Building Accessible Websites, Joe Clark (2002, revised 2005)
•	Read free on joeclar.org/book 
•	Somewhat dated, especially in technology specifics, but still the canonical work on web accessibility with huge portions (especially related to best practices) still applicable
Accessibility Handbook: Making 508 Compliant Websites, Katie Cunningham (2012)
•	Easy to read and largely good. Some specifics are not best practice and some code samples are sloppy or erroneous
Pro HTML5 Accessibility, Joshue O Connor (2012)
•	Excellent and thorough but, unfortunately, overly reliant on ARIA, a sub-language intended to enhance accessibility but not fully or consistently supported by browsers, which we can hope for in the future but can’t rely on
