If you are on your way to becoming an American citizen, Library for the Blind and Physically handicapped offers Barron’s U.S. Citizenship Test (DB78027).
This audio book presents the procedures and regulations for applying for American citizenship; summaries of U.S. history, geography, and government; and exercises for reading and writing English. It contains the 2013 application requirements and sample forms, questions, and answers. It also includes the texts of the Declaration of Independence and the Constitution.
