I have some best bookmarks for you, compiled during my research for websites in Web Development, Education, E-books, etc. I have divided the bookmarks into 3 categories:
1) Bookmarks collected by me.
2) Bookmarks from Opera. For people with other browsers.
3) PC Magazine’s 2007 Top 100 Classics and Top 100 Undiscovered.

Intended Users: The bookmarks collected by me are specially for Students (Physics, Chemistry, Mathematics, Biology), Web Development Learners (PHP, Content Management Systems, Web tools), Personal Websites hosted by individuals, free E-Books.
I liked the PC Magazine’s 2007 top 100 Undiscovered. It really has some nice links. You may just wonder why were they hidden?
