1. The Literature of Ancient Sumer - Jeremy Black. It is a quite substantial anthology, has myths, hymns, laments, royal praise poetry, proverbs, literary debates, etc.

2. Myths from Mesopotamia - Stephanie Dalley. I bought this for Gilgamesh, loved the rest of it too. One of my most treasured books.

3. Weavers, Scribes, and Kings - Amanda Podany. Not Sumerian literature, but my favorite comprehensive history book covering all of Mesopotamian history. I mention this particularly because all the literature we do have came to us through scribes, and this book gets into whatever we can know about their internal lives really well. Reading about their tutoring and how they learnt to write, what we can deduce about how their lessons were structured - fascinating stuff.

For such an ancient civilization, it is astounding how much we do have and how closely we can meet them.
