A number of database services now offer linking to OPACs and full text journals. My understanding of the present situation is as below. Any omissions are welcome. EDINA (certain databases) - OPAC, a few full text services BIDS - full text in the ingentaJournals collection ISI Web of Science - some full text services Cambridge Scientific - some full text services WilsonWeb - OPAC Articles in hospitality and tourism - OPAC NISS Biomedical - full text in subscribed Medical/Nursing collections (as part of the HyLiFe hybrid library project Ovid set up access to our OPAC, but do not seem to have extended the facility.) OPAC linking is by ISSN. This may not always be appropriate. Linking may not be possible for all OPAC systems. Full text linking is, I think, always by IP checking so off-campus access is not possible, unless users can dial in to a university IP address. Not sure where Crossref fits into all this. There was some discussion on lis-e-journals in May, but there has been little in the way of announcements to users, apart from a press release: http://www.blackwell-science.com/crossref/live.htm. There are sample links at http://www.crossref.org/demos/gallery.htm ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Ian Winship Learning Resources, University of Northumbria at Newcastle City Campus Library, Newcastle upon Tyne NE1 8ST, UK ---------------- e-mail: [log in to unmask] phone: 0191 227 4150 fax: 0191 227 4563 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
