11. When searching for primary sources—fundamental,
authoritative, contemporary documents used to prepare later
works—historians often overlook the abundance of published
primary source material. Women's diaries, correspondence,
and autobiographies that have been printed either by the
women themselves or someone else, either at the time of
composition or centuries later, are primary sources and are
found in abundance in the General Collections.
In addition to primary sources, researchers also look for
secondary sources: books and articles describing and analyzing
occurrences outside the writer's personal experience. The
General Collections hold thousands of volumes of secondary
sources. An item can be both a primary and a secondary
source. When Mary Ritter Beard published her Woman as
Force in History (New York: Macmillan Company, 1946;
HQ1121.B36) [catalog record], she had created a secondary
source, a history of women. The volume becomes a primary
source when later historians examine it as a pioneering
contribution to the writing of women's history.
