About The Oxford Companion to the Book, this review says “This colossal new encyclopaedic Companion has something to say about almost everything that matters in the world of writing, printing, publishing and book-collecting….not just the history of print, but also the history of manuscripts, libraries, bookselling and book-editing. Dozens of experts have contributed, submitting long essays on general topics or short reference entries. The result is an extraordinary tour de force, a cornucopia of bookish information.” It’s 2 volumes, 1048 pages and costs over $250 on Amazon. You can read excerpts here.
