This is the introduction to a four part series of books. They are:
Part I, with a separate book of keys to the exercises,
Part II,
Part III,
Part IV.
There are two auxiliary books in the series,
Dia, Diabhail agus Daoine, and,
Trí Seoda Ó Albain,
Making a set of seven books in all.
Only the Introduction and Part II have been re-typeset. The rest only exist is image files. I will issue Part I and its key as a trial image file.
Re-typesetting is a big job. I will see if I can find some time.
