Often it is useful to find articles published at the time of an event. Many online indexes do not cover publications from before the last few decades. Some printed indexes provide access to earlier publications. Peter Smith, 1938. Indexes over 590,000 articles in 479 American and British periodicals.
Main set consists of a subject index.
Information given about each article includes its title, author's name in parentheses when it was known or could be ascertained, abbreviated title of the periodical in which the article can be found, and volume and page reference. There is also a table decoding the periodical title abbreviations. Carrollton Press, 1977-1978. Indexes a select collection of history journals. See the inside cover of each volume for journal names.
