By Edmund Hogan, revised and corrected by Donnchadh Ó Corráin.
From the Introduction:
This digital version of Edmund Hogan’s Onomasticon goedelicum locorum et tribuum Hiberniae et Scotiae: an index, with identifications, to the Gaelic names of places and tribes (Dublin 1910) is based on (i) the digital version produced by the Locus Project, Dept of Early Irish, University College Cork, under the direction of Professor Pádraig Ó Riain; and (ii) a digital version of the same produced by Stanford University. The Cork text is far superior. The separate files for each letter have been concatenated and typographical errors, where noticed, have been corrected. Where possible, OS standard forms have been used, but this vast task has not been completed. Hogan’s list of abbreviations is highly eccentric, and quite incomplete. I have identified many, but quite a number remain undecoded. Where possible Hogan’s abbreviations have been replaced by more obvious ones. A table is attached (‘List of manuscript and printed sources: current marks and abbreviations’, below). I have made hundreds of additions from my own desultory reading. This digital version was never intended for publication — it is only a personal research tool — but I have been persuaded that others may find it useful that it may save them some time. Note that it has not been properly proofed and I make no claims for accuracy.
