‘Rings’ trilogy in single volume

To mark the 50th anniversary of the U.S. publication of “The Lord of the Rings,” Houghton Mifflin is offering a new deluxe one-volume edition of J.R.R. Tolkien’s classic fantasy trilogy.

The leather-bound, slipcased volume has gilt-edged pages and a ribbon bookmark. Inside are two fold-out maps and a four-page color insert showing leaves from the story’s “Book of Mazarbul.” Appendixes contain family trees, a chronology, calendars, and a writing and spelling guide. There are separate indexes for characters, places, things, and songs and verses.

The commemorative edition contains more than 1,000 pages and sells for $100.
