Library of Congress Classification is Online

29Nov2016 at 11:33 am (Classification) ()

The other day I discovered that the Library of Congress Classification (LCC) schedules are now freely available online. Amazing!

And pretty current too. At the time of this writing these files are update as of March, 2016. If you’d like to check for newer class number additions you could also do a search on the recent LCC Approved lists.

KF Modified users without access to the KF Modified schedule can consult the PDF of the classification that KF Modified was originally based on: KF United States (General)* [pages 1-205]. You’ll also find an index in this document starting on page 551 (note that this index refers to federal and state law).

Thank you Library of Congress.

Happy cataloguing!

Class K is Now Available as Linked Data

14Apr2013 at 9:45 am (Classification) (, , )

Fantastic to learn that the Library of Congress has made class K of the Library of Congress Classification (LCC) scheme available as linked data. Kevin Ford, from the Network Development and MARC Standards Office at the Library of Congress, made the announcement on Wednesday and noted that K is likely the “largest class” bringing over two million additional resources to the collection of data found at ID.LOC.GOV.

Like the other classification schemes available at ID.LOC.GOV the K class has been released as beta. The Library of Congress “encourage[s] the submission of use cases describing how users would like to utilize the LCC data” and look forward to “working out issues with the data.”

Tina Gheen, the Emerging Technologies Librarian at the Law Library of Congress, talked about this linked data initiative last July and provides a nice overview that demonstrates the potential value of making LCC part of the Web. She also wrote about some of the challenges that come with expressing class K as linked data:

“… as any legal cataloger will tell you, Class K is full of all kinds of interesting tables needed to create a complete classification number. All these tables will need to be extrapolated into linked data as well. Semantic experts at LC have already devised a way to generate URIs and resources for the schedules and tables needed to create a classification number for the smaller classes like B and N. But duplicating that process for Class K is going to require a different level of processing power entirely. Can you feel that heat? It’s our poor servers endlessly churning away at the mountains of data and relationships buried in Class K!”

Such a great initiative and a perfect opportunity to see how we can use this to create a linked data version of KF Modified!

New Classification Schedule on Law of the Indigenous Peoples in the Americas

18Jul2011 at 1:42 pm (Classification) (, )

There is a new subclass of the Library of Congress K classification in the works dealing with the Law of the Indigenous Peoples in the Americas. The drafts were posted toward the end of June and will remain on the LC Cataloging and Acquisitions website until August 15th, 2011.

As Jolande Goldberg notes the following motivations for the development of this classification in the introduction to Class KIA-KIP,

The rising interest and marked increase in studies on contemporary indigenous law, environment, protection of cultural property and language is documented by steadily growing course offerings in U.S. and Canadian universities – as well as by inter-institutional collection development
projects that give presence and visibility to the “heritage” of Indigenous peoples. All generated great demands for bibliographic keys to the hard to find materials on a broad and varied number of subjects.

She adds, “Even LC Class KF (Law of the United States), which has a section on American Indian law and law-related materials (KF8220+), does not reflect the sovereign status and autonomy of the Indian nations, nor does it reflect current Indian law making and law developments.

Comments, suggestions and questions are welcomed by Jolande Goldberg ( at the Policy and Standards Division.
