The Working Group is charged with the development of some models for the delivery of commercially available indexes and content, to explicate advantages and disadvantages of each, and to describe what other institutions and consortia are doing in terms of these models. The WG should focus on citation databases (e.g. IAC or FirstSearch), ejournal collections (e.g. Elsevier or Kluwer) and other commercial resources. However the WG should keep the needs of non-commercial resources, including locally digitized collections, in mind as a factor in this evaluation. The results of this analysis should be summarized in a report to be presented at the Joint Meeting.
