The Pollen and Spore Circulars

Pollen and Spore Circular #12, May 15, 1946
Pollen and Spore Circular #12, May 15, 1946

The Pollen Analysis Circulars, succeeded by the Pollen and Spore Circulars, were produced beginning in the 1940's as the number of investigators and literature on Quaternary pollen analysis began to explode. Originally edited by Paul Sears of Oberlin College and Yale University, and later by Paul Sears, L.R. Wilson and C.J. Heusser, these hand-typed documents served as a means of bringing those interested in pollen analysis together before any formal publications specializing in palynology were established.

The first issues (1 through 4) were distributed in 1943, followed by four more in 1944, three in 1945, two in 1946, two in 1948, and one in 1949, with the final issue appearing in 1954.

Below we have reproduced the 18 issues as PDF's. The original documents were mimeographed sheets, and many of these have discolored and faded.

These documents are interesting from an historical point of view, and make entertaining reading. In fact, the term "Palynology" was suggested by H.A. Hyde and D.A. Williams in Issue 8 (1944) as being the "right word" for the subject.
