Point well taken, but I don't think that would stop me from using the program.
To me, printing the books out by Genre would be cost prohibitive. Not to mention the the average guy who's all tanked up at your show, who won't seem to grasp why he can't find Kryptonite, by 3 Doors down in the Country Book, when he knows it was there last week. The average patron I see has a difficult time with just "title" and "Artist".
