The following book is another good beginning read. I say beginning because I would consider it a primer into the content to the Nag Hammadi Library. It is not bogged down with a lot of scholarly commentary (in fact it has none other than an introduction) or historical data. It is simple and clear and contains many of the popular Gnostic pieces. The translation is meant to be understood by the layperson. In my opinion, it has a very nice flow, giving the newcomer to Gnosticism a reasonable understanding of these scrolls / codex. It includes The Gospel of Thomas and The Gospel of Mary Magdalene.
