JUVENILE CATALOGS How to order This is a self-made website by little old me, and while it might be big, it is not sophisticated.  The little  icon takes you to a generic order form where you can type in the author, title, price, and indicate whether you would like to send me a check or PayPal payment.  I will confirm availability via e-mail, and once I've received payment, I'll ship the book.  It's that easy.  If you have questions,  please don't hesitate to ask  via email. Condition Grades There's a standard bookseller vocabulary, with terms like Fine, Very Good, Good and Poor to assess condition (to see these terms defined, click on the link above).  Most of my books are in Very Good or better condition, and I tend to overemphasize their flaws so that any surprise is a pleasant one.  Feel free to ask questions, and if the book isn't in the condition described, you may return it for a full refund.  Wants Lists If I don't have the book you seek in stock, I will retain your book search in my wants files and email you when I do have a copy for sale. If you don't hear back from me immediately, that probably means I don't have a copy right now.  But fear not,  I keep extensive files and never stop looking....  so send me your request;  you've got nothing to lose! Not listed? Not everything is listed on-line. Let me know what you're looking for. Book Search Form In Print Books If it's in print, I can get it for you. Just ask me.
