I've been searching for some academic books I need for college for the past couple of weeks, I found most of them except for one.
So naturally, I spent most of my weekend looking for it, until I found it last night in this amazing website which contains hundreds, if not thousand, of books of all types!
Academic books, cookbooks, novels...etc. all in .pdf and .epub formats.
Here's a link that'll take you directly to the website: www.ebook777.com
I hope you find what you are looking for...
