The list on here previously is now largely out of date. Use the list on the book page for Introduction to Axiomatic Set Theory.

I have now finished all the proofs in $\S 1 - \S 9$. Basis Representation Theorem for Ordinals is just proven. $\S 9$ is done! Skipped Well-Founded Recursion, though. May come back to it later.

Judging by the length of the proof, I expect Sierpinski's proof that $\operatorname{GCH} \implies \operatorname{AC}$ to break the record for page length on this site.

Template for me...
