Welcome to ITS•MARC by TLC, a leader in metadata since 1974
This page is dedicated to the catalogers who struggle every day to want to learn more and meet the ever present challenge of MORE, BETTER, FASTER, CHEAPER. If your goal is to make the library experience as rich and rewarding as it possibly can be for your library's users, then you're our kind of cataloger. We want to help. The tips below were assembled by TLC Support staff, Documentation writers, and Product Managers to help you produce the best bibliographic records in the shortest time. There's also a Shared Tips link so you can share your own discoveries. Please help us help you by suggesting ideas for this site.
Cataloger's Reference Shelf updates
The Cataloger's Reference Shelf (CRS) is a context-sensitive digital library covering the MARC standards, code lists, manuals and reference works published by the Library of Congress. The CRS helps catalogers produce high-quality cataloging records according to the MARC data standards.
The updated CRS is included in the annual BiblioFile software update. There is also a web version of CRS.
The CRS includes the following resources and manuals:
ITS•MARC Network status
Serials Limiting: If you limit a web-based search to serial formats only (in Set Limits), your search will fail in most circumstances. Until this can be resolved, avoid limiting by this format. You can remove any existing limiting by clicking the Clear Limits link.
Alternate Z39.50 server access: TLC maintains two ITS•MARC servers for Z39.50 access. The "tried and true" server (z3950.itsmarc.com) is accessed primarily by users of LS Cataloging (4.x) and by catalogers using non-TLC Z39.50 clients. The other server (z3950.library.com, the "BiblioFile" server) is used primarily by BiblioFile users. In reality, either server could be searched by any Z39.50 client with the proper attribute settings.
The following instructions may be used by BiblioFile users in the event the BiblioFile server is temporarily offline. Before making these changes, we recommend that you call TLC Support to confirm the server status and how long it might be offline.
Go into BiblioFile and select Components > Search Profile Editor. Although you can change the server a given profile uses, TLC recommends making a copy of the profile and changing the copy. Here's how:
Reporting Errors to the Library of Congress
TLC strives to maintain the most up-to-date and accurate cataloging resource data available. We rely on national libraries, professional cataloging services, and our own contributing libraries when constructing the ITS•MARC resource pool. Occasionally, even professional catalogers make mistakes.
If you find an error in a MARC record from the Library of Congress, LC wants to know about it. Please refer to http://www.loc.gov/help/contact-libarch-report.html for instructions.
