A subcommittee of the Digital Library Federation’s Electronic Resource Management Initiative, Phase II has released White Paper on Interoperability between Acquisitions Modules of Integrated Library Systems and Electronic Resource Management Systems.
Here's an excerpt from the "Executive Summary":
The following white paper investigates interoperability between the acquisitions modules of integrated library systems (ILS) and electronic resource management systems (ERMS). The first section of the paper features four case studies: UCLA, Cornell University, the Tri-College Consortium of Bryn Mawr, Haverford, & Swarthmore Colleges, and the Library of Congress. Each case highlights the library’s institutional environment, consortium considerations, systems architecture (ILS, ERMS, and link resolver), and electronic resource workflows. . . .
The second part of the paper reports on conversations held with product managers and other relevant staff of the leading ERMS. . . .
The paper concludes with a recap of the general value of ILS/ERMS interoperability and some of the more significant barriers to achieving it. Finally, it is proposed that further discussions among stakeholders take place, and that these discussions focus on establishing agreement on a small set of elements for exchange and on the development of standard identifiers.
