not sure if anyone had stumbled across this Free Book Search website—which seems to work like a metasearch engine. it might be helpful for people who like to scour the Net for freebies. it is definitely optional—considering the non-useful links dumped—but compared to a typical Google search, it seems to concentrate on books, reviews, and relative miscellanea more specifically.
there is a discreet link titled Search to the right of the book cover art work.
and free stuff means that it is usually free.
