chace act
Chace Act. Hist. Copyright. An 1891 statute giving U.S. copyright protection to the citizens of other nations that in turn gave a similar degree of reciprocal protection to U.S. citizens. • The Act was invoked by presidential order or by treaty, primarily with European countries. Under the Act’s manufacturing clause, English-language books and other printed matter had to be produced in the U.S. or Canada in order to qualify for domestic protection. — Also termed 1891 Copyright Amendment Act.
