    Abstract
    Academic libraries today are faced with the prospect of numerous alternatives to traditional printed indexes to the primary literature. Not only are many indexes made available by publishers on CD-ROM products, but most of these products can be acquired on computer tape for local mounting. This happy situation is further augmented by the availability of these products through mediated search services such as Dialog and end user services such as OCLC FirstSearch. Choosing the best alternative becomes a matter of estimating demand and comparing costs for each type of access. These estimates are complicated by lack of information on how often patrons will use a given alternative and by lack of qualitative data. Results of comparisons made at Trinity and Clemson Universities provide some revealing benchmarks that can help to place a quantitative framework around the decision process

    Abstract
    In the field of electronic publishing, encyclopedias represent a unique sort of text for investigating advanced methods of navigation. The user of an electronic excyclopedia normally expects special methods for accessing the entries in an encyclopedia database. Navigation through printed encyclopedias in the traditional sense focuses on the alphabetic order of the entries. In electronic encyclopedias, however, thematic structuring of lemmas and, of course, extensive (hyper-) linking mechanisms have been added. This paper will focus on showing developments, which go beyond these navigational strucutres. We will concentrate on the semantic space formed by lemmas to build a network of semantic distances and thematic trails through the encyclopedia
