about the Lab 4 questions
  • What do I write to help create or edit a heading?

    You’ll need to add references which confirm the heading is necessary as defined by the SACO (Subject Authority Cooperative Program) Participants’ Manual (found at this list of SACO resources).

    Eventually, with people’s edits, the heading will look like a MARC record which will be ready to submit as a proposal to LC.

  • What is the Cataloging Lab?

    Welcome to the Cataloging Lab! This is a place for catalogers and anyone who cares about library metadata to experiment with creating better controlled vocabularies. Suggesting additions and changes to the Library of Congress Subject Headings vocabulary can be an isolating endeavor—it can be difficult to determine if your heading has already been proposed or if someone else is working on a proposal at the same time you are. The Cataloging Lab is designed to be a wiki where folks can collaborate on headings together to create stronger proposals.

about NACO 1 question
  • What is NACO?

    NACO is the Name Authority Cooperative program, which coordinates the national authority file for personal, corporate, and conference names, as well as names of geographic locations, works, and expressions. The NACO program is run through PCC (the Program for Cooperative Cataloging). The great thing about NACO is that if your library is willing to support you, any library worker can become NACO trained. And, unlike the subject heading process where the Library of Congress acts as a gatekeeper, NACO contributors directly add to the authority file.

    For more information about the NACO program, including information on being trained to create name authority records, visit their website.
