The Library provides access for UIUC faculty, staff, and students to several major digitized texts collections. These are available from the Online Research Resources page off the Library Gateway. Because these are subscription databases, authentication is required with a UIUC net id.
In addition to these subscription databases available only to UIUC students, faculty and staff, there are many digital collections available without restriction or cost to the user. Illinois Harvest is a project of the UIUC Library, offering access to digital content about Illinois drawn from dozens of collections. The Illinois Digital Archives, sponsored by the Illinois State Library, also provides access to digitized collections of material about Illinois.
Some other free digital resources to explore are the American Memory Project at the Library of Congress, Women's Travel Writing 1830-1930 and Harvard’s Immigration to the United States, 1789-1930. These are a few of hundreds of digital conversion projects underway at academic institutions, museums, and research libraries.
