ETANA stands for Electronic tools and Ancient Near Eastern Archives. It is an incredibly useful resource run by the following bodies:
The purpose of this website is the online publication of archaeological monographs and journals, either as excerpts or whole publications. In addition to this a number of archaeological projects in the ANE have added in-depth information on their projects.
Originally intended for Ancient Near Eastern studies, it contains a good number of Egyptological publications. (e.g. see my link to Petrie's Memphis I on the left).
I find the website slightly confusing as the listing and the interlinking is not very neat, but the sheer amount of resources more than makes up for this.
