Publisher: Europa Books Limited/Pad Library, Los Angeles[this book is indicative of a bibliographical problem found elsewhere in both the Ed Wood Collection and in the greater adult paperback business. Due to the illegal nature of many publications, tax evasion, reusing old book components for new publications, and ties to more savage legal infractions, companies were constantly starting, collapsing and renaming themselves in a fly-by-night fashion. Therefore we find ourselves with situations like Strange Sisters which has a Pad Library ID# on the cover, yet on the verso of the title page we find the publication credit attributed to Europa Books Limited. Obscured by a fog of criminality it is quite difficult to know where one company ended and another began. It is highly likely that the amalgam of imprints were owned by only a few people. For instance, Michael Thevis of Pendulum was said to have owned 90% of all adult bookstores during the 1970s. Viceroy Books and Private Editions Books shared the same Canoga Park address.
