The University of Chicago has launched a digital archive of Roget's Thesaurus, providing researchers and writers with free access to the classic reference work. The project, hosted on the ARTFL Services server, preserves the historical lexicographical resource for modern study. Users can search and browse the thesaurus entries through the university's web interface, maintaining the organizational structure established by Peter Mark Roget in the 19th century.

The digital initiative represents a significant step in making historical language tools accessible to contemporary audiences without subscription barriers. The archive includes the complete thesaurus content, allowing for etymological research and comparative linguistic analysis. This move aligns with the university's broader mission of open access to scholarly resources.
