Free Linux+ Study Guide : CompTIA : IT Certification :

OK guys, After almost 3 weeks of typing on and off, I have finally finished the Linux+ Study Guide. It takes a great deal of typing to put a study guide together, especially if you’re like myself and just highlight as you read, without taking notes in Microsoft Word. I hope you find this Linux+ study guide useful, should you decide to take Linux+ in the near future. Also please feel free to comment on it. I know my word skills suck, especially after typing 66 pages, but please bare with me. Additions and comments will be more than welcome

Only had a quick read of this but it looks very good as a general reference guide to Linux. Well worth a read. The only format that is missing in my opinion is eReader but that is easily remidied with OpenOffice.
