This is a great piece discussing the used book market, especially in relation to the online market and the publishing industry in general. It brings up the 2005 BookExpo America forum on the used book “conundrum.” The publishing industry has a growing list of boogie-men (rising on the list quickest is probably Google), but it seems online used booksellers are still the locus of one of their many complaints.

One sector of the book business that seems to be getting a lot of press is Spanish language books. One entrepreneur who has received some press recently is Rueben Martinez of Libreria Martinez. Martinez has been very successful running bookstores geared toward the Spanish-speaking community. A recent article discusses the growth of Spanish language books in the US market.
