You all probably already know about this, but I only just found it, and it's great. Started in 2005 as a joint project between the Boston Museum of Fine Arts and Harvard University, the Giza Archives Project is an amazing online source of information/materials about ancient Egypt. Here's a quote from the official web site:
The present Web site contains six basic categories of materials, four of which derive from the original Harvard–MFA Expedition.
* about 22,000 black-and-white excavation photographs taken between 1902 and 1942
* about 3,106 Expedition Diary pages
* about 2,408 Object Register book pages (containing 19,544 individual object records)
* about 10,000 maps and plans, ranging from entire Giza cemeteries to individual burial shafts
* about 200 books and articles on Giza (a digital Library of PDF files)
* experiments in Interactive Web technologies, such as zoomable satellite photos and 360-degree panoramic views of the site using Quicktime Virtual Reality (QTVR) and other technologies.
