Nancy Edwards 
The Archaeology of Early Medieval Ireland [PDF ebook] 

In the first major work on the subject for over 30 years, Nancy Edwards provides a critical survey of the archaeological evidence in Ireland (c. 400-1200), introducing material from many recently discovered sites as well as reassessing the importance of earlier excavations. Beginning with an assessment of Roman influence, Dr Edwards then discusses the themse of settlement, food and farming, craft and technology, the church and art, concluding with an appraisal of the Viking impact.

The archaeological evidence for the period is also particularly rich and wide-ranging and our knowledge is expanding repidly in the light of modern techniques of survey and excavation.
