The CodeDevelopr.com site has posted a handy reference list of 50+ guides and manuals that can make looking up those key facts easier.
This is a list of over 50+ Documentation Manuals and Guides for Programmers, Web Developers, and Web Designers. I will actively update this list with more Manuals as I come across them. If you would like something added, please leave it in the comments section below. Over time it will become more refined and better organized and in return, more useful so please bookmark and share with your friends.
