Maryland's public libraries have come a long way since 1902 when the first legislation was passed that established libraries throughout the state. After operating under the State Board of Education from 1935 to 1971, the Division of Library Development and Services (DLDS) was formed and later named the official State Library Agency of Maryland. The DLDS consisted of two branches - the Maryland State Library for the Blind and Print Disabled (LBPD) and the Public Libraries and State Networking Branch (PLSNB). In 2017, the Maryland General Assembly established the Maryland State Library Agency (MSLA) and transferred the duties and responsibilities of the DLDS over to MSLA.
MSLA celebrated its fifth year as an independent agency in 2022, serving over 3.3 million people from 190 library branches across Maryland. MSLA continues to support Maryland's public libraries in their mission to offer outstanding resources, programs, and excellent customer service to all Marylanders.
