Why this is in the register
The only translation of the Liber apologeticus recorded in HOLLIS is the French one inside 'Correspondance, apologétique, œuvres canoniques' (CNRS, Sources d'histoire médiévale 47, 2023), whose summary describes the Apologeticus as 'un traité polémique adressé aux rois Hugues Capet et Robert le Pieux' and prints it with the Latin (https://hollis.harvard.edu/discovery/search?query=any,contains,Abbo%20Collectio%20canonum&tab=Everything&search_scope=MyInst_and_CI&vid=01HVD_INST:HVD2&offset=0 The wider Abbo query produces no English version (https://hollis.harvard.edu/discovery/search?query=any,contains,Abbo%20Fleury&tab=Everything&search_scope=MyInst_and_CI&vid=01HVD_INST:HVD2&offset=0 58 records), and the English Abbo literature catalogued there is biographical and scientific rather than editorial. Migne PL 139 prints the 'Apologeticus' at col. 461 (https://archive.org/details/patrologiaecursu0139mign). No English translation was located.
A polemical treatise addressed to the first Capetians, it is the principal witness to how the most influential monastic intellectual of the age argued with the new French dynasty, and it is the companion piece to the canonical collection. English has a biography of Abbo but not a page of this treatise.
