New Addenda and Corrigenda for the “now so big, it’s square-shaped!” new edition of the J.R.R. Tolkien Companion and Guide.
If your letter box and/or wrists can’t quite cope with such hefty slabs, I see there are now Kindle ebook tablet editions of the 2017 edition. Although these don’t show up as links from Amazon’s hardback/boxed-set page. Here are the links to the ebooks:
* Volume 1: Chronology (£24)
So £53 for the lot. Not bad, and on the Kindle these are also keyword-searchable to boot (albeit individually, rather than all three at once — I know of no tool that will index across multiple .mobi files, even they were to be DRM free).
What is the difference between Reader’s Guide – PART 1 and PART 2? The publisher’s description is useless on that point. But thankfully there’s a view of the Contents page on Google Books:
Apparently the Index in Vol. 1 and Vol. 3 are both duplicates of each other, and presumably they refer to the pages of the print version.
