We adore home libraries so much, we're revisiting them once more. (Check out properties we found earlier this year that featured them.) For bookworms out there, now's a great time to apartment-hunt, given the selection of shelf-lined properties available on the market. And no surprise: To borrow the name of a local literary festival, New York is book country, after all.

Believe it or not, that’s not the living room of this oversized two-bedroom co-op at 870 United Nations Plaza (yours for $6.8 million). It’s a 718-square-foot private library.

This four-bedroom, two-bath duplex at 130 Jane Street for sale at $2.995 million is a book lover’s dream thanks to a quiet windowed office-library featuring a full wall of floor-to-ceiling built-ins. It’s up to the new owners to set up their own Dewey Decimal system.

Some entranceways are lined with closets or coat hooks, this one at 284 Lafayette (on sale for $4.995 million) boasts floor-to-ceiling bookcases that create a welcoming environment no ordinary foyer could ever match.

A sliding ladder makes reaching the volumes on the top shelf of this wall-to-wall bookcase a cinch. Given the library’s location right next to the gourmet kitchen in this $4.2 million Tribeca loft, we’d expect at least a bay or two devoted exclusively to cookbooks.
