The guidelines address two complementary issues: - INFORMATION contained in the bibliography entries, and - FORMATTING standards and tips. We hope that the community will understand the convenience and power of a bibliography database, and will promptly provide INFORMATION that is as complete and correct as possible. Formatting standards are not of primary importance. However, if you have not yet started a .bib file, some guidelines based on experience with the TeX Users Group bibliography collection may be useful. We anticipate that the success of this initiative will likely generate motivation to render the work as automatable as possible, to increase the features of this service, and to scale the project to other fields. If you have already prepared bibliography data in BibTeX form, we do NOT expect you to undertake a major overhaul to bring it into a form consistent with other bibliographies in the collection; we would much rather receive what you have now, rather than wait indefinitely long for a polished submission. Since it is expected that bibliography files will undergo continuous revision, it is easiest to incorporate polishing little by little.
