While there are a lot of library-related blogs, Technical Services people have been slower to get into the biblioblogosphere.
On the cataglogers pages of the CMRLS website, I have a list of Cataloging Blogs which I've just updated with several more. Here's a little information about the new additions. Most have begun in the last 6 months.
A Portal to My Cataloging Aids Website is written by Lynne LeGrow who says "For many years I have maintained a website with cataloguing aids, reminders, and links." Her list of aids is similar to my cataloging pages mentioned above. Lynne is the Cataloguer (note the u) at the Halifax Public Library in Nova Scotia.
Celeripedean claims to be "Just Another Blog About Libraries." The author is Jennifer Eustis who "would like to share my thoughts on librarianship and cataloging." Jennifer is Catalog & Metadata Librarian at the Snell Library at Northeastern University in Boston.
From the Catalog of Babes describes the day-to-day adventures of recently graduated librarian Rachel Clarke (therefore just a "babe in the woods") who is now the cataloger in a library of the Fashion Institute of Design and Merchandising in California.
Future4Catalogers Blog is written by Heidi Hoerman, faculty member of the School of Library and Information Science at the University of South Carolina, as she "tries to understand what's coming." Heidi made the cataloging headlines in October of 2008 when she announced at the OLAC/MOUG conference in Cleveland that she thought RDA would die a slow death. She's since recanted.
Inquiring Librarian is the blog of Jenn Riley. Jenn is Metadata Librarian with the Indiana University Digital Library Program. I had the pleasure of attending one of Jenn's programs on Metadata at the OLAC/MOUG conference in Cleveland.
Metadata Librarian Experience is written by Jin Xiu Guo who is the Assistant Librarian, Catalog/Metadata Librarian at Washington College in Chestertown, Maryland.
I'm not certain if Resource Description and Access: ALA Rep Notes is still being updated, but it offers lots of insight into the RDA process. RDA is due to be released in November 2009. The ALA Rep is John Attig, of Pennsylvania State University.
I like the witty title Three Catalogers Walk Into a Blog. The three catalogers are Jennifer B. Young, Serials Cataloger at Northwestern University; Joy Anhalt, Technical Services Manager at the Tinley Park Public Library, Tinley Park, Illinois; and Richard A. Stewart,Senior Cataloger at the Indian Trails Public Library Disctrict and an instructor in the Graduate School (formerly the Graduate School, USDA). While this blog has been around since September 2008, I just discoverd it recently.
These are all good blogs to add to your RSS feed. If, after a while, you don't find them particularly useful, it's easy enough to delete the feed. I find a lot of the cataloging blogs cover the same information, so a review of them can often be very quick.
