Birchbox. Ipsy. Dollar Shave Club. Subscription box services are all the rage these days. Food, toiletries, beauty products, novelties — you name it, there's a box for it. But what about literary subscription boxes? Do they exist? And are they really worth it?

First off, yes. There are a lot of literary subscription boxes out there, probably more than you realize. The bookish corners of Instagram love OwlCrate and Book of the Month, but what about the Boxwalla Book Box, Peace & Pages, or My Coffee and Book Club?

Literary subscription boxes are as plentiful as those offering cute novelty items and snacks from Japan. Unlike most box services, however, many literary subscription boxes allow you to tailor your monthly shipments to your reading tastes. Some offer just two categories — adult and YA — while others give you children's, paranormal romance, and classics options as well.

Whether you have one, two, or 10 subscription boxes, you'll always be tempted to tack on another fun postal surprise to your roster. We're not saying you have to sign up for all 14 of these literary subscription boxes, but we're not not saying that, either. Check out the services listed below.

OwlCrate

OwlCrate's themed boxes have taken Instagram by storm. Each month, subscribers get a new YA hardcover, bookish goodies, and handmade items. Past boxes have included Funko POP figurines, tote bags, and magnetic bookmarks. Plans start at $27.99 per month, plus shipping.
