Periodical articles are generally more specific topics than books.
To find articles, use an appropriate subject specific periodical index or abstract. Once you have selected some articles, use the Periodical File to find the journals in the library. Newspapers are good sources for recent developments on current events or contemporary accounts of past events. Few newspapers are indexed in periodical indexes.
