This is a collection of fourteen original, substantial, commissioned essays dealing with various aspects of Old English and Old Norse manuscript study. The contributors are working in a closely integrated field, which gives the book a unity. The work includes essays on textual editing, codicology, the interrelation of text and manuscript, manuscript backgrounds, and librarianship. Many of the articles develop current scholarly discussions; others discover new manuscripts or reveal unknown relationships or characteristics; several comprise editions of texts or are related to the problem of editorship or translation; and one details the arrangements of the old British Library before its move to St. Pancras. The collection is aimed at manuscript specialists, graduate students working in this or related fields, research librarians, and interested medievalists in early English or Norse studies.
