Site offer When there's only room on the shelf for one book, Unleashed is the answer. Sams' Unleashed (http://www.pearsoned.co.uk/Bookshop/subject.asp?t=122&affid=TRE&item=6863) series is designed with the technology professionals in mind, those who already understand the basics of a technology (or who are familiar with other closely related technologies), and who either want to expand their knowledge or want to be able to solve specific advanced-level problems.

Titles cover operating systems, networking, programming, databases and web development. The books are organized so that coverage of each sub-topic stands on its own, providing a depth of coverage not found in an average tutorial or introductory reference book.
