Footnote - Night Of Delusions
The 1st edition Berkley paperbacks (with the brownish cover art by Richard Powers) are not actually Night Of Delusions. During the proofing process, the manuscript for Night Of Delusions was mistakenly switched with that of The Man In Question, a thriller by John Godey. Thus, the Laumer book received the Godey cover and visa-versa. A second printing by Berkley (with a blueish cover) is the true Night Of Delusions.
Thanks to Rich M. for pointing this out and to Eric of Weird Books for noting which edition was in error.
To avoid any confusion with this mis-printed edition, Tor republished (1982) Night of Delusions as Knight of Delusions.
Footnote - The Great Time Machine Hoax
This novel was originally serialized in Fantastic Stories, June, July, and August 1963 (Vol. 12 #s6-8) under the title A Hoax In Time.
A reviewer comments "The book version is longer, containing at least one major sequence not found in the serial and also a different order for the sequences found in both. The framing story is also somewhat different." - Steven S.
