Part 3. Exercise
Question: How long had the Folger Shakespeare Library been standing the year Matus made his trip to England? Passage:Matus would read the history plays together with biographies of the kings they featured, and discovered, from earlier period tourist brochures, an article by A.L. Rowse and one by Louis Wright, past director of the Folger Shakespeare Library, that the artifacts and physical environment of Shakespeare's life were poorly represented. In 1983, impressed by reading a book on English architecture, he scoured the libraries to find information linking Elizabethan buildings to Shakespeare, only to find that virtually no good reference books had been written. After a brief trip to England for roughly 6 weeks in 1984, he and his brother Paul sold their home on Long Island, and Matus used his proceeds to finance his research project on this topic, which entailed a second 6-month journey in a camper vanto examine buildings on-site and interview archivists, preservationists, and historians. Returning to the United States in November 1985, he moved to Washington to finalize his research by reading in the Folger Library. There Samuel Schoenbaum, the doyen of Shakespearean biographers, assisted him in securing access to its restricted collections.
