Title
Guides To Specialized Search Engines (with Descriptions)
Description
Specialized search engines index collections of materials that relate to particular fields or subjects. This material can include information at websites, abstracts of documents that have not been put online, data gathered by the specialized engine, etc. In contrast, general web search engines index material found at websites about all subjects.
Specialized search engines vary widely in size, scope, and the type of materials they encompass. For example, PubMed, the huge search engine developed by the National Library of Medicine, contains abstracts of articles from thousands of medical journals worldwide, going back several decades.
There is no firm dividing line between a specialized search engine and a large searchable website. Whether a site can be considered a specialized search engine depends on the amount of information it contains, how focused it is on one subject, how specialized the materials are, whether it is continually updated and supplemented, and other factors.
