摘要：

A summary is given of the information on lichen products reported in 295 papers, most of which appeared too recently for inclusion in the book Chemical and Botanical Guide to Lichen Products by Chicita F. Culberson (1969). The new references are primarily from the years 1965 to 1968, although many are from 1969. The chemical guide summarizes the recent literature on primary and secondary lichen products, of which 90 are new to lichens. The botanical guide covers revisionary and confirmatory reports on taxa previously studied as well as chemical data for 682 taxa not included in the book.
