Why this is in the register

HOLLIS on the Latin title returns one record, Patrizia Stoppacci's Clavis gerbertiana (Quaderni di C.A.L.M.A. 3, SISMEL, 2016), catalogued as Italian and Latin and containing the dialogue as one of its items (https://hollis.harvard.edu/discovery/search?query=any,contains,Gerbert%20De%20rationali%20et%20ratione%20uti&tab=Everything&search_scope=MyInst_and_CI&vid=01HVD_INST:HVD2&offset=0 1 record). The general English query for Gerbert returns only an unrelated volume (https://hollis.harvard.edu/discovery/search?query=any,contains,Gerbert%20Aurillac%20English%20translation&tab=Everything&search_scope=MyInst_and_CI&vid=01HVD_INST:HVD2&offset=0 Migne PL 139 prints it as 'Libellus de rationali et ratione uti' at col. 151 (https://archive.org/details/patrologiaecursu0139mign). No English translation of the dialogue was located.

A short dialogue with the emperor Otto on whether 'rational', 'that which is rational' and 'reason' name the same thing - one of the most original pieces of Latin logic written before Anselm, and a document of the education of the Ottoman court. It is short enough that its absence from English is a pure oversight, and an English version would take a translator a few weeks.
