TITLE: Study of Set theory: Book recommendations?
QUESTION [7 upvotes]: Can you suggest a good book for set theory?
I have just started reading about Group theory and want to learn set theory on my own.
Thanks in advance

REPLY [12 votes]: The best rigorous treatment that I’ve seen at the senior undergraduate/first-year graduate level is Karel Hrbacek & Thomas Jech, Introduction to Set Theory. The first edition was already very good, and the third has been expanded to include some important topics that were not originally covered. I agree with the very favorable Amazon review by Michael Greinecker (who also posts here at Math.SE).
