lcsh.info

October 15, 2008

lcsh.info is a project that has been discussed in the recent past on NGC4LIB.  For a brief explanation that begins

This is an experimental service that makes the Library of Congress Subject Headings available as linked-data using the SKOS vocabulary. The goal of lcsh.info is to encourage experimentation and use of LCSH on the web with the hopes of informing a similar effort at the Library of Congress to make a continually updated version available.

as well as acess to the dataset, go here.

For a more detailed explanation about the project, see the paper Ed Summers presented at DC 2008 entitled LCSH, SKOS and Linked Data.

Bernhard Eversberg has used the dataset created by lcsh.info to help users of the database at Universitätsbibliothek Braunschweig search by authorized heading when they only know the keyword, by starting their search here.

Experimental Spanish version of LCSH

July 25, 2008

An alert just brought me news that there is a new version of lcsh-es.org LC Subject Headings in Spanish can be searched here and is described as:

This an experimental Spanish-English/English-Spanish list of subject headings. Please use it with caution! The data is not completely current a much of it has not been checked thoroughly. For more information see the Sources and About pages.

I think this source would have been helpful to students in the hispanic theology program at my former institution that couldn’t always think of the correct term to search in English.

LCSH 2008, weeks 26-28

July 22, 2008

On lower east side librarian Jenna has pulled information from Library of Congress Subject Headings Weekly Lists and added her own commentary.  For example

150 Balloon sculpture [May Subd Geog] [sp 85011322]
* 450 UF Balloon modelling
* 450 UF Balloon twisting
* 450 UF Sculpture, Balloon
* 550 BT Sculpture CANCEL
If I were a balloon artist, I might be up in arms about my art no longer being considered a form of sculpture.

Makes for some useful and entertaining reading.

AALL: The Future of Subject Access in the 21st Century

July 21, 2008

Beverly Burmeister reports on a meeting that took place at AALL.  The speakers were Barbara Tillett and Lois Mai Chan.  From the middle of the report:

For the future, Dr. Tillett predicted that the global use of LCSH will expand and that the process will be improved to reduce costs and at the same time maintain the system.

In her presentation, Dr. Chan offered her suggestions for changes to LCSH which would be theoretically sound but at the same time be more useful to OPAC and web users. 

Interesting predictions on how LCSH can be maintained yet brought in line with current trends.

 

Geocoding LCSH in the Biodiversity Heritage Library

July 16, 2008

The Code4Lib Journal published Geocoding LCSH in the Biodiversity Heritage Library in issue number 2 back in March, but for some reason my alert for LCSH just brought it up today, apparently based on a changed comment which I don’t see.  The abstract states

Reusing metadata generated through years of cataloging practice is a natural and pragmatic way of leveraging an institution’s investment in describing its resources. Using Library of Congress Subject Headings (LCSH), the Biodiversity Heritage Library generates new interfaces for browsing and navigating books in a digital library. LCSH are grouped into tag clouds and plotted on interactive maps using methods available within the Google Maps Application Programming Interface (API). Code examples are included, and issues related to these interfaces and the underlying LCSH data are examined.

One of the points I particularly liked was the importance of good cataloging data to start with.  Computers can do a lot to manipulate data, but it has to be created before it can be manipulated.
