the genome sequence of a single Hereford cow?  Hereford cattle are classed in 636.222 English beef breeds, where there is a note: “Including Hereford and Shorthorn cattle.”  Again by the rule of zero, for works about genetics of Hereford cattle, 636.222 is preferred over 636.20821.  There are no instructions for adding to express genetics of specific breeds, and if there were, one could not use them for Hereford cattle because Herefords are in the including note.  An example of a work classed in 636.222 is International Genetic Evaluation for the North American Hereford and Polled Hereford Populations.

Presidential Pets

Many U.S. presidents and their families have had well-known pets, as can be seen in the photo essay “Presidential Pets.”  Works about presidential pets are often historical and biographical, e.g., The Presidents and Their Pets, which is classed in 973.099 United States presidents—collected biography (built with 9 plus T2—73 United States plus 099 Collected persons treatment, as instructed under 930–990 History of ancient world; of specific continents, countries, localities; of extraterrestrial worlds and under 973.01–973.09 Standard subdivisions, which shows that only one zero instead of two should be used and which has the note, “As modified under 930–990”).  

There are also historical and biographical works about individual pets, e.g., First Dog, Fala, which is classed in 973.917092 Administration of Franklin Delano Roosevelt, 1933–1945—biography (built with 973.917 Administration of Franklin Delano Roosevelt, 1933–1945 plus T1—092 Persons). Even Millie’s Book: As Dictated to Barbara Bush sticks close to history and biography; the book is classed in 973.928092 Administration of George Bush, 1989–1993—biography (built with 973.928 Administration of George Bush, 1989–1993 plus T1—092 Persons).       

Biographical works about presidential pets are usually classed according to the advice in the “Families and close associates of the famous” part of the Manual note at T1—092 Persons: “Class a history of the immediate or extended family of a famous person with the biography of that person if the work strongly emphasizes the famous person. The same rule applies to the biography of a single relative or close associate of a famous person. However, if the relative or associate is important in his or her own right, or if the famous person is not strongly featured, class the life of the relative in the subject warranted by his or her own work, e.g., use 269.2092 for a biography of evangelist Ruth Carter Stapleton, sister of President Jimmy Carter, that treats the president only incidentally.”  Most presidential pets are not famous or important in their own right—that is, they are best known as pets of famous people, not best known as prize-winning show dogs or racehorses, not famous for having rescued humans, etc.—and usually the famous person is strongly featured.  Consequently, biographical works about presidential pets are usually classed in presidential biography numbers instead of in the pets’ own biography numbers, and T1—0929 Persons treatment of nonhumans is not used.

The newest presidential pet, Bo, is a Portuguese water dog.  The interdisciplinary number for the Portuguese water dog is 636.73 Working and herding dogs, where the breed is named in the including note and where there is an unsubdivided Relative Index entry for the breed.  The American Kennel Club puts the Portuguese water dog in the “working group.”  The Manual entry 636.72–636.75 Specific breeds and groups of dogs explains, “The main groupings used are those recognized by the American Kennel Club (AKC) in The Complete Dog Book, 1997. The roughly corresponding groupings of the Kennel Club of United Kingdom (KC) are given in class-here notes when the names differ materially.”  An example of a work classed in 636.73 Working and herding dogs is Portuguese Water Dog.  

Biofilms

“Scientists Learning to Target Bacteria Where They Live,” an article in Washington Post by Kari Lydersen, recently drew attention to bacterial biofilms:

In the arms race between humans and bacteria, the ability to form “biofilms”—large aggregations of microbes embedded in a slimy matrix—has been one of the weapons the organisms use to defeat the immune system, antibiotic drugs and other threats. But scientists, who only recently recognized the role that biofilms play in antibiotic resistance, may be closing in on promising prospects for defeating pathogens.

Scientists have learned that bacteria that are vulnerable when floating around as individual cells in what is known as their “planktonic state” are much tougher to combat once they get established in a suitable place—whether the hull of a ship or inside the lungs—and come together in tightly bound biofilms. In that state, they can activate mechanisms like tiny pumps to expel antibiotics, share genes that confer protection against drugs, slow down their metabolism or become dormant, making them harder to kill.

The answer, say researchers, is to find substances that will break up biofilms.

Interdisciplinary works on microbial biofilms are classed in 579.1782 Ecological communities of microorganisms, fungi, algae (built with 579.17 Ecology, organisms characteristic of specific environments plus 82 from 577.82 Ecological communities, according to instructions at 579.171–579.178 Specific topics in ecology, specific environments).  The number 579.1782 is a subdivision of the interdisciplinary number for microbiology: 579 Microorganisms, fungi, algae.  The number 579 has the note “Class here microbiology” and the unsubdivided Relative Index entry “Microbiology.”  An example of a work classed in 579.1782 is Community Structure and Co-operation in Biofilms.

Interdisciplinary works on bacterial biofilms are classed in 579.31782 Ecological communities of prokaryotes (built with 579.3 Prokaryotes, which has the notes: “Variant names: Monera, Schizomycetes, Schizophyta, bacteria” and “Class here bacteriology,” plus 17 from 579.17 Ecology, organisms characteristic of specific environments, following the footnote instruction at 579.3 to add as instructed under 579.2–579.8 Specific taxonomic groups of microorganisms, fungi, algae, plus 82 from 577.82 Ecological communities).

Comprehensive medical works on microbial biofilms are classed in the comprehensive number for medical microbiology:  616.9041 Medical microbiology.  The number 616.9041 has the Relative Index entry “Microbiology—medicine.”  Under 616.9041 is the note: “Class here drug resistance in microorganisms.”   The number was built with 616.904 Special topics of communicable diseases plus 1 from 01 Medical microbiology in the add table under 616.1–616.9 Specific diseases according to instructions under 616.904.  An example of a work classed in 616.9041 is Biofilms, Infection, and Antimicrobial Therapy.

Under 616.9041 Medical microbiology is the note:  “Class medical microbiology of a specific disease or group of diseases with the disease or group of diseases, plus notation 01 from table under 616.1-616.9, e.g., medical microbiology of tuberculosis 616.99501.”     Comprehensive medical works on bacterial biofilms are classed in 616.9201 Medical microbiology of bacterial diseases (built with 616.92 Bacterial diseases plus 01 Medical microbiology from table under 616.1–616.9 Specific diseases, following footnote instruction at 616.92 to add as instructed under 616.1–616.9).  An example of a work on bacterial biofilms classed in 616.9201 is Control of Biofilm Infections by Signal Manipulation.   

Rethinking Meals

The current development for meals at 641.52–641.54 Cooking specific meals combines the type of meal with the time of day consumed.  This approach poses a problem for the representation of the main meal of the day in different cultural contexts.  We are proposing a simpler framework for meals to meet the needs of the worldwide community of Dewey users.  We welcome comments and suggestions--please tell us what you think!  Please reply directly to this blog entry (or alternatively to dewey@loc.gov) by March 27, 2009.

Proposed Development for Meals 

>                                   641.52–641.54       *‡Cooking specific meals

                    Class comprehensive works in 641.5

 

641.52          First meal of the day

 

Class here breakfasts, brunches

 

641.53  *‡     Light meals

Class here dinners, lunches, suppers, teas as main meals

 

Class breakfasts and brunches in 641.52; class dinners, lunches, suppers, teas as light meals in 641.53

 

Comprehensive works on specific meals will continue to be classed in 641.5 Cooking, where there are further instructions about the choice of numbers within 641.5 and elsewhere in 641 Food and drink and 642 Meals and table service.  For example, works on cooking specific kinds of dishes associated with specific meals are classed in 641.8 Cooking specific kinds of dishes, preparing beverages, e.g., wraps are classed in 641.84 Sandwiches.

Below are the proposed changes to the current development to produce the new framework shown above.  Changes to schedule numbers are indicated only by underlining.  Other changes are underlined, and deletions are marked by strikethroughs.

Two Museums

Two Museums

Currently I’m on vacation in Australia, being a tourist in my original home. Over the last few days I’ve visited two museums in the Sydney area, one well-known and one less known.

The Powerhouse Museum is very popular – when I was there, it was full of young children looking at the special Star Wars exhibit.  Its history goes back to the 19^th century, but it opened on its present site (the former Ultimo Power Station) with its current name in 1988.  My favourite item in its collection is the destination board from Sydney's Central Railway Station, with the names evoking railway lines and stations throughout New South Wales (many now closed to passenger traffic).

The Powerhouse describes itself as “science + design” but the best Dewey category for it is 600 Technology (Applied sciences), so that the Dewey number for the museum would be 607.349441.  That number is an irregular use of standard subdivisions: you start with 607.3 Other aspects of education and research, then add notation 4 from -074 Museums, collections, exhibits in Table 1 (following the instructions at 607.3), then add -9441 Sydney metropolitan district from Table 2 (following the instructions at -74 in Table 1).

Less well-known is the Museum of Fire in Penrith, about 50 kilometres west of Sydney.  (I was the only visitor there on a Saturday afternoon.)  This is devoted to the history of fire fighting, and has a large collection of fire engines and other fire-fighting equipment.

In Dewey, the interdisciplinary number for fire fighting is 628.925 Fire fighting technology, so the Dewey number for the Museum of Fire would be 628.9250749441.  This is a regular standard subdivision, built by adding -074 Museums, collections, exhibits from Table 1 to the base number 628.925, then adding -9441 Sydney metropolitan district from Table 2.  (Penrith is in the including note at -9441 in Table 2.)
