Americana refers to artifacts, or a collection of artifacts, related to the history, geography, folklore and cultural heritage of the United States. Many kinds of material fall within the definition of Americana: paintings, prints and drawings; license plates or entire vehicles, household objects, tools and weapons; flags, plaques and statues, and so on. Patriotism and nostalgia play defining roles in the subject. The things involved need not be old, but need to have the appropriate associations. The Atlantic described the term as "slang for the comforting, middle-class ephemera at your average antique store—things like needle-pointed pillows, Civil War daguerreotypes, and engraved silverware sets." The term may be used to describe the theme of a museum or collection, or of goods for sale.
The term can also be used to describe studies of American culture, especially studies based in other countries. Americana music is contemporary music that incorporates elements of various American roots music styles, including country, roots-rock, folk, bluegrass and blues, resulting in a distinctive roots-oriented sound.(Wikipedia)
