Tips for evaluating Web databases

Abstract

Evaluation of WWW databases are problematic because of their ephemeral nature, and because of misspellings, alternative spelling and the differences between British and American English. They can still be evaluated on scope (is the coverage adequately explained), structure (does the structure of the record facilitate effective retrieval) and currentness (is the record up-to-date). Offers pointers for evaluation using these criteria
