Understanding MARC Bibliographic
http://www.loc.gov/marc/umb/
When I first started copy-cataloging, the only resources I had were a copy of Understanding MARC
Bibligraphic and a MARC flip chart from Follett. Understanding MARC
Bibliographic is still the best introduction to MARC that I've seen [Charles].

ABLE Dewey Tutorial
http://www.lili.org/forlibs/ce/able/course7/01index.htm
This online tutorial is based on the 13th edition of the Abridged Dewey Decimal Classification.
Unfortunately, the tutorial refers to specific page numbers in the 13th edition -- page numbers that
don't match the 14th ed. Even though the tutorial needs to be updated, it is still possible to follow
along and get an introduction to the structure of the DDC and how to build numbers. Contact the IMC
to borrow a copy of the 14th edition.

DeweyBrowser

Based on the 14th edition of the Abridged Dewey Decimal System. Does not include tables, manual,
or notes of the printed Abridged Dewey. A quick way to confirm a Dewey number or explore the Dewey Decimal System.

http://listserv.acsu.buffalo.edu/archives/autocat.html
This is a fairly active list -- 20 or messages a day, so if you miss a few days, the messages pile up.
If you're really interested in cataloging, this listserv is a must. It covers a wide range of cataloging
and classification issues, both theory and practical aspects. Sometimes vigorous discussions on things
only catalogers could care about, such as use of the serial comma, or the proper spelling of the word
catalog (vs. catalogue).

the news and explain where it would be classed in Dewey and why. There are usually three or four posts a week.
