Who we serve

The State Library was established in 1826 to collect, deposit, and house the Commonwealth's collections of maps, statute books, and government documents in a single central location. Since that time, the State Library has grown into a multifaceted and reliable resource for legislators, executive personnel, state employees, historians, genealogists, and users from all over the world.
