In the 1980s, UMI began producing CD-ROMs that stored databases of periodicals abstracts and indexes. At a time when modem connections were slow and expensive, it was more efficient to mail database CD-ROMs regularly to subscribing libraries, who installed the discs on dedicated PCs. The ProQuest brand name was first used for databases on CD-ROM. An online service called ProQuest Direct was launched in 1995; its name was later shortened to just ProQuest.  The bibliographic databases are mainly sold to schools, universities and libraries.
The Historical Society has a nearly comprehensive collection of newspapers for the state. Kansas residents can borrow newspaper microfilm by placing a request with their local library for an interlibrary loan . Many newspapers dating from 1854-1922 are also online and free for Kansas residents to use via the links in this database. For current non-electronic titles not yet on microfilm, consult our online catalog, ATLAS . Out-of-state researchers should contact KSHS reference staff for more information.
