Electronic catalog of the Library for Natural Sciences of the Russian Academy of Sciences as a specialized information retrieval system focused on a qualified user

The summary catalog of books and continuing editions of the Library for Natural Sciences of the Russian Academy of Sciences (LNS RAS) as an example of a fundamentally new approach to creating a library catalog like an information retrieval system is considered. This catalog reflects all the editions that are acquired for collections of more than 50 libraries included in the LNS RAS centralized library system (CLS). In contrast to the majority of Internet catalogs, the LNS RAS catalog allows one to handle almost an unlimited amount of requests that include any elements of bibliographic descriptions and subject classification headings connected by Boolean operators “AND,” “OR,” and “AND NOT.” A user is able to limit the search by the collection of any library, included in CBS of LNS RAS and also to search the books that are available in the full-text electronic version. The search results are presented in the form of advanced bibliographical descriptions and include publications' scanned pages such as title, abstract, and table of contents.
