Back on Feb 20,2012 I added another torrent to my Rarities thread on Demonoid, "Philip Francis Nowlan - The Original Buck Rogers (2 ePUBs)"
this quote from my description is pertinent to the origins.
Armageddon 2419 A.D. is Philip Francis Nowlan's novella which first
appeared in the August 1928 issue of the pulp magazine Amazing Stories. A
sequel called The Airlords of Han was published in the March 1929 issue
of Amazing Stories. In the 1960s, Nowlan's two novellas were combined by
ACE Books editor Donald A. Wollheim into one paperback novel, titled Armageddon
2419 A.D. The characters and setting eventually evolved into Buck Rogers.
For more sf and fantasy rarities, visit my (as Amontoth) Rarities thread on Demonoid, where you can read the descriptions or my cloud on MediaFire where you can download directly in rars.
Please note these are rarities
, and not necessary out of copyright.
As bobcdy has stated , this hobby (sharing Out of Print works) is a LOT of work, and the vastly differing posting requirements of forums such as here, Demonoid, Pulpscans, PBscans and other Yahoo groups, and direct dl sites such as Mobilism and Tuebl, makes it difficult to share with everyone.
This results in an insularity in each 'group'. I urge everyone to investigate these other resources. You will be pleasantly surprised with what you discover.
oh btw. kudos bobcdy
