This document is a directory of public libraries in the state of Maryland. Agencies which cooperate with public libraries, such as Cooperating Libraries of Central Maryland, State Library Resource Center, and Public Libraries and State Networking Branch, are also listed. The library entries are arranged alphabetically by county, beginning with Allegany County and ending with Worcester County. Each section of entries typically gives information about the county library or central library headquarters as well as branch libraries. Information ranges from the names of key personnel and trustees to library postal addresses, phone and fax numbers, hours of operation, e-mail addresses, and special services like bookmobile routes. Trustee board meeting times and telecommunication-device-for-the-deaf numbers are also frequently provided. (BEW)
