The building housing the hard copies of the documents is not climate-controlled to prevent the records from deteriorating. The most important records have been relocated to the library's McGrady-Brockman House, formerly a historical center.
Historical collection administrator Brian Spangle says the library has digitized the earliest records dating from the 1790s to the mid-1820s and posted them online.
Documents include marriage records, early will records, probate files and criminal and civil court files.
Some of those files are searchable at visions.indstate.edu.
