I have been adding this information to our records for several years now. I find it very useful. We often receive boxes of materials as donations. It is much faster to scan the UPC or EAN to see if the item is in our collection than do an author/title search.
The Protocol Subcommittee of NISO Standards Committee AZ on Networked Reference Services is developing a Question/Answer Transaction Protocol (QATP) to support exchange between digital reference systems collaborating in the processing of a question. A preliminary step in the development of a protocol is to describe use cases (also known informally as "functional scenarios") that the protocol is required to support. Use cases help develop protocol requirements.

ZI-Bot (Z39.50/ISN Robot) is our project (initiated May 2001) to populate our prototype global server with ISBN and ISSN data from public Z39.50 servers around the world. Whenever a bibp/ISBN link is created and tested, ZI-Bot initiates a parallel query of approximately 75 Z39.50 servers to generate the first response. Over time, ZI-Bot will enrich the database using known item ISN queries on all Z39.50 servers.An interesting side effect is the Merged MARC data allows field by field comparison of the cataloging of the same item by different institutions. Could be useful in teaching cataloging or cataloging research. Thanks to Matthew Eberle at Library Techlog for pointing this out.
- "Lots of Copies Keep Stuff Safe As A Cooperative Archiving Solution for E-Journals" by Victoria A. Reich.
The LOCKSS model, based on analysis of the history of cultural continuity epitomized by "Lots of Copies Keeps Stuff Safe," creates low-cost, persistent digital "caches" of e-journal content housed locally at institutions that have authorized access to that content and actively choose to preserve it.
- "Building Digital Archives for Scientific Information" by Leah Solla
PRISM is a four-year project funded by Phase 2 of the Digital Libraries Initiative from the National Science Foundation to develop risk assessment strategies for web resources. It is a collaborative project between the Cornell Computer Science Department, the Human-Computer Interaction Group of the Cornell Communication Department, and Cornell University Library. Specific focus areas of the project include: digital object architecture, digital preservation, human-centered research, interoperability, policy enforcement, and web preservation.

- "The design of metadata for the Digital Museum Initiative in Taiwan" by Chao-chen Chen; Hsueh-hua Chen; Kuang-hua Chen; Jieh Hsiang.
This paper discusses issues related to the development of metadata in Taiwan. It describes the development process of a Chinese metadata system, Metadata Interchange for Chinese Information (MICI), and an XML/metadata management system, Metalogy. Both were developed under the Digital Museum Initiative sponsored by the National Science Council of Taiwan.
- "Aiming at quality and coverage combined: blending physical and virtual union catalogues" by Janifer Gatenby
This article discusses the deficiencies of search engines and the importance of metadata before examining three models of metadata retrieval: distributed; distributed data with a centralised index; and centralised union catalogue. In listing the advantages and disadvantages of the distributed model, the Z39.50 protocol is used as an example. The OAI harvest protocol is the example of the second model. Virtual union catalogues are compared with a real one. A pan-European model is discussed as a way to combine the best of all three models, with EUCAT as its base.
STMML is an XML-based markup language covering many generic aspects of scientific information. It has been developed as a re-usable core for more specific markup languages. It supports data structures, data types, metadata, scientific units and some basic components of scientific narrative. The central means of adding semantic information is through dictionaries. The specification is through an XML Schema which can be used to validate STMML documents or fragments. Many examples of the language are given.From FOS News
