This series is comprised of Dr. Forward's collection of science-fiction and non-fiction books by other authors, many of which contain author inscriptions or autographs. The bulk of the texts include brief, inserted notes written by Forward that address his relationship to the author, either as a colleague, advisor, or fan. Dedications or acknowledgements of Forward and his work that appear in a text are also meticulously noted. This information, when available, is transcribed in a supplementary note.
