This makes interlibrary loan of these materials impossible. Other licenses state that access must be limited to the library's primary user group. It is not unreasonable for librarians to expect to provide the same access whether the resource is in print or on the web. Librarians can either accept licenses as presented and live with the consequences or reject specific objectionable terms, with the inevitable resulting delays. The analysis will then respond with things to look for in the license or clauses that should be added.
Access using passwords or IP addresses can have an effect on ease of access to web-based journals.
In some cases, publishers haven't allowed for multiple IP addresses on a single campus. Requirements such as registering each class C address have caused headaches for the librarians responsible for compiling this information. In addition, individual subscriptions aside, librarians may not fully comprehend how terms vary from publisher to publisher until they subscribe to more than one electronic journal product. For instance, one subscription may limit use by IP address to a section of campus with a maximum of 25 simultaneous users, the second subscription may limit access to users in the library building, and the third may not use IP address but instead a campus ID which has to be programmed somehow by the library. Librarians then have the challenge of clearly presenting these new services and their use restrictions to the users.
