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.”
