The $10 million renovation of the Jamaica Plain Branch of the Boston Public Library revitalized the branch services and spaces, including a 20 percent increase in space for the community to read, browse the book collection, access computers, attend and host meetings and participate in programming.

Patrons will be able to enjoy artwork by Belmont photographer Steven Edson during May and June. Edson is one of four artists chosen from 50 applicants whose work will be on display at the library this year. He captures abstract selections of paint found on city streets, boiling them down to an essence of line, shape and color. Each photograph carries multiple levels of interpretation, whether viewed literally, figuratively or abstractly.
