On Monday, June 26, at the ALA 2006 Annual Conference in New Orleans, Libbie Crawford and Joseph Miller (Director of Cataloging Services at H.W. Wilson) channeled Melvil Dewey and Minnie Earl Sears at the H.W. Wilson booth. The two answered questions about the DDC and Sears List of Subject Headings.
As you can see from the photo, Libbie lacked Melvil's distinctive beard, while Joseph lacked Minnie's distinctive hair, but their channeled alter egos convinced all watching that their systems were still relevant to libraries in the 21st century.
And, of course, the relevant Dewey numbers are 025.431 Dewey Decimal Classification, and 025.49 Controlled subject vocabularies for subject heading systems such as Sears.
