Welcome to the online home of J2U Books, also known as Caterwaul Books..
This Library is owned by J. Jeff Ungar. We began officially in 1998 after ten years of book collecting when we could no longer get into the office because of all the books stacked about. (It still seems like the more books we sell, the more we have!)
While our initial focus was on Science Fiction and Modern First Editions, we have been expanding in more of an eclectic direction, trying to stock something for everyone. With less than 40% of our stock on line, we welcome your want lists and inquiries.
