Other Data Sets.

Textual databases of classic works (out of copyright) and image collections for important artistic exhibits or museums have been assembled by scholars and made available through the Internet. (See [13] for a collection of arts and humanities electronic resources and projects). As more schools and individuals acquire access tools and funds, it is likely that private digital libraries will move out of specialized markets to provide access to primary information for a fee. For-profit companies such as publishers of print, music, and film products and radio and television broadcasters own enormous volumes of information, and international information infrastructures will create new markets for that information. Teachers and learners will likely not be heavy on-demand users for this information but rather want to use it as the raw material for study and for integration into instructional presentations. How these materials are made available and what "fair use" policies evolve are yet to be determined.
