The event, which celebrates National Library Week, will include tours for patrons of all ages and a rare opportunity for a behind-the-scenes look at bookmobile operations. During the visit, the traveling branch will offer story times for younger children, giveaways and an appearance by Sneaks the Cat, the system's mascot. All library materials will also be available for check-out. The North Point Branch is located at 1716 Merritt Blvd in Dundalk. Information: 410-887-7586.
