Missing a paper?

F-numbers (e.g., F1234) refer to "internal" papers (in preparation).
You found a reference to a such a paper? (Or maybe another paper which cannot be found in the database?)
Then you might find one ore more "child papers" in the list below.

Notes:

• If you found a reference to, e.g., Theorem 1 of F1234, and Sh:12 is listed as child of F1234, then unfortunately it is not guaranteed that the theorem is contained in Sh:12 at all (let alone with the same number).
• Previous numberings of Shelah's papers somethimes had the format AaShXx:345. In the current database, the number for this paepr is just Sh:345.
