Decomposing MARC 21 Records for Analysis

Description: This document discusses decomposing MARC 21 records for analysis. To prepare the test dataset of the 1% sample of MARC 21 records from the WorldCat database for use in the Z39.50 Interoperability Testbed, the authors need to be able to efficiently analyze the records to determine relevant records to be returned for a set of test searches. The first step in that analysis is to determine the occurrence of test search terms in specific records. This document describes the general approach for this analysis and identifies specifications for the analysis.

Procedures for Issuing Test Searches from Z-Interop Testbed Participant's Z-Client: Phase 1

Description: This document describes the procedures that participants in the Z39.50 Interoperability Testbed (Z-Interop Participant) are to use when testing Z39.50 client (Z-client) applications. The testing of a Z-Interop reference implementation Z39.50 server. Specifically, the attribute combination and other query components (e.g., Boolean operators) are reviewed, and a report of the results will be prepared for each Z-Interop participant.

Status Report to The Institute of Museum and Library Services April 1 through June 30, 2002

Description: This document provides a status report on the Z39.50 Interoperability Testbed Project (Z-Interop) covering the period of April 1, 2002 through June 30, 2002. The previous status report covered a ten-month period from May 1, 2001 through March 31, 2002. The Principal Investigator (PI) requested a no-cost extension for this project, which the Institute of Museum and Library Services approved. With the letter of approval, IMLS set a revised schedule for project status reports. Beginning July 1, 2002, status reports are due every six months. To respond to the revised schedule of status reports, this document highlights activities and accomplishments to communicate to IMLS progress on this project since the last status report.

Ten Month Status Report to The Institute of Museum and Library Services May 1, 2001 through March 31, 2002

Description: This document provides a status report on the Z39.50 Interoperability Testbed Project (Z-Interop) covering the period of May 1, 2000 through March 31, 2002. Due to a family medical emergency, the Principal Investigator was not able to complete the six-month status report that was due December 1, 2001. The Principal Investigator (PI) communicated with the Institute of Museum and Library Services (IMLS) staff about this situation, and had sent via email in November 2001 information about the progress of the project.

Indexing Guidelines to Support Z39.50 Profile Searches

Description: This document provides guidelines for indexing MARC 21 records to support a set of searches using Z39.50. The Z39.50 Interoperability Testbed Project (Z-Interop) uses these guidelines to index the 400,000 MARC 21 records that comprise the Z-Interop reference implementation of the Z39.50 server and online catalog.

Z-Interop Interoperability Testing Policies and Procedures: Phase 1 Testing

Description: This document provides an overview and the details of policies and procedures of the Z39.50 Interoperability Testbed Project (referred to as Z-Interop). Specifically, the document lays out the responsibilities and obligations of the Z-Interop testbed and the organizations that participate in interoperability testing. For purposes of this document, Z-Interop staff refers to all members of the Z39.50 Interoperability Testbed Project. Z-Interop participant refers to an individual or organization who tests its Z39.50 client or Z39.50 server through the Z39.50 Interoperability Testbed.

Data Normalization Procedures on Decomposed MARC 21 Records

Description: In this document, the authors present some aspects of data normalization of the decomposed records to improve the results of analysis. The data normalization processes use pattern-matching techniques to eliminate and/or generalize anomalous characters and terms. Since the unit of analysis in preparing the test dataset of 400,000 MARC 21 records is a "word," there was a need for data normalization to provide reliability in the subsequent analysis.

SQL Data Analysis Procedures to Create Aggregate and Candidate Record Groups on Sample of Decomposed MARC Records Phase 1 Testing

Description: This document describes the data analysis procedures developed to create the Aggregate and Candidate Record Groups using SQL statements. This is the preliminary version of these procedures tested and validated on a sample of decomposed MARC records. (For a description of how the MARC records were decomposed see the Z-Interop document, Decomposing MARC 21 Records for Analysis. A subsequent version may be necessary as the authors move to the procedures for the entire file of decomposed records.

Improving Z39.50 Interoperability: Z39.50 Profiles and Testbeds for Library Applications

Description: An operating assumption for the networked environment is that many different information systems need to interoperate for users to successfully discover and retrieve distributed resources. Meaningful interoperability is often elusive. In the library community, the Z39.50 standard protocol (ISO 23950/ANSI/NISO Z39.50) for information retrieval promised seamless and transparent networked access to library resources. Too often, the reality has not lived up to the promise. This paper discusses two efforts that offer solution paths to Z39.50 interoperability.

Mapping the Interoperability Landscape for Networked Information Retrieval

Description: This paper discusses interoperability of networked information. Interoperability is a fundamental challenge for networked information discovery and retrieval. Often treated monolithically in the literature, interoperability is multifaceted and can be analyzed into different types and levels. This paper discusses an approach to map the interoperability landscape for networked information retrieval as part of an interoperability assessment research project.

Resource Discovery Using Z39.50: Promise and Reality

Description: This paper discusses the Z39.50 protocol. The ANSI/NISO Z39.50 protocol for information retrieval addresses the complex challenges of intersystem communication. Original uses envisioned for the protocol look very little like current implementations and uses. In the 1980s, users on one library catalog system would search and retrieve bibliographic records on a remote system. By the late 1990s, there was a need for discovering networked resources and integrating access to them. Yet, the Z39.50 protocol has addressed both these scenarios. This paper provides a portrayal of Z39.50 that explains its flexibility in response to a variety of information retrieval requirements in the networked environment.

A Study of State Library Agencies' Information Technology Standards Policies and Practices

Description: This report discusses standards in state library agencies. Little is known about state library agencies' policies for standards adoption and use.
