documents are the books, journal articles, dissertations, or
manuscripts in the HRAF database.
These full-text documents cover most aspects of cultural
and social life – from basket making to infant toilet training
to funeral rites. In each document, every paragraph is indexed
with OCM subject
codes, allowing you to search for subjects at the paragraph level.
In addition to its text, each document contains publication
information, a short abstract, place and time coverage, and a
table of contents. Figures,
bibliographic references, indices, and appendices may also be
opening a document from the File
TOC, you will see the page divided into two sections: right
and left. The
right-hand side contains publication information, which includes
the author’s name, the document title, the publisher, and an
abstract written by a HRAF analyst. Also listed in this area are the main OCM Subject Codes for the document, to give you
a sense of information you can find.
For example, our sample document The Sun God’s
Children is mainly about such topics as History (OCM 175),
Hunting and Trapping (OCM 224), Diet (OCM 262), and Mythology (OCM
773) for the Blackfoot. Other
information (such as the document’s field date, coverage place
and date, and type) can be found by clicking the “go to long

left-hand side of the screen contains the document’s table of
contents. Depending on the type of document, you may see chapter
titles, or just headings titled “section” (if there were no
named headings). The
words in these chapter and sub-chapter titles can be used to
search for information in Text Search, as will be discussed later.
Clicking on a chapter title will open up that chapter in
the right-hand window.
OCM Subject Codes
at HRAF read every paragraph in our database, indexing each with
OCM Subject Codes (OCMs) that summarize the main topics of the
paragraph. The number
of OCMs for a given paragraph is determined by the variety of
topics that paragraph covers, meaning some paragraphs have only
one or two OCMs and others have several.
The paragraphs in Figure 6, from The Sun God’s
Children, discuss the mythological relationship between humans
and animals, and so are indexed with the OCM for mythology –
this chapter is a narrative, told by Chief Crowfoot, so it is
indexed with OCM 903. The
names and descriptions of each OCM category can be found by
clicking on its subject code number.

page headings (fig. 6) found in the body of each chapter contain
information such as the culture name, field date, publication
date, location, and date coverage.
In the current chapter, there is reference to
“northwestern Plains, Montana, United States,” giving us the
location of the Blackfoot.
