Library of Congress Changed Subject Heading Subdivisions

Sept. 1 there will be a new edition of the Library of Congress Changed Subject Heading Subdivisions.

Each August I review the previous years' changes from Library of Congress's "Weekly List" of new headings and cross-check them with their annual "Free-Floating Subdivisions". Questionable entries are referred to the Library of Congress Cataloging Distribution Service for resolution. Changes are then added to my master file, which is then totally cumulated. Official publication date of each year's new edition is September 1.

Joyce T. Ogden, the author, sent me a very nice note asking that I announce the newest version of her work.

British Library Catalog

Image via WikipediaThe British Library has made their catalog freely available for research.

As part of its work to open its metadata to wider use beyond the traditional library community, the British Library is making copies of its main catalogue and British National Bibliography datasets available for research purposes. Files are initially being made available in XML and structured in an RDF/DC format (see sample). Files are distributed under a Creative Commons Attribution-NonCommercial-ShareAlike 3.0 Unported License.
The British Library is currently investigating options for structuring its catalogue information as linked data and is collaborating with a number of organisations in examining the issues associated with making bibliographic metadata available in this way.
