A wealth of useful resources here, including DDC tools, converters and calculators, RDA resources, many more.

I have saved my presentation as both PPT so you can see the notes, and PDF in case you have trouble viewing the PPT.

Both Erica and I added a little extra information based on the discussion at our presentations.

In case you missed the update from the Dewey Blog (or ignored it because there were no pretty pictures)…There are new icons appearing in the WebDewey search results.

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.)

Thanks to A Portal to my Cataloging Aids and the Dewey Blog

As the tagline of the blog states “Everything you always wanted to know about the Dewey Decimal Classification® system but were afraid to ask…” is exactly what 025.431 : The Dewey blog aims to do. Articles touch on current topics of interest and how to build/select the correct Dewey number.

An overview what updates are available is here. New and changed entries are available as PDF or Word documents here and you can subscribe via RSS to various Dewey updates here.

Ever find yourself with a perfectly good classification number in Library of Congress but your library uses Dewey?  Or vice versa?

If you don’t have access to Mona L. Scott’s three volume Conversion Tables, then QuestionPoint might be able to help you.  QuestionPoint does use the National Library of Medicine (NLM) Classification number for medical topics.

LCC to Dewey
– Mapping to LCC Schedules D, J and K are in process. Instead of Schedule R, NLM’s QS-QZ and W schedules are used.

Dewey to LCC
-Since QuestionPoint uses NLM for Schedule R, most NLM classes map to 362.1-362.3, and 610-618.97

More information on NLM classification, including the schedules.
