What are some books that have works of mathematicians?

Question

I am looking for a book that have important works of mathematicians before 21st century. I am not looking for any particular mathematician but it will be nice if the matter is arranged in topic wise format, like all great works in algebra etc. I am not looking for historical or philosophical books but the original works, edited to suit modern symbols and language.

Thanks a lot.

Answer 1

You could try "God Created the Integers: The Mathematical Breakthroughs That Changed History" by Stephen Hawking. I think it fits your description accurately, except maybe (IIRC) the modern notation part.

Answer 2

You could try and own a book that talks about Ramanujan's lost notebook. The finders of the book laid out the assertions he made in context with contemporary mathematics. This book is the 8th listed here.
