Cataloging and Classification/Links

Essential Cataloging Links
General
 * Cataloging Ethics Finalizing the last draft in January 2021, the Cataloging Ethics Steering Committee released a statement of ethical principles for catalogers. The site provides the principles as well as the list of committee members and updates.
 * Cataloging Lab For catalogers who want to experiment with and propose new subject headings of classification systems, Cataloging Lab provides the space for collaboration and discussion among fellow librarians.
 * AUTOCAT is the ultimate cataloging listserv. It's very active; if you have a question about cataloging, it's almost certainly either answered in the list's archives, or answerable by one of the experienced catalogers on the list.

Library of Congress
 * Library of Congress Authorities is a searchable database of LC's Subject, Name (personal, corporate, and geographic), and Title Authority Records. This is the place to find the authorized versions of names and scope notes for subjects.
 * Library of Congress Cutter Table for LC cutters, not to be confused with...

Dewey Decimal
 * OCLC's Dewey Cutter Program, for both Cutter and Cutter-Sanborn four-figure tables. The download is free, but is only available for Windows computers.  It can be run on Linux with the Wine Windows Emulator.
 * WebDewey With an account, catalogers can look up every Dewey Decimal number and table.

RDA/MARC
 * OCLC Bibliographic Formats and Standards includes a number of standards, most importantly about the usage of each MARC field. Never heard of a 258 field?  Want to know what 1st indicator 3 in a 100 field means?  Want to see an example 300?  Look no further
 * Input Standards for Fixed-Field Elements and 006 Not sure what to do with digit 20 in a 008 field? Not sure what a DtSt is, and what its possible values mean?This is the place to find out.
 * Ending Punctuation for Variable Fields You're at the end of a 246, and you're not sure whether to end with a period, a dash, and exclamation point... This handy reference won't necessarily explain the reasons behind a particular punctuation, but will tell you which to use.
