If you are a new Linux user and wish for some direction in understanding Linux, then help is at hand. Unlike a few years ago when a Linux newbie had to solely rely on viewing the man pages or reading the manuals from tldp.org to understand the different facets of Linux, things are much different now. Thanks to the ever growing popularity of Linux, there are a plethora of books, manuals and howtos which make life much easier for a Linux enthusiast. It has also helped that Linux has continued to become easier to configure and use during this time.
Daily Artisan has put together a very good collection of links to free Linux books available on the net. The books span the gamut of Linux Installation, beginner guides, Security, System administration, Programming, Migration, Linux Kernel and of course books specific to particular Linux distributions such as Fedora, Ubuntu, Debian and so on.
