WebDewey 2.0 users, be ready for a nice surprise when you log in today. We have introduced some major enhancements plus cosmetic improvements that we hope will delight and excite you as much as they do the Dewey team. Over the next few days we’ll be discussing the variety of improvements and new features that you’ll find in the system, but let’s start today with the two big ones, 1) the history of numbers and 2) improved identification of built numbers and Manual notes.
We have had the history of numbers codified in our internal DDC data files going back to DDC 20 (1989), but we have never had a way to make this deep historical information routinely available to users until now. Starting today, WebDewey users will be able to access the contents of any MARC 21 685 History Note field associated with a particular class by clicking on arrow in the right-hand corner of the History box on the record display page. For example, look at the class record for 005.3. If you open the History box (click on the arrow in the right-hand corner of the box), you’ll see the following information:
General purpose application programs relocated to 005.5
2003, Edition 22
(We reformatted the underlying MARC 21 representation to make it more readable; in our internal database, we have the following version of the same information coded in a 685 field: 685 20 $t General purpose application programs $i relocated to $a 005.5 $d 2003 $2 22 $9 ess=685.)
If you click on the link to 005.5, that link will take you directly to the record display for 005.5. Open the History box and you will find additional information about the history of 005.5:
formerly located in 005.3
2003, Edition 22
Specific programs with interdisciplinary applications formerly located in 005.3042
2003, Edition 22
There’s one other major change in today’s installation: the inclusion of new icons to identify built numbers and Manual notes. Built numbers are represented by a puzzle piece icon; Manual notes are represented by a book icon. Both types of icons are included in search results. For example, the search results for a search on 005.3 include the Manual note 005.3 (identified with the book icon) and the built number 005.3742 (identified with the puzzle piece icon). The puzzle piece icon also is used to identify built numbers in browse results. On the individual record display screen, the Manual icon appears next to the number and caption for the Manual note (for example, look at the Manual note for 005.3). In hierarchical displays for built numbers, the puzzle piece icon can appear anywhere in the hierarchical display for the number. For example, display the record for 338.47004 Computer industry. In the hierarchical display, the built number icon appears next to 338.47004, and also next to two built numbers in the downward hierarchy, 338.4700411 and 338.470046. (If you don’t see the icons associated with the aforementioned examples, it may be because relevant information has been cached in your browser. If you want to see the icons immediately and do not want to wait until the cache is refreshed, you can press <ctrl> + <F5> inside a WebDewey screen associated with one of the examples, which will cause your browser to reload the cached information.)
We’d love to hear from WebDewey users about the usefulness of these new features. We’re especially interested in learning more about how you might make use of the history information.
Stay tuned for more information about recent and planned improvements to WebDewey!
