Books pile up in my home whenever I get on a weird pseudo-reasearch-y kick, and I am blessed with an indulgent partner who just keeps buying me more bookshelves instead of telling me to cut it the hell out, which is very sweet of him, but also I could really use someone to stop me before I commit more Irresponsible Spending Crimes... though I saw someone the other day comparing book-buying to wine-buying, e.g. hey it's valid and normal to let some of them age in the cellar & have more than you'll be able to drink; you want to have good wine when the time is right! and UNFORTUNATELY this is very effective for allowing me to continue in my profligate ways.

I have the same problem(?) and my partner just says, very patiently: "yes, but the next bookshelves are going in your room, not the living room". :D And sometimes gets to obscure-ish research books long before me, which is always a little funny.

I enjoyed the write-ups of the theology books.
