General Websites
These are just a few of many websites that will lead you to useful and reliable information on Italian language and literature. These are "gateway" sites, i.e., lists of links to many other sites rather than "end destinations" in themselves.
Europeana is a really good place to start exploring. It has millions of items—books and manuscripts, photos and paintings, television and film, sculpture and crafts, diaries and maps, sheet music and recordings—from a range of Europe's leading galleries, libraries, archives and museums.
