Tolkien’s Library: An Annotated Checklist

Tolkien's Library: An Annotated Checklist is an in-depth scholarly study and reference work by Oronzo Cilli, published in 2019. The work aims to establish a complete list of books that once existed on J.R.R. Tolkien's shelves, which he either read, owned, borrowed, or consulted.

Though not designed for ordinary reading, the book is welcomed by scholars for providing a guide to Tolkien's mind and pointing out directions for future studies. It was the winner of the Best Book award of the Tolkien Society Awards 2020, and a finalist for the Mythopoeic Scholarship Award in Inklings Studies 2021.

The main checklist contains some 2600 entries, which forms the bulk of the book. Also included here are: a list of Tolkien's published writings in his lifetime; his interviews and reviews; student papers that he examined; publications by the Early English Text Society when he was a member; and his lecture schedules in Leeds and Oxford.

A second edition of the book was published in 2023, with addition of more than 400 new entires, an afterword by Verlyn Flieger, and a newly discovered poem by G.B. Smith not included in A Spring Harvest.
