Remember the editors did not write the entire book, so you must cite the separate authors of each chapter that you use. Articles in periodicals and journals differ in quality, content, and audience. While both can be useful sources, you must not presume they are of equal value to your work. The same caution applies to newspapers. Newspapers are often our only sources for current events, and can serve as a valuable primary source, but one needs to consider the type, circulation, and respectability of the newspaper, the audience, the time the author spent in producing the article, and the topic in its larger historical and cultural context.
Archives are special collections in a library.
They often contain manuscript drafts, personal letters, memorabilia, notes, diaries, account books, birth and death certificates, wills, etc. One often needs to obtain special permission to use manuscript collections in libraries. Some of these documents are available on microfilm.
