of electronic information in the last quarter of the twentieth century brought a new era of library operations and services, with the ability to access information resources beyond those available in the physical facility. As early as 1973, the Library began to take advantage of electronic information services by acquiring the New York Times Information Bank, the first computerized online information retrieval service. By the 1990s, the library was able to access thousands of U.S. and foreign newspapers and magazines, highly specialized biographic and subject information, and U.S. government and think tank documents through commercial and government databases. Organizational home Throughout its history, the library was moved not only physically, but also administratively. In 1833, for example, a Bureau of Pardons and Remissions and of Copyrights was created and charged with various duties including the "arrangement and preservation of books, maps, and other documents and of keeping an accurate catalog." In 1834 the bureau was abolished and its library functions were transferred to the Office of the Translator and Librarian and then to the Home Bureau in 1836. Throughout most of the nineteenth century, the library was administratively located in the Bureau of Rolls and Library, which managed the library, books, documents, orders, laws, and treaties. In 1872, a Division of Indexes and Archives was created to distribute, file and index the Department's correspondence, open the mail, preserve the archives, and retrieve requested papers. An Act of 1874 placed the library administratively side by side with the Department's Archives under the Chief of the Bureau of Rolls and Library. In the 1920s, the library became a branch of the Historical Division, and in 1948 it gained independent status as a Division in the Office of Libraries and Intelligence-Acquisition. In 1973, the library became one of the divisions in the Foreign Affairs Document and Research Center, which brought the library and document activities back together. Rare books and incunabula The Library contains a number of rarely held historical works, which reflect the Library's existence from the earliest days of the federal government. Two books are especially valuable because they are known to have Thomas Jefferson's signature—the Corps Universel Diplomatique and Histoire Des Traites De Paix, published in Holland in the 1720s, both of which managed to avoid destruction in the fire of 1814. These two volumes, along with other rare books in the Library's special collection, have been restored with repairs,
