It is designed to provide tools that both novice and expert searchers can use to achieve accurate and comprehensive results from their searches.
Bibliographic databases contain records which provide a description and sometimes an abstract.
Each record corresponds to a publication. Sometimes the publications described are primarily journal articles as in the CAB Abstracts. Usually a database was created to satisfy the information requirements of a particular audience and as such it may be very highly specialized. An example might be AQUA maintained by the New Brunswick Department of Fisheries and Aquaculture in order to record the location of sites of hatcheries, Bay of Fundy weirs, and Bay of Fundy marine aquaculture cages in New Brunswick. Another example might be the Soybean Adaptation Trial maintained by the New Crop Development office of the Department of Agriculture, Prince Edward Island.
