Hello,

I'm not quite sure if this kind of question can be posted on this board. Please excuse me if not.

I started studying real analysis with Rudin's Principles of Mathematics which was relatively compact. Then I bought Apostol's book which was much more helpful because it was more thorough and detailed.
So I was wondering if there are any other real analysis books that are very thorough. I don't mind studying very thick books. If you have any recommendations as someone who studied this area before me, could you let me know some of the books you consider good? I would really appreciate it. Thank you.
