Some time ago, I noted that the Heinlein Archives were a special collection of UC Santa Cruz, and how a holy pilgrimage was in order.

Not that going to Santa Cruz is an especially daunting trip, it turns out I don't need to to see most of the contents. They've been digitized and reasonably priced PDFs are available at heinleinarchives.net. There's his critique of the draft of The Mote in God's Eye, notes toward a writing book, story notes and fragments, snide comments written by Heinlein and Virginia Heinlein in the margins of Alexei and Cory Panshin's review of Time Enough for Love, various proposals, treatments, and scripts for TV and film work, including a proposal for Abbot and Costello Move to the Moon (!) and pretty much everything this side of laundry lists and dry cleaning receipts (OK, maybe those, too -- I haven't looked through everything.)

I also recently learned about The Virginia Edition, a deluxe hardcover complete works of Heinlein that can be yours for the low, low price of $1500. Looks like about half of them are already available; the balance will be shipped as they're ready. Want.
