Ok, so yesterday I managed to back up my Literature directory to a DVD disk. And I discovered that I have 3,18 gigabytes of written stuff. So taking everything in categories(I really need to categorize my books) I have:
1. Math books (1,3GB from calculus to algorithms and probability theory)
2. Engineering books (not much, but there are stuff like Lego Mindstorms book and similar things)
3. Computer stuff (didn't count how much but it's quite a lot. Mostly about programming and computer security).
4. All kinds of references(x86 CPU reference from Intel, PPC reference, RFC archive and more)
I hope I'll be able to read at least a fraction of my library some time. And not only read but study.
