This article is from the Tom Holt FAQ, by Nick Boalch email@example.com with numerous contributions by others.
"The Tom Holt Webpage" (Calle Aasman)
Calle's webpage is the definitive source for all things Holt-related.
Includes a biography, complete bibliography (probably the best anywhere),
plus many extras such as a random Holt quotation generator and some of
Tom's short stories to download. Well worth a visit.
"Tom Holt" (Orbit Books)
The generic page about Tom created by his publishers. Contains a brief
bibliography but is generally not particularly interesting.
"Tom Holt Bibliography" (Uwe Milde)
Complete Tom Holt bibliography. There's not a great deal more I can say.
It does exactly what it says on the tin...
"Tom Holt page" (Paul Bines)
A general Tom Holt page, containing an illustrated bibliography, an
interview with Tom and links to other resources.
"Alt.Books.Tom-Holt page" (Dragonprince)
Rather than a site about Tom, these pages are dedicated to the abth
newsgroup, and especially to any alt.books.tom-holt meets going on around
the world. Read the reports! See the photos!
TomHolt.com (Dragonprince and others)
General information about Tom Holt and useful notes on the "Village of
Abthite" -- essential reading to make sense of this newsgroup!
