Nearly everyone can name titles written by J.R.R. Tolkien. Often considered the father of modern fantasy, it’s no surprise that his works are well-known and well-loved. Whether fans have read his books or watched the film adaptations, Tolkien’s Middle Earth and its inhabitants have infiltrated 20th and 21st century culture to an astounding degree. For collectors of the great British author, information and works about his own life may prove to be both satisfying and necessary additions to a Tolkien Library. Where should you begin if you’re looking to add to the books in your collection? It makes sense to start with his letters. Tolkien wrote a vast number of letters. Fortunately for collectors, a compilation was put together by biographer Humphrey Carpenter.
