About Our Electronic Editions

We are beginning to release electronic editions of some books. At present these are only available by special arrangement on an individual basis. We do not use DRM in our electronic editions. (Please see our FAQ.) The only formats we support are EPUB and PDF; and each book will only be released in one of those formats. Most will be released in EPUB format. However, a few of our books require non-standard fonts and characters, so they will be made available in PDF, specifically formatted for good display on hand-held devices. Obviously we are not able to test our EPUB files on every possible device, but we do test with several, and with Calibre and Sigil on WIndows.  You can use Calibre to easily convert our EPUB format books to MOBI format for use on the Kindle.

E-BOOK Restrictions

E-books made available to individual readers are subject to some restrictions. Books marked in the catalog with a red circle are not distributed outside North America, except possibly to some enlightened parts of Europe. Books with a yellow circle are subject to case-by-case consideration. Books marked with a green circle may be generally distributed to adults in most countries. Our content rating applies strictly to books with a red circle.

About The Martian Women Series

As we like to say: This ain't your grandpa's Mars. Books marked with the ♂ sign in our catalog are part of the erotic Martian Women series. Eleven volumes are available now. We are sometimes asked about the erotic content of this series, so we have provided small icons on the catalog page to give some indication of the primary love relationships of the protagonists. Please take this with a grain of salt, because our basic philosophy is pan-erotic, and you will find more than one type of relationship in each of the books in this series.

About the Red Ai Imprint

Books marked with a small red circle in our catalog are part of our Red Ai series of love stories and (mild) erotically themed works. Look for the Red logo on the back cover. (This imprint has been discontinued.)

University Press Editions

SROP also acts as the underground distributor of controversial books by Kajolium Broadwick and Ginger Amelia Sprockette published by the University Press of Brnzklug Bafnerpolg. Because these works have been embargoed from distribution on Earth, we cannot guarantee their continued availability and curious readers are encouraged to purchase them at their earliest convenience.
