Unreleased oWoD books?

While perusing listings on Amazon.com I have found some entries for White Wolf books I never knew existed, mostly for Dark Ages: Vampire. Two of them are "Dark Ages: Italy (Dark Ages Vampire)" and "Dark Ages: Brujah Chronicles (Dark Ages Vampire)". Were these titles that were abandoned when White Wolf in their infinate wisdom decided to cancel the Dark Ages line in favor of V:tR? Are they lost forever like "Kithbook: Boggan" or were they briefly released as PDF files such as "Terra Verde (Trinity)", "Witches and Pegans" and "Van Richten's Guide to the Mists"?

I know of two books for my favored system. 'Aberrant; Underworld' was only available as a .pdf document and sold via the White Wolf website. Additionally, another book that was never sold, 'Aberrant; Brainwaves' was largely written by one of the game's former Developers. The only place I know of to get it is www.nprime.net, a pbp RP Aberrant forum.
