What Does It Mean?

I found this list when I was trying to figure out what the Gulag Archipelago had to do with giant sea turtles (see galactagogue). I don't know what it means, but I found it interesting.

If you have read the whole book, bold it. If you have read part of the book, italicize it. If you own it but haven't gotten around to reading it yet, ** it.
