The Windows release of Bookshelf added a number of new reference titles, including "The Concise Columbia Encyclopedia" and an Internet Directory. Other titles were added and some were dropped in subsequent years. By 1994, the English-language version also contained the "Columbia Dictionary of Quotations"; "The Concise Columbia Encyclopedia"; the "Hammond Intermediate World Atlas"; and "The People's Chronology". By 2000, the collection came to include the "Encarta Desk Encyclopedia", the "Encarta Desk Atlas", the "Encarta Style Guide" and a specialized "Computer and Internet Dictionary" by Microsoft Press.
