    Rebinders
    • There are some publishers who strip the covers off a paperback book and rebind it in hardcover for libraries. Sometimes they put the cover art on the new hardback. Sometimes they issue a new ISBN. These may be different names for the same rebinder because they all use the same ISBN prefix: BT Bound, Econo-Clad, Sagebrush, Turtleback. Some are distributed by Demco Media.

    Signet and RoC
    • I wish I knew a bit more about these twyo. Both have used ISBN 0-451... (also used by Onyz books). RoC has also used the Penguin 0-14.... Both are now imprints of Penguin Group USA.
    • Some online listings of books indicate "Signet/RoC," such as Shadows of Doom, ISBN 0-451-13815-5. It has the Signet symbol on the cover, but Amazon lists RoC as the publisher.
    • I think that Signet began as the science fiction imprint of the New American Library around 1948-1950.
    • The earliest book with RoC on the cover that I have seen: The Copper Crown, RoC, ISBN 0-451-45050-7 (1986).
    • Signet and RoC are both still publishing in 2007. The editors for the RoC imprint are also Ace's current publishers.
    • With this in mind, I shall list any "RoC" pre-1986 book as Signet unless I find RoC on a cover or title page before 1986.
    • I have listed some Signet numbers elsewhere.
    • ISBN Prefixes
      • 0-14... (The Penguin prefix used by RoC)
