As regards the texts, my chief debt is to the Chaucer Society, which means, practically, Dr. Furnivall, through whose zeal and energy so many splendid and accurate prints of the MSS. have been produced, thus rendering the actual readings and spellings of the scribes accessible to students in all countries. It is obvious that, but for such work, no edition of Chaucer could have been attempted without an enormous increase of labour and a prodigal expenditure of time. Next to the MSS., the only authorities of any value are a few of the earliest prints; viz. those by Caxton, and (in the case of the Envoy to Bukton) by Julian Notary; and the editions by Thynne and Stowe. Thynne's text of the Book of the Duchesse is, in _one_ passage, the sole authority; and his text of the Romaunt of the Rose is, not unfrequently, correct where the Glasgow MS. is wrong. His text of the House of Fame is also valuable, and so is that of Caxton; and the same remark applies to some of the Minor Poems. Both Caxton and Thynne furnish very fair texts of Boethius. Thynne's version of Troilus follows a good MS., and is worth collation throughout; but his Legend of Good Women follows a MS. of a very poor type, and his Treatise on the Astrolabe is decidedly bad. Very little help is to be got from Thynne as regards the Canterbury Tales; indeed, it is the chief fault of Tyrwhitt's text that he trusted far too much to the old black-letter editions. Stowe's edition of 1561 is useful in the case of A Complaint to his Lady and Words to Adam. Otherwise, it may usually be ignored. As regards later editions, I am most indebted to the following. To Dr. John Koch, for his edition of the shorter Minor Poems, viz. those which in the present edition are numbered as I. VIII. IX. X., XIII-XVII., and XIX. His text is excellent, and there are numerous notes. He has also written several important criticisms in Anglia, besides a detailed examination in Englische Studien (xv. 399) of my own edition of the Minor Poems, published in 1888. To Dr. Max Lange, whose dissertation on the Book of the Duchesse is careful and useful.
