Thanks so much for the review. It's a shame they didn't make it a 4 volume set. However I'll only be using these for reference pretty much, so the readability isn't the end of the world. This is the kind of set you need to consider buying if you ever want to publish your own magic book, so your references are accurate.
If you want a collectors item and some classic routines and a ton of reference points for most of the routines being published nowadays yes. If you are purely looking to just learn and perform material from the book without any of the above, probably not…
