The web is a powerful tool for artists and writers. It allows them to offer fiction, poetry, and the visual arts to the public in a matter of hours, without the intervention of literary agents, publishers, or gallery owners, and at virtually no cost to anyone. There are many possible uses of the web for research. One major contribution is likely to be the publications of bibliographies. A couple of examples included on your list are the bibliography of Medieval Spanish history from the University of Central Arkansas, and Mary-Anne Vetterling's astonishingly huge listing of resources for the Libro de buen amor .
Electronic journals are another exciting possibility.
Interletras , from the University of Zaragoza, is a good example of what can be done. Other journals, such as Celestinesca, have home pages with indices, but the articles themselves are only accessible in print. My guess is that until universities recognize the value of electronic publications, which can be refereed in the same way as print publications, this area will continue to lag behind the others. Once this happens, however, the cost of publishing critical materials will be significantly reduced, and there could be an explosion of materials available to scholars. Perhaps the most promising service the Web can offer researchers is that of a provider of texts.
