This has LWB and other Thoth texts?

If you go trump by trump, there are options to read texts that have to do with the card. I believe it is quoting from the Book of Thoth. The screen "dissolve" effect can be a little surprising for a second or two, but it's worth hanging in there to get the information. If I cannot look up my LWB or texts, this is a good reference for me.
Hope it helps.
I also found Rachel Pollack's Illustrated Guide gave some nice background on the Thoth deck. Her list of astrological assignment to majors for Thoth is a pretty reference table.
She also compares the Haindl with other decks more than a few times in this book...I realize that she's reviewed many decks and likes her own as well. So I see Haindl, Rider Waite, Thoth, Shining Tribe, Ukiyoe, Mythical and others appearing quite a few times
