Descripciones mejoradas de Syndetics:

A subject guide to some 34,000 print and other sources of information on all aspects of the environment, providing a place to search for facts, opinions, practical advice, etc., at any level of interest or expertise. About 1,100 environmental subjects are covered by 13 different types of information sources such as encyclopedias and dictionaries, online databases, and research centers. Two arrangements of the data enhance the value to a multiplicity of users: the subject arrangement allows access to information for specific topics, while the "Sources Cited" section provides access for users having a particular source or organization in mind. The topics included range from often-explored issues such as air pollution, global warming, and radon to more obscure topics such as buffer species, integrated pest management, and teratogenic agents.

CHOICE Review

This work has three sections: an "Outline of Contents" containing see and see also references (essentially an index); the main section--1,508 pages--consisting of sources (including nonliterature sources such as professional societies and research institutes) arranged by subject; and an alphabetical list of sources cited. Subject headings range from very broad to very narrow, subarranged by type of source. This arrangement should be very useful, but in execution it has created enormous redundancy of information, hence the work's extreme size (and high price). Entries for general indexes, encyclopedias, online databases, etc., repeat over and over again under different subject headings. Some very specific subjects--including some individual chemical substances--list nothing but these very general sources. Selection of chemicals for inclusion appears haphazard. Marginal and inappropriate sources are included under some headings. Many (but not all) entries have brief descriptive annotations; some annotations are erroneous. Sources appear to have been selected almost at random; outdated sources are cited, and the same source may be listed twice with slightly differing citations. The intended meaning of some subject headings is unclear, as there are no scope notes. Cross-referencing between headings is inconsistent and sometimes inaccurate. Many useful sources are contained in this large, heavy, and poorly-bound volume, but given its expense, serious flaws, and the availability of numerous other environmental reference works, it cannot be recommended.
