I would ask that all aspiring lithographers consider getting both the old and the new Tamarind books. The original "The Tamarind Book of Lithography: Art & Technique" is far more comprehensive (maybe overly so) albeit some of the terms (and materials cited) are outdated. However, most of today's students/artists/printers are less inclined to spend time to leafing through the multitude of cross-references within the book to problem solve. The updated Tamarind book is far easier to use so in that regard Tamarind has responded to today's learning environment. Like lithography itself, there is no one answer. If I had to list my tried and true references for litho I would recommend the following in addition to the aformentioned two books.
-Tamarind's "Aluminum Plate Lithography: A Manual" available at Tamarind (excellent, fast, workshop reference)
-Tamarind's "Photolithography: A Manual" available at Tamarind (ditto)
-Two books authored by Tamarind Master Printer Paul Croft "Stone Lithography" and "Plate Lithograpy" (goes into more detail than the manuals but not as comprehensive as the two "Tamarind Books"
The manuals are easy, short and walk the reader through preparing, processing, printing and problem solving (I believe they were written in large part by TMP Jeff Sippel). Of all the books I used to help students the manuals were the ones students actually "stuck to". However, the "original" Tamarind book and its predecessor are excellent timeless references. Timeless. The newest version is so gorgeous aesthetically that I am afraid to take into the shop. One aspect of the new book that is reassuring is the uncompromising discussion about curating and documentation. It is a nice contrast to web sites and blogs citing....well, other than accurate information. Lastly, I love the book because of the notion that a book about an outdated, punishing, and time consuming medium can still be published with meticulous due care and attention to detail in an era of instant gratification.
