Julie Hirschfield Davis reports for AP:

The William J. Clinton Presidential Library is set Friday [today] to release more than 40,000 pages of notes, memos and other files, mostly from Kagan's stint as a White House counsel during the mid-1990s. It's the second installment in a 160,000-page cache of Clinton-era documents from Kagan's past.

By the wildest of coincidences, the prior batch of documents was also released on a Friday. See prior post here.

Update: The White House Counsel Office documents are here. I have not found anything about AEDPA in them.
