One of the established purposes of HETHS is to establish a library and that library and archive was brought to Hershey in 2013. The HETHS archives contain sales literature, dealer promotional material, shop manuals, photographs, owner’s manuals, drawings and more. Descriptions of all of the HETHS holdings can be found in our online catalog and accessed on site in Hershey.
