The Southborough Library is planning a new space dedicated just to “tweens and teens,” and library officials are seeking advice from their target audience. They have put together an online survey to help determine why young adults do (or don’t) use the library, what features and services they would like to see more of, and what general aesthetic would most appeal to them. Residents between the ages 11 and 18 are encouraged to take the survey, which can be accessed by visiting the teens page on the Southborough Library website, www.southboroughlib.org, or the Southborough Library for Young Adults page on Facebook.
