The Mutopia Project offers sheet music editions of classical music for free download. These are based on editions in the public domain. A team of volunteers typesets the music using LilyPond software.
State Law Enforcement. There are 66 state-level law enforcement agencies in the United States designated as state police, highway patrol, or state investigative departments. Most state police organizations were created between 1900 and 1930 and were primarily deigned to suppress the organization of labor unions.
A national law enforcement agency is a LEA in a country which does not have divisions capable of making their own laws. A national LEA will have the combined responsibilities that federal LEAs and divisional LEAs would have in a federated country. National LEAs are usually divided into operations areas.
