FAIRFIELD — The town has booked a new librarian.

Helene R. Murtha, who for the past year has been the head of Children’s Services for the Fairfield Public Library, was chosen to lead the library system. Murtha was chosen after the library board of trustees conducted a national search.

First Selectman Mike Tetreau announced that after an extensive national search, Murtha was selected to serve as town librarian, effective Monday.

Before coming to Fairfield, Murtha was the school library media specialist for the Eastchester Union Free School District in Eastchester, N.Y. She has also worked as the children’s librarian for Yonkers, N.Y.

“As a Fairfield University graduate, I was thrilled to return to Fairfield last year as head of Children’s Services at Fairfield Public Library,” Murtha said. “The town and the library hold a special place in my heart, and I am excited to collaborate with the first selectman, community officials and organizations, board of library trustees, Friends of Fairfield Public Library and library staff to work together to continue to build on and enhance Fairfield Public Library’s long history of providing quality services and programs for the community.”

Murtha received a bachelor’s degree in business management, and a master’s in library and information science from Fairfield University. She received a doctorate in educational administration from Dowling College and certifications in teaching and library sciences from the state of New York.

Murtha, 54, will make $120,000 in her new job.

The search for a new librarian began in May, when Karen Ronald retired. With the assistance of a search firm, the library board reviewed 31 candidates, and interviewed six semifinalists and three finalists before choosing Murtha.

Her work in schools and children’s services make her the perfect fit to be the Fairfield Public Library’s town librarian,” said Sonal Rajan, chairman of the library board. “The board anticipates working closely with Dr. Murtha, the staff, the Friends of Fairfield Public Library and community stakeholders to build on the library’s solid foundation, and develop collaborative partnerships with the town and other local agencies and organizations.”

Margo Kaminsky, president of the Friends of the Fairfield Library, said they are delighted to welcome Murtha in her new capacity. “Her background and experience make her uniquely qualified to lead our library system into the future.”

“I am thrilled to welcome Dr. Murtha as Fairfield’s new town librarian,” First Selectman Mike Tetreau said. “Dr. Murtha’s outstanding performance as head of Children’s Services and her intimate knowledge of our public library system will serve our community well. I look forward to working with her to continue to meet the needs of all of our patrons who frequent our fine libraries.”
