Which book would you like to see "texified"? Let's see if we could use MO to put some pressure on certain publishers...
Although it is wonderful that it has been put 
online, I think it would make an even greater read if "Hodge Cycles, Motives and Shimura Varieties" by Deligne, Milne, Ogus and Shih would be (re)written in the latex typesetting (well, if I could understand its content..).
But enough about my opinion, what do you think? Which book(s) would you like to see "texified"? As customary in a CW question, one book per answer please.
 A: Marcus - Number Fields
A: Chern - Complex manifolds without potential theory
A: Leon Simon - Lectures on Geometric Measure Theory
A: "Lectures on Chevalley Groups" - by Robert Steinberg
A: Palais - Foundations of global non–linear analysis
A: Adams - Lectures on Lie Groups
A: EGA, with hyperlinks for easy navigation.
A: Paul Cohen - Set Theory and the Continuum Hypothesis.
A: Robin Hartshorne's lecture notes on projective geometry.  This appeared as a book and is now out of print.  The pages appear to be photographs of pages produced with a typewriter, plus hand-drawn illustrations.
Maybe a wiki should be set up where volunteers can transcribe from the book.  Permission from copyright owners might be easy to get if they're not interested in continuing to publish it themselves, and if they are, an attempt to get permission for such a wiki might pressure them to put it back in print with better typesetting.
A: "Rational Homotopy Theory and Differential Forms." by Griffiths and Morgan.  
A: Stong - Notes on cobordism theory
A: Milnor - Lectures on the h-cobordism theorem
A: Atiyah - K-Theory
A: All the SGA's. Note that SGA 1 and 2 already exists in TeX, and there is something for SGA 3 and 4.
A: Rolfsen - Knots and Links
A: Atiyah + Macdonald, Introduction to Commutative Algebra.
A: Michael Reed. Abstract Non Linear Wave Equations.
