Federal land titles from 13 states are being moved to CD-ROM as part of a project designed to preserve the historic documents, according to a recent article in Government Computer News.

The task, which the Eastern States Bureau of Land Management expects to complete by the year 2000, involves states west of the Ohio River where the government sold off public land to repay Revolutionary War debts.

Some 260,000 land patents from Alabama are due to be published next month. Arkansas, Florida, and Louisiana have already been completed. Others on the list are: Illinois, Indiana, Iowa, Michigan, Minnesota, Missouri, Mississippi, Ohio, and Wisconsin.

The records have a reported conversion accuracy rate of 99 percent with 99.5 percent index accuracy.
