The Book Makers: A History of the Book in 18 Remarkable Lives is out in UK paperback in April. You can snap it up at a discount rate at Bookshop.org or Hive (better than you-know-who), or direct from your local independent bookshop. Translations coming soon in Italy, Mexico, South Korea and Japan (‘本の作者たち:18人の注目すべき人生に見る本の歴史’!).
Here is a picture on my kitchen table.
