As part of an investigation of the stratigraphic and environmental distributions of siliceous algal resting cysts, we have assembled this bibliography. The emphasis is on papers that illustrate these cysts, and our annotation concentrates on the nature of the illustrations. In some cases, we have also listed taxonomic names of the species illustrated in the paper, as well as those of any new species described, but this part of the annotation is not yet complete. The taxonomic names given here are always those given by the original author. The references have been selected by starting with a few papers and extracting relevant titles from their reference lists. We have included not only relevant works, but also a few that sounded relevant but turned out not to be.

This bibliography is, we believe, fairly complete for references that describe fossil occurrences of cysts, but much less thorough for the taxonomic literature. The list of references is still evolving, and we welcome additions or corrections.

We have checked and verified many of the references listed here; those that we have not yet seen are indicated by an asterisk preceding the authorship. We have also indicated the source of each reference which we have not seen. Most such references were found in the reference lists of other papers listed here. Other references have been taken from the VanLandingham bibliography, which is an unpublished manuscript on file at the Diatom Library of the California Academy of Sciences in San Francisco.

We wish to thank Mrs. Margaret Hanna, curator of the Diatom Library at the California Academy of Sciences (San Francisco) and Mrs. Jacquelyn Freeberg, of the USGS Menlo Park Library, for help in locating many of the references, which are often tantalizingly obscure.

Some of the references are incomplete; they have been included anyway in order to preserve as much information as possible. For the same reason, the bibliographic style of the references is not consistent throughout; we prefer to include such information as the authors' full names and issue numbers of journals when we have it available, rather than discard good information about one paper just because we lack similar information about another.
