This study examines 539 references from 183 single-authored philosophy
monographs, excluding collections of essays, published in 1994 and in
dexed by Philosophers' Index, with each reference counted as frequentl
y as it was cited in the randomly selected citations. The citations we
re classified as to source type (book, article in book, journal articl
e, manuscript, thesis), language, the gender of both citing and cited
authors, the citing authors' attitudes toward the cited material, the
subject correlation between citing and cited sources, and the chronolo
gy of the citations. The type of presses publishing philosophy monogra
phs and which journals are cited are also discussed. While many contem
porary philosophers consider their discipline more related to the scie
nces than to the humanities, their citation patterns are typically hum
anistic, with the bulk of citations to books rather than journal artic
les and the citation of much material older than 20 years. The topics
studied were found to be predominantly 20th-century with an emphasis o
n analytic philosophy and little concern for recent trends in continen
tal philosophy, except for feminist philosophy. A quarter of citations
were to disciplines outside philosophy.
