When Ubuntu Pocket Guide and Reference went on sale in January, I created a Web site to redistribute the free edition and act as a central information source for the book. And because the book was about Ubuntu, I made ample mention of the word "Ubuntu" and also used the familiar three-part circle logo.

In this book, the creators of the popular jQuery learning resource, learningquery.com, share their knowledge, experience, and enthusiasm to bring you a comprehensive reference to the popular JavaScript library.

Martin Owens, the leader of the Ubuntu Massachusetts Local Community (LoCo) Team and general guru for things GNU/Linux, has published a delightful little book (currently in draft form) that explains the concept of Free and Open Source Software.

The task this book sets out to do is impossible and many who purchase the book will expect a great deal more. Everyone wants a one volume answer guide to the Ubuntu Desktop, it simply is not possible. The goal of the current book, is to provide “jumping-off point to get started.”

Getting onto the ‘Linux ladder’, making your first steps into the world of Linux, can be daunting, especially without support. There are lots of books specifically targeted towards beginners and Ubuntu, and Apress’s Beginning Ubuntu Linux, by Keir Thomas and Jaime Sicam is one.
