Classification

Having mentioned Dewey, LCC and the USGS classifications recently it seemed to be a good time to mention a few classification schemes. The American Physical Society publishes The Physics and Astronomy Classification Scheme.

"This Classification Scheme, on the other hand, is arranged hierarchically, by subdivision of the whole spectrum of subject matter in physics- and astronomy-related sciences into segments and then repeating the process of subdivision down to four levels. The advantages of a hierarchical scheme over the alphabetical arrangement include: like subjects can be found grouped closely together; and browsing up or down near any entry will reveal closely-related entries."

For Math, there is the Mathematics Subject Classification from the American Mathematical Society.

"(MSC) is used to categorize items covered by the two reviewing databases, Mathematical Reviews (MR) and Zentralblatt MATH (Zbl). The MSC is broken down into over 5,000 two-, three-, and five-digit classifications, each corresponding to a discipline of mathematics."

"The North American Industry Classification System (NAICS) has replaced the U.S. Standard Industrial Classification (SIC) system. NAICS will reshape the way we view our changing economy.

NAICS was developed jointly by the U.S., Canada, and Mexico to provide new comparability in statistics about business activity across North America."

Catalogs

I've found another free open-source library catalog in beta test. Here is their description:
OpenBiblio is an easy to use, open source, automated library system written in PHP containing OPAC, circulation, cataloging, and staff administration functionality. The purpose of this project is to provide a cost effective library automation solution for small schools or small public libraries.

Not Cataloging - But Good Ideas

I've come across two very good ideas recently. Walt Crawford has this proposal:

"COWLZ: the [Caucus/Coalition/Consortium/Cluster] of Online and Web-based Library-related Zines/Newsletters....

I've built a COWLZ folder in my Notes Mail space. With a little encouragement, I'd set up a COWLZ Topica list, even with the growing ad overhead of Topica-unless someone offers a no-ad list environment to help semi-organize COWLZ.

This is a call to proprietors of online and Web-based library-related zines and newsletters to do one of two things: Respond with indications of interest and the extent to which you're willing to be involved-or respond with a clear message that this is a stupid idea and you want nothing to do with it. For now, send email to me: wcc@notes.rlg.org. Include "COWLZ" beginning the subject line."

The other idea came from the latest Library Journal column Inside Track by Francine Fialkoff, a Library Most Read List to exist along side the best sellers lists.

"I've already spoken with several librarians who've said they'd participate, including Robert White at the above-mentioned Bergen County system, Julie Pringle at Fairfax County Public Library, VA, and David Domkoski at Tacoma Public Library. If you're interested, contact me at fialkoff@lj.cahners.com. As White said when we spoke, "We've failed politically to send a message to the powers that be about the clout of libraries." We must change that."

LC Classification

A new product from LC. It has a reasonable price structure and worked fairly well in the beta test.

"Great news! We are pleased to announce that Classification Web will be available as a subscription service on June 1, 2002. Subscription options, prices, and important information follow....

The Cataloging Distribution Service (CDS) will begin taking orders beginning May 1, 2002 in anticipation of the June 1 launch date. Application forms and further ordering information will be available at the CDS Web site by May 1. Check http://lcweb.loc.gov/cds/classweb.html for future product updates and application information."

Dublin Core & Open Archives Initiative

This just came in. It is good to see the convergence of various streams of work into a river of useful tools.

DCMI and OAI are pleased to announce an XML schema for unqualified DC metadata that facilitates the declaration of modular metadata components.

The Dublin Core Metadata Initiative and the Open Archives Initiative have been cooperating on metadata issues for some time. Unqualified DC metadata is the default metadata set used in the OAI Protocol for Metadata Harvesting, intended to promote cross-domain interoperability. Other, domain-specific sets are encouraged as well, as envisaged in the modular metadata framework that both communities have been striving for.

This schema has been developed for use with the OAI Protocol, and has been discussed at length in the DC-Architecture working group. It is expected that the schema will be of use for other applications as well, and will be hosted on the DCMI Website and maintained by representatives of both groups.


This development is an important landmark in the development of web-based metadata services, reflecting as it does the convergence of community consensus and the development of enabling infrastructure to support that consensus.

The schema is available at: http://dublincore.org/schemas/xmls/simpledc20020312.xsd

This and other schemas will be linked and described for readers at http://dublincore.org/schemas/

Thesaurus for Graphic Materials

I'm currently reading The Audiovisual Cataloging Current edited by Sandra K. Roe. It includes a paper giving an overview of the TGM.

"The Thesaurus for Graphic Materials I: Subject Terms (TGM I) provides a substantial body of terms for subject indexing of pictorial materials, particularly the large general collections of historical images"--I.A.

The other section of TGM is The Thesaurus for Graphic Materials II: Genre and Physical Characteristic Terms (TGM II). This section contains over 600 terms describing distinctive categories of material: an established class of pictorial types, a vantage point or method of projection, or intended purpose. Some indicate characteristics of an image's creator or a publication status or occasion. Others imply a subject but also designate a method of representation. Physical characteristic headings designate graphic materials distinguished by production processes or techniques, production stages or versions, instrument employed, markings, shape and size, and other physical aspects of graphic materials. (Adapted from the Scope and Purpose note)

Authority Records

A Handbook of Examples For Use in Authority Records Created By the NACO-Music Project by Michelle Koth provides guidance on fields 670, 667 and 675 in the MARC Authority format. Although done by the NACO-Music Project it's usefulness is not limited to music. This has been around since 1998, but I've only recently seen it. Maybe I though it was only for music.

"This handbook is a compilation of examples with explanations for creating citations for sources of information in the authority record. It does not encompass establishing the heading itself; only how to cite the sources in which information necessary to create the heading was found. The examples are not to be regarded as "rules." The fields that are affected are:

670: Source data found: includes information about the name or title represented in the 1XX field, including facts that contribute to the identification of the heading and that justify the choice of the form used as the 1XX heading and references to it.

667: Non-public general note: gives information of permanent value and general interest that is not necessarily taken from the item being cataloged.

675: Source data not found: lists consulted sources in which information about the 1XX heading might be expected to be found, but was not."--pref.

Texas Library Association Annual Conference

I'll not be at TLA this year. I'll miss seeing everybody and visiting with folks from all across Texas. Let me know how the TRGCC meeting goes. However, the LPI will have a booth there. My co-workers will be at booth 3043. Their exhibit displays a Youth Services and Children's program for public and school libraries named, "Explore! Fun with Science". Stop by the booth and tell them "Hi." Give them some good numbers to report to NASA. We have been trying for years to convince NASA that public libraries are educational institutions. All the education programs from NASA have excluded libraries and focused on the classroom. We have tried to let them know that the field of education outside the classroom is important also. They are srtarting to understand the leverage libraires have.

The Cataloging Calculator

The Cataloging Calculator by Kyle Banerjee is a very useful tool. It allows searching and display of LC Cutter, Geog. Cutter, Geog. Area Codes, Country Codes, Language Codes, AACR2 Abbrevs., and MARC Var. Fields information. It does use 3 frames, so on older machines it may be slow. Thanks Kyle, I use this often.
