If you know a publisher specialising in your area, it may be useful to check such sites regularly. Try Eldis's list of Publishers' WWW Sites . John Hopkins University Press Booksellers with WWW sites may have subject-focused lists of new publications. Many of these are commercial databases and require a subscription. Your organisation may have an account with some of these.
Some databases are available free of charge.
Some cover costs by charging for supplying copies of articles found, some offer free access to basic information on the article but charge for viewing the abstract. Some libraries also include articles in their catalogues. Some publishers make available the contents pages of their journals. Check local library catalogues for journal holdings. News agencies and television services also offer online versions.
