Print indexes are periodical indexes in paper format that organize periodical articles by subject. Subject terms listed in the indexes are in alphabetical order. Some examples of print indexes are:

· Readers' Guide to Periodical Literature

· Social Sciences Index

· The New York Times Index

Since most electronic indexes do not index articles prior to the 1980s, print indexes can be helpful in researching historical topics. The Library has some print indexes dating back to the early 1900s. If you want to read articles written during the Vietnam War to gain an understanding of people's feelings about the war, a print index from the 1960s or 1970s may be helpful in locating these articles.
