Some sources
Hi Sarah,
Your wiki looks great so far!
I know its early, and you have not written some of your sections yet, so you may already have these sources, but I thought I would just suggest some that I am aware of in case you haven't discovered them yet.
Larsen, M.T. “What They Wrote on Clay.” In Schonsboe and Larsen, eds. Literacy and Society. Akademisk Forlag, Copenhagen, 1989, pp121-148.
Pedersén, Olof. Archives and Libraries in the Ancient Near East 1500-300 B.C. Bethesda: CDL Press, 1998 (which you might have as I checked to see if it was still available at IKBL and it is on loan)
Best, Hannah
