There are, as one might expect for so popular a subject, a huge number of books on the Celts. In offering some suggestions on further reading I have, of necessity, been very selective, limiting myself to no more than four titles under each broad heading. I have chosen works published in English each offering a lengthy bibliography which, if thoroughly persued, would provide a lifetime of entertainment. I have omitted all those, however attractively produced, that rely on tertiary sources and have little themselves to add. Needless to say the ‘lunatic fringe’ has no place here!
