PHILADELPHIA (WPVI) -- The Philly Bookstore Crawl is happening Saturday. It's like a bar crawl, but instead of liquor it's all about literature!
It's a self- guided tour, featuring more than 50 independent bookstores across 18 different neighborhoods.
This years' event marks the 4th year of the crawl.
Each store is offering its own special activities including giveaways, discounts, author signings and more.
