The first edition of this classic dictionary was published more than a hundred years ago in 1901 and it has been the "Great Gaelic Dictionary" ever since. Instead of a lithographic reproduction this edition is newly typeset. This has allowed us to increase the font size slightly and, as a result, the text is much clearer than ever before. Small things were adjusted: typos, errors in the alphabetic ordering and the orthography has been tweaked a wee bit regarding some inconsistencies. The illustrations were digitally cleaned and they too are now much clearer, especially the numbering on the more complex illustrations. No new terms have been added, so it's "Dwelly virtually the way he always was but easier to read."
