Few of the writings on the more modern history of Ireland, written in the period between the union and the granting of emancipation, may be said to have been the result of original investigation. Neither from the standpoint of sources nor from the manner of presentation were there any obvious signs of development. The general histories by Gordon, Burdy, Taaffe, Lawless, and the rest relied for their facts upon general histories written in the eighteenth century, such as Leland, Warner, Hume or Curry, or upon the authorities cited in these and for the most part re-edited during our period—such as Cambrensis, Spenser, Keating, Ussher and Ware. Indeed, very often the general historians were only too content to rely solely on each other. Thus, Lawless (1814) was greatly indebted to Taaffe (1811), who, in turn, had leaned upon Plowden (1803). And Burdy (1817) was, for all practical purposes, a re-edition of Gordon (1805), even to the very sentences and marginal indications of the contents of paragraphs.
