hi everybody,

i'm a computer science student and almost everyday i need an online book about a certain subject or what ever ,but i really don't know from where can i download free books or pdfs. i searched a lot using google and other search engines ,either i find unhelpful books or others that i must buy and not for free.does any one know from where can we find and download computer science books like for example :

Algorithms and Data Structures: The Science of Computing - Page 583

by Douglas L. Baldwin, Gregg W. Scragg - 2004 - 620 pages

or anything concerning file structures using java or what ever ?

i would be very very grateful to find a reply and thanks in advance.
