The hard times independent booksellers have fallen on over the last decade can probably be traced back to Seattle. This is, after all, home to Amazon which got its start disrupting the world of book retail.

But the time-honored brick-and-mortar bookstore is a hardy institution, one that even Amazon came around to, opening its own first physical bookstore in (where else?) Seattle. In fact, bookstore sales actually started increasing again in 2015 after a period of decline.

This Saturday, independent bookstores around the city are hosting a celebration of that resilience and their role as a hub for readers.

Seattle Bookstore Day is taking place all day Saturday at 19 bookstores around the city. The stores will host parties, give away merchandise, and offer discounts. Guests can pick up a “passport” at any of the participating stores and those who get stamps from each location will receive 25 percent off at all stores for a year.

Participating bookstores and links to their events are listed below.

Eagle Harbor Book Company

Elliott Bay Book Company
