• Computers have aided in the study of humanities for almost as long as the machines have existed. Decades ago, when the technology consisted solely of massive, number-crunching mainframe. computers, the chief liberal arts applications were in compiling statistical indexes of works of literature. In 1964, IBM held a conference on computers and the humanities where, according to a 1985 article in the journal Science, "most of the conferees were using compeers to compile concordances, which are alphabetical indices used in literary research."

  Mainframe. computers helped greatly in the highly laborious task, which dates back to the Renaissance, of cataloging each reference of a particular word in a particular work. Concordances help scholars scrutinize important texts for patterns and meaning. Other humanities applications for computers in this early era of technology included compiling dictionaries, especially for forei8n or antiquated languages, and cataloging library collections. Such types of computer usage in the humanities may seem limited at first, but they have produced some interesting re suits in the last few years and promise to continue to do so. As computer use and access have grown, so has the number of digitized texts of classic literary works. The computer-hosed study of literary texts has established its own niche in academia. Donald Foster, an English professor at Vassar College in Poughkeepsie, New York, is one of the leaders in textual scholarship. In the late 1980s Foster created SHAXICON, a database that tracks all the "rare" words used by English playwright William Shakespeare. Each of these words appears in any individual Shakespeare play no more than 12 times. The words can then be cross-referenced with some 2,000 other poetic texts, allowing experienced researchers to explore when they were written, who wrote them, how the author was influenced by the works of other writers, and how the texts changed as they were reproduced over the centuries. In late 1995 Foster’s work attracted widespread notice when he claimed that Shakespeare was the anonymous author of an obscure 578-1ine poem, A Funeral Elegy (1612). Although experts had made similar claims for other works in the past, Foster gained the backing of a number of prominent scholars because of his computer-based approach. If Foster’s claim holds up to long-term judgment, the poem will be one of the few additions to the Shakespearean canon in the last 100 years. Foster’s work gained further public acclaim and validation when he was asked to help identify the anonymous author of the heat-selling political novel Primary Colors (1996). After using his computer program to compare the stylistic traits of various writers with those in the novel, Foster tabbed journalist Joe Klein as the author. Soon after, Klein admitted that he was the author. Foster was also employed as an expert in the case of the notorious Unabomber, a terrorist who published an anonymous manifesto in several major newspapers in 1995. Foster is just one scholar who has noted the coming of the digital age and what it means for traditional fields such as literature. "For traditional learning and humanistic scholarship to be preserved, it, too, must be digitized," he wrote in a scholarly paper. "The future success of literary scholarship depends on our ability to integrate those electronic texts with our ongoing work as scholars and teachers, and to exploit fully the advantages offered by the new medium." Foster noted that people can now study Shakespeare via Internet Shakespeare Editions, using the computer to compare alternate wordings in different versions and to consult editorial footnotes, literary criticism, stage history, explanatory graphics, video clips, theater reviews, and archival records. Novelist and literary journalist Gregory Feeley noted that "the simplest (and least radic A．computers have not been very helpful in humanities study until recently B．computers were widely used in all kinds of literary texts very long ago C．computers were invented by International Business Machines Corporation D．computers began to be used for literary study as soon as they were invented
