While there have been changes made to the Norton Anthology of English Literature, Volume 1 (or A), there's no mistaking that in its genre, this is a masterpiece. It's easy to quibble with which selections make it in and which versions are used, etc. But this is an incredibly rich resource of early English literature.
This is one of the books that helped foster my love of literature, and that of many others. It is a portal to any number of authors you wish to read in more detail. It's hard not to love a book that gives you introductions to the following authors and works - and many, many more!
Bede and Beowulf
The Anglo-Saxon Chronicle
Sir Gawain and the Green Knight
Chaucer's Canterbury Tales
Julian of Norwich
Thomas Mallory and the Arthurian Legends
Sir Thomas More and Utopia
William Tyndale, John Calvin, John Foxe
The Book of Common Prayer
Spencer's The Fairie Queene
Sir Walter Raleigh
Many of Shakespeare's sonnets and 2 of his plays
And John Bunyan
The Norton Anthology series does exactly what it should: introduce its readers to a smorgasbord of the best of English literature. Don't let the size or price daunt you. The size is worth it for the breadth and depth of content. As for price, there are many inexpensive used editions around, going back to many earlier editions.
This book should be on every bookshelf!
