New York and California are examples of states that have statutes requiring all their counties to maintain a public law library. While New York public access law libraries have remained relatively small, the LA Law Library in Los Angeles County is currently second in size behind the Law Library of Congress among U.S. public law libraries, with a collection at just under 1 million volumes, not including digital resources. Public law libraries are available, and in some cases are required, to offer law library and legal research services to the legal community consisting of legislators and other public officials, judges, and lawyers and to the general public, students, and to self-represented litigants. These public law libraries may be affiliated state or local courts. Some academic law libraries provide public access as well, especially in public universities.
