Books about books and reading are not every reader's cup of tea, but we have a good many of them and they get a fair lot of use. The subject heading Books and reading--United States pulls up a selection; or try these ; or books about book groups, or book collectors, or owning a bookstore; or very particular reading programs like Phyllis Rose's The Year of Reading Proust. Or 'best books' books like Eleanor Gehres' The best American novels of the twentieth century still readable today (great title!).
Maybe this kind of thing works for you, and maybe it doesn't. But we do know that by far what our users read the most of are novels--general fiction, classics, mysteries, and their cousins. Adult fiction is about 25% of what we own, and more than 30% of circulation, and that doesn't even include authors like Louisa May Alcott (yes, Little Women is on Smiley's list), Patricia MacLachlan's Sarah, Plain and Tall, or the Harry Potters, since it was simpler to run the stats on adult books only.
