Human Relations Area Files (HRAF)
The Human Relations Area Files (HRAF), a microfiche collection of information on more than 330 different ethnic, cultural, religious, and national groups worldwide, is used by social scientists and students studying a particular culture or cultural trait or for making cross-cultural analyses. Included are more than 750,000 pages of text from books, articles, and unpublished manuscripts as well as English translations of foreign texts available exclusively in HRAF. In 1937, under the direction of Professor George Peter Murdock, researchers at Yale’s Institute of Human Relations began to design a classification system for organizing cultural, behavioral, and background information on a society. Out of this Cross-Cultural Survey came the Outline of Cultural Materials (OCM), a universal topical classification scheme categorizing human activity into more than 700 categories, such as “settlement patterns” and “serfdom and peonage.” This system was used extensively by the government during World War II to classify information on modern societies.
Outline of Cultural Materials. 5th ed. 1982.
Subject index to HRAF. Assigns a numerical designation to more than 700 categories of human culture. Used in conjunction with the Outline of World Cultures to locate information in HRAF on cultural traits of particular groups. Mugar Micro X Z5111 M86 1982M. HRAF also has an online edition of the Outline of Cultural Materials.
The OCM uses a three-digit code to assign subject categories to cultural traits. For example, the OCM codes for “settlement patterns” and “serfdom and peonage” are 361 and 567, respectively.
HRAF materials are arranged by culture. All texts containing information about a particular culture (e.g., Amish, Hausa) are grouped together. Each culture collection is identified by an alphanumeric code according to the Outline of World Cultures (OWC).
Outline of World Cultures. 6th ed. 1983.
Classifies all known cultures of the world by geographic region. Assigns alphanumeric designations to cultural groups. Mugar Micro X Z5111 M87 1983.
In the OWC, cultures are classified according to geographical regions:
- M=Middle East (including Muslim societies in Africa)
- N=North America
- R=Russia (cultures located in the former Soviet Union and Russia)
- S=South America
In the examples given above, the OWC codes for Amish and Hausa are NM6 and MS12, respectively.
How to use HRAF
- Locate your topic in the index of the Outline of Cultural Materials (OCM). Note the corresponding 3-digit category number (for example, 593 for family relationships). Check the category description in the text of the OCM to make sure that the category you have selected covers the topic in which you are interested.
- Locate your culture in the Outline of World Cultures (OWC). Note the letter/number code (OWC code) for that culture (for example, NT17 for Taos). To see whether files are available for that culture, check the list of “Human Relations Area Files Available” at the end of this research guide. Only about ten percent of the cultures listed in the OWC are covered in the HRAF archive.
- Go to the HRAF microfiche files and find the set of microfiche on your culture. [In Mugar Memorial Library these are housed in the Current Periodicals Room.] Files are arranged in the same order as they are in “Human Relations Area Files Available” (alphanumerically by OWC code). The name and OWC code for the culture appears in the header of each fiche.
- Find the fiche containing the information on your topic. Subject category numbers are on the upper left corner of each fiche. Categories are arranged in numerical order within each file.
- Looking at the fiche, you will notice “flashers,” eye-readable category numbers that tell you where each new category begins. Each category contains pages of text from books and articles on your culture. In the sample following, all information on Taos (NT17) family relationships (OCM code 593) will be found after the 593 flasher.
- Center the first page in your category on the microfiche reader screen. Only the pages containing information on the topic within your category are located in that category; do not expect to find entire articles or books. Each page is identified by a “source number” (each book or article is a source), followed by the author’s name, both located on the upper left corner of each page. This is followed by a code letter indicating author’s training (see key, below), a code number indicating source evaluation (see key, below), and other information. See page identification key, below.

Citations to all documents in the HRAF are organized by cultural unit and are updated annually. Arranged in alphanumeric sequence by OWC code. Mugar Micro X Z5111 F69 1976M.
- OCM category 112 contains bibliographical information on sources consulted by HRAF staff but not processed for that file.
- OCM category 113 contains bibliographical information that appears in texts included in the file, such as footnotes, endnotes or reference lists.
- OCM category 116 contains copies of entire texts (e.g., books, articles, manuscripts) processed for the file. It is especially useful if one wishes to see the entire document from which a given page has been taken. Because of copyright restrictions, not all documents will be found here.
