Back in May, I signed up for a special treat as part of GiveBIG 2015: a backstage tour of the Seattle Public Library’s Central Branch! The tour was so popular that they needed six sessions to accommodate everyone. When it was my turn, of course I took lots of pictures. So come along with me for a virtual library tour!


All returned books come through this central processing system — including books returned to other branches. The books are checked back in via RFID chip technology as they come off the belt (the column to the left). They’re sorted onto the smaller belts and kicked into sorted bins by pop-up levers. The bins have floor panels that slowly lower as the bin fills, so books don’t fall all the way down and risk getting damaged; it also saves the librarians from having to bend over and reach down to the bottom.

From here, books that belong to the Central branch will go onto carts to be reshelved. Books that belong to other branches will be sorted into different bins and delivered by truck to the branches. The system handles about 1,400 items per hour, so it’s always busy.

I hope you enjoyed this photo tour! You can learn more about the building’s design, LEED Silver rating, and the many architectural awards it has received on the library’s website. Next time you’re in downtown Seattle, stop in for a visit — and don’t forget to check out that conveyor belt.
