Rated 5 out of 5 stars
BookBurro is great for college students seeking textbooks or anyone else who shops for books. Even people who never buy a book will want this extension with the handy library search function. Surprisingly, I didn't find my library on the extensive list. However, the developer responded to my email quickly, adding support for my library within a day!
Great extension with great support. Should be on everyone's list of installed add-ons!
