Ériu, a journal from the Royal Irish Academy, has published a special compilation issue in honor of the International Conference of Medievalists. The articles are all reprints, but they are some stellar reprints, and you can read them or download the .pdfs without a subscription to Ériu. The complete table of contents contains links to download .pdfs of the articles. Here are some that are particularly noteworthy: Calvert Watkins — “Sick-maintenance in Indo-European.” Donnchadh Ó Corráin. “The education of Diarmait Mac Murchada.” T.M. Charles-Edwards. “Early Irish Saints’ Cults and their Constituencies.” R. I. Best. “Notes on the script of Lebor na hUidre.”
Celtica, an excellent scholarly journal on Celtic Studies published by the Dublin Institute of Advanced Studies has, for several years, made the more recent volumes available on the web as downloadable and printable .pdf files. Currently the last three volumes are available here. I can’t say enough good things about this endeavor, and the value it offers both advanced scholars and students who may not be able to read Celtica at their libraries. You need a .pdf reader in order to view or print these files. Adobe’s reader is availabler for a variety of platforms, including Mac, Linux, and Windows here at no charge.
