David Day is a prolific Canadian author who has written several Tolkien-related books. Primarily known for his reference books, starting with A Tolkien Bestiary in 1978, Day's books have been published in over 120 different editions in over 20 languages.
Day's books have been repeatedly criticized by the Tolkien community for their inaccuracy. Day rejects the charge of inaccuracy, though he accepts that his reference books have been repackaged and reprinted by publishers under different titles.
 Popular artbooks
David Day's Tolkien works are popular (rather than scholarly) works that include lot of art that are more appreciated by a popular audience still grasping the world and characters.
These books have sold over 3 million copies worldwide.
Artists featured in the books include Victor Ambrus, Jacopo Ascari, Graham Bence, Jaroslav Bradac, Tim Clarey, Allan Curless, Gino D'Achille, David Franklin, Melvin Grant, Sam Hadley, David Kearney, Barbara Lofthouse, Mauro Mazzara, Ian Miller, Sue Porter, Lidia Postma, David Roberts, Neil Gower, Turner Mohan, Andrea Piparo, Sarka Skorpikova, Jeffery Thompson, Jamie Whyte, Pauline Martin, Andrew Mockett, Kip Rasmussen, Ivan Allen, John Davis, Les Edwards, John Blanche, Rachel Chilton, Sally Davis, Micheal Forman, Linda Garland, Liz Pyle, and Jamie Whyte.
 Reputation within the academic Tolkien Community
The Tolkien Society does not recommend any of Day's books in their suggested readings (preferring Robert Foster's The Complete Guide to Middle-earth instead) whilst David Bratman, editor of the Tolkien Studies journal, makes the same suggestion that David Day's books are "Not Recommended". Troels Forchammer noted in his blog that "Day is infamous in Tolkien circles for his creative re-interpretation of Tolkien's work" whilst Michael Martinez made the sterner observation that "In Tolkien scholarship the worst insult one could deliver at any point for many years was equivalent to 'That sounds like something David Day wrote'."
Tolkien Meta-FAQ author Steuard Jensen said about A Tolkien Bestiary that "it is not wise to rely on this book for information on Tolkien's vision of Middle-earth" and that "it is important to be aware that a considerable number of other details in those vivid descriptions were invented by Day himself with little or no justification in the texts, and that these extrapolations are not distinguished from the justified facts in any way". In particular, A Tolkien Bestiary (and its derivative Tolkien: The Illustrated Encyclopedia) has been specifically criticised for its entries on Beren, Giants, long-worms, Sauron, Telcontari.
Most of the criticism have been to the encyclopedia style books. More recently The Battles of Tolkien has been described saying:
"One of the surprises to me is that this book contains genuinely new content; this isn’t just a rehashing of previous books. And the factual pieces of information on the battles and the characters are accurate: it was a pleasant surprise to me to find none of the painfully obvious errors that were common throughout the previous two books. Similarly, the chronologies – save for one inconsistency on the War of Wrath – were also accurate."
—Gunner, Shaun. "Review: The Battles of Tolkien" in Amon Hen 267
Having acknowledged that the book contains fewer factual errors than earlier books by Day, the reviewer describes it as "not a work of reference, but an attempt at analysis" and describing the analysis as "a bunch of clichéd theories that failed to stretch beyond a child pointing at things and exclaiming 'This is like that!'."
 A Composite Study Of The Lands Of Arda Throughout The Ages
A Tolkien Bestiary (1979) and later works includes a map that intentionally gives an overall view of all the lands over all the ages in a composite image. It include the Lamps, the Trees Of The Valar, Númenor, Beleriand, and the Undying Lands which never existed all at the same time. The map is criticized for differences from Tolkien's own maps such as "Map V" from the Ambarkanta maps.
 Oxonmoot controversy
Chris [Chris Crawshaw, Chairman] has also written to David Day to ask him to pay his registration for Oxonmoot. She was instructed by the meeting to keep badgering him about this, since he seems to feel his 'celebrity' status exempts him from such mundane details
—Amon Hen 191, p. 19
Four months later in the minutes of a committee meeting held on the 26th February 2005 it is recorded:
Since David Day has still not paid his registration for Oxonmoot, it was agreed that he should be blacklisted for future events.
—Amon Hen 193, p. 17
There are no other recorded incidents of The Tolkien Society blacklisting individuals from attending their events.
