How to Read a Book has been on my list for the longest time. I might have to finally give it a go. Is the book very dense? I think one of the reasons I've held off is because I have a suspicion that it could probably be distilled down to the length of a magazine article...

I read a decent amount and enjoy it, but I feel in the end I don't get much from it. The time doesn't feel well spent. FWIW, I try to alternate fiction with non-fiction.
