I'm looking for an out-of-print Czech book (Televize ve světě by Milan Šmíd, Edice Čs.televize, 1989). Is there an online directory of secondhand Czech bookstores that you would recommend? Is there a service (a Czech equivalent of Abebooks.com, for instance) that enables users to search through the catalogs of a various secondhand booksellers at once? I would appreciate any advice; where to look, whom to ask... Thanks in advance!
