Various Web directories for nursing provide listings of e-journals as well. Again, caution should be exercised in using these, as the lists often contain an unidentified mix of those that are and are not peer-reviewed. Academic and health sciences libraries provide a major means of access for those e-journals that are available by subscription only. Libraries may subscribe to individual titles from a publisher or to the publisher s entire title list. Provision may be made to allow offsite access for valid users of that institution.
Local practices vary.
Another major developing pathway for accessing scholarly journals is the set of linkages provided through major indexing services. A more common approach is for database vendors to provide links between their index entries for articles and the article full-text for journals subscribed to by a given library. PubMed provides links between index entries and freely available content. The link is typically to the abstract available at the publisher s site, although it may sometimes be to the actual full-text. Most full-text links at publisher sites, however, will require a subscription or other fee to access.
