Over the years, I've read or been recommended a number of books which are essential reading for professional web developers. I've compiled the list of books below to help the community find a comprehensive list of good books that can help them be better coders. This is certainly not all inclusive and I'm sure there are other books out there that have been great. If you feel very passionate about a specific title, let me know via the comments and I'll check it out.
