text with the manuscript again. The outcome of all this is that in
comparison with the first edition there are a few different readings,
some new emendations, and a rather larger number of different
interpretations of particular words and passages. ¹

The bibliography has been altered, but remains highly selective.
It is designed to guide the reader to reference books that will help
him to understand the poem in its setting, and to editions of texts
referred to more than once in the notes. In recent years the flow
of articles on the poem has grown to a flood, and any bibliography
of them would be out of date before it was printed. Only books
are therefore given, and the numerous current bibliographies must
be consulted for the rest. For work up to 1940 Gollancz's biblio-
graphy is excellent.

My thanks are due to many colleagues for suggesting revisions,
and especially to Mr. C. A. Robson for invaluable help with the
Old French forms in appendix and glossary. I salute, forbe al
Ƿyng, Professor Tolkien's fraunchyse and felaȝschyp in letting this
be done to his book.
