If you have any interest in Gnostic literature, you should know that G.R.S. Mead's translation of the Pistis Sophia is now available online at sacred-texts.com.

I should note that the way the HTML is set up, it really only works on IE. There are marginal notes that use CSS positioning in an IE-specific manner. The "Production Notes" state:

PRODUCTION NOTES: In the original book, running comments are placed in the margins. The web version of this text uses Cascading Style Sheets and DHTML to emulate this layout. Hence, to get the best view of this you will need a recent browser: older browsers will still produce readable results, though not as pretty.

However, when I view in FireFox, the marginal stuff is overwritten by the primary text, making areas difficult to read.
