My favorite part of my apartment is my wall-length bookshelf. When I look at it, I think of all the time I spent reading and accumulating its contents. I feel I’ve earned it, which is why I’m slightly insulted by Juniper Books’ $3,000-$100,000 “collection-development service,” a program designed for “people who want a library but haven’t had the time or inclination to amass a collection of books.”
