The Rockport Public Library is celebrating its centennial with a community celebration Friday, May 30, from noon to 5 p.m., and the public is invited to help library staff and friends mark the occasion.

The Rockport Public Library began as a roomful of books in the basement of the Rockport Opera House in 1914. Since then it has grown and expanded under the leadership of only six directors, most recently Molly Larson of Hope. Today the library offers not only books and magazines but also computers, music, ukuleles, DVDs, puzzles, Kindles, eBooks, and Interlibrary loan service. Housing a collection of more than 32,000 books in its Rockport building, the library boasts a circulation of more than 67,000 titles each year.

The library also hosts a wide variety of programs for adults and children, from Storytime for babies and toddlers to a long-running French conversation group, to several book and writing groups. All library programs are free and open to the public.

The 100th anniversary open house begins at noon at the library (1 Limerock St.). Highlights of the day will include a variety of children’s activities, jazz groups from the Camden-Rockport Middle School and Camden Hills Regional High School, the CHRHS OffBeats a cappella group, a raffle for a Kindle Paperwhite, giveaways, and fun. Handmade cheeses by Lakin’s Gorges Cheese and cupcakes from Laugh Loud, Smile Big will be available as well.

The celebration is made possible by a donation from the Friends of the Rockport Public Library.
