I started selling books by catalog in 1993 and joyfully migrated to Internet sales in 1996. In the early days of bookselling on the internet, I sold books through Interloc, Abebooks and Bibliofind. I even sold books to Amazon when their out of print department consisted of someone calling on the phone and asking if a book was available and then sending you the payment, PRIOR to shipping the book.
Flash forward to present: Interloc is now Alibris, Bibliofind was bought by Amazon, neglected to death and then shut down, and in this year alone, Abebooks bought Chrislands (which hosts my bookstore site) and less than 2 months later, ABE itself was bought by Amazon.
And me? I will be publishing my first print catalog since 1995, which will hopefully be mailed out in January 2009.
