Lists,
Catalogs and Portals : Models and Tools for Electronic Resource
Access Karen Calhoun, Assoc. University Librarian, Cornell Univ. In the quest to provide convenient user access to a growing number of networked electronic resources, libraries have responded in innovative ways. Access tools in use at libraries generally exist at one of three levels (although there are many variations at each level). The first level offers users Web-accessible lists, often arranged by broad subject area, of the networked databases and (sometimes) full text journals offered by the library. The second level supplements and improves upon the first by offering access to the library's networked resources via the online catalog. A third level expands users' ability to discover and connect to the library's e-resources through what have come to be called "portals." Such portals offer federated searching (the ability to search more than one database at the same time) and reference linking (the ability to link from one object to another; for example, from a citation to the full text of the article). |

Information in electronic form is seductively appealing and useful in the short term. Long term, or permanent, access will be expensive. Careful consideration of how the information is produced, what will be selected for use, and the full costs associated with selected information is essential to planning for access. Standards and careful documentation, along with non-electronic options can limit costs and extend the useful life of these records. |
