Many of Ruby's books are still readily available. One of the best online bookstores is Amazon.com which I highly recommend. They can special order any Ruby Jean Jensen title in print for you. If you'd rather not order Ruby's books through the internet, then you can purchase them in your local bookstore or have them special order your request.

Unfortunately, Ruby's books from the 1970's, with the exception of HOUSE AT RIVER'S BEND, are out-of-print at the moment. So that means you'll have to direct your search towards used bookstores. I recommend readers to check out The BookFinder at least once a week. This is a service which searches through the inventories of numerous used bookstores and this is a great way to locate many of Ruby's older titles. Bibliofind is another similar service which is also good.

Both of these used bookstores stock a large inventory of horror books and are worth trying:

Pandora's Books
AAll-Electric Paperbacks

If all else fails, you can contact a company which actively searches for out-of-print books. I have used the following services in the past for locating Ruby's out-of-print books, and they are all efficient. There is no charge to initiate a booksearch with any of these companies, either.

Abracadabra Booksearch
Book Hunters
Book Search (by Susan)
OutofPrint.com

Good luck with your search! Remember to be both patient and diligent.
