The New Mexico Book Association has just published the 3rd edition of their directory and book resource guide, New Mexico's Book World, and they are making the whole 140 page book available free online. It contains chapters with listings for New Mexico publishers; book organizations; booksellers; publishing services; libraries, etc.-- and a ten-page essay by Lynn Kline surveying New Mexico's literary past. (Did you know that Robinson Jeffers was a regular visitor at Mabel Dodge Luhan's home in Taos?)
They will update the website version every couple of months. Their monthly newsletter, Libro, is also available free online.
