I was just about ready to post a cautionary warning about referencing Greg Sadler (as he is a leader in modern Stoicism) but then:
1 - I checked the artice linked, and yes it is indeed a good comprehensive list of the surviving texts, and
2 - How can I criticize someone who writes?
So yes Greg Sadler's article is a good list of sources - I just don't recommend you follow him too closely on his views on Stoicism.
