This is a bibliography of post-graduate theses on language and linguistics in Irish university libraries, from 1915 to 1976. The 537 entries are listed by author and indexed by subject and language. In addition, each entry contains the following information: degree, year, and university. An appendix contains theses completed outside of Ireland which are of interest because of subject matter or authorship. This volume is intended to assist those engaged in the training of language teachers and to give a general picture of research carried out in Ireland in the field of language. Although the list is not considered complete, an effort was made to include all theses thought to be in any way relevant to language and language teaching. Excluded are works on literary appreciation and literature in general, except where it was thought the work might yield information on language or the history of a particular language. (Author/AM)
