The purpose of the BIAS is, year by year, to draw attention to all scholarly books and articles directly concerned with the matière de Bretagne. The bibliography aims to include all books, reviews and articles published in the year preceding its appearance, an exception being made for earlier studies which have been omitted inadvertently. The present volume contains over 700 entries on relevant publications that were published in 2015.

The purpose of the Bibliography of the International Arthurian Society (BIAS), which continues the annual bibliography previously published by the International Arthurian Society since 1949 as Bibliographical Bulletin of the International Arthurian Society / Bulletin Bibliographique de la Société Internationale Arthurienne (without any interruption in the numerical sequence of annual volumes) is, year by year, to draw attention to all scholarly books and articles directly concerned with the matière de Bretagne. Subjects which are only indirectly concerned with it, such as the origins of courtly love, are deliberately excluded. Also excluded are popular works, general surveys found in histories of literature and most studies which deal with the Arthurian tradition after the sixteenth century. Within these limits, the Bibliography aims to include all books, reviews and articles published in the year preceding its appearance, an exception being made for earlier studies which have been omitted inadvertently.
The research section previously published in BBIAS/BBSIA will be integrated in the new Journal of the International Arthurian Society (JIAS).
