I this post, I'm going to give a rundown of the Tolkien books coming up in the next while worthy of note.
First up, as I previously reported, is what will most likely be this year's main Tolkien event, the publication of Beren and Luthien. It will be available in hardback and deluxe edition formats.
Also, coming out, is Hammond + Scull's revised edition of their Tolkien Companion and Guide. It will be 3 physical books total, with the Reader's Guide being split into two. The ISBN for this set is 9780008214548.
There will also be a sketchbook of John Howe's artwork titled A Middle-earth Traveller, with an ISBN of 9780008226770.
David Harvey's book about Tolkien, myth, and Middle-earth, The Song of Middle-earth, will be publishing in a print-on-demand hardback from tolkien.co.uk with an ISBN of 9780008184834.
Finally, for 2017 that is, Jemima Catlin's colour illustrated edition of The Hobbit in paperback is arriving in September, just in time for The Hobbit to turn 80. The ISBN of that edition is 9780007497935.
Next year sees the paperback edition of The Story of Kullervo, which will match the other Tolkien paperbacks in terms of size dimensions, so they'll be 'level' on a book shelf. The ISBN for that edition is: 9780008131388. In 2018, it's possible that the paperback edition of Beren and Luthien should also be out as well. No listing yet, however.
Finally, there will also be a paperback edition of A Secret Vice publishing in early 2019. The ISBN for that edition is 9780008131418.
I will conclude by saying that there could very well be other Tolkien books announced. Some publication dates could change, as well. I'm also keeping a lookout for any possible listings of a deluxe edition of The Lay of Atrou and Itroun, but there's been nothing thus far. The books mentioned are the ones that I believe deserve mention and attention. There could be some others, but not enough is known at this point (example: "A Middle-earth Treasury", which I'm fairly certain will be pocket hardback editions of The Hobbit, The Fellowship of the Ring, The Two Towers and The Return of the King in a set very similar to "The Tolkien Treasury")
