    Abstract
    The purpose of this article is to look at the public libraries, university libraries and special libraries and information bureaus as online search environments in Finland at the beginning of the 1990s. Their challenges and opportunities are looked at by paying attention to their general and specific environments. The changes in the general environment of libraries are described briefly. The differences of specific online search environements are analyzed by paying attention to (i) the age of organisations and the establishment of onlines searches, (ii) the size of organisations and the division of labour in online searching, (iii) the available online information retrieval resources, (iv) the number of online searches, (v) the online searching policies, i.e. the participation of the clients in the search process and the adopted fee policy, and (vi) the clients of online searches. Public libraries, university libraries and special libraries and information bureaus clearly differ from each other as online search environments. So also do their challenges and opportunities differ. A common challenge for all search environments is, however, an ever clearer way to relate the costs of onlines earches to the profits received from them

    Abstract
    Considers intersearcher and intrasearcher consistency in the selection of search terms. Based on an empirical study where 22 searchers from 4 different types of search environments analyzed altogether 12 search requests of 4 different types in 2 separate test situations between which 2 months elapsed. Statistically very significant differences in consistency were found according to the types of search environments and search requests. Consistency was also considered according to the extent of the scope of search concept. At level I search terms were compared character by character. At level II different search terms were accepted as the same search concept with a rather simple evaluation of linguistic expressions. At level III, in addition to level II, the hierarchical approach of the search request was also controlled. At level IV different search terms were accepted as the same search concept with a broad interpretation of the search concept. Both intersearcher and intrasearcher consistency grew most immediately after a rather simple evaluation of linguistic impressions
