As of 2018, 40 further editions of Gray's Anatomy had been produced since the first edition.

Notes on verification

Corroborated by Wikipedia and Elsevier publication records showing 1858 first edition and 41st edition in 2015, consistent with '40 further editions' by 2018. Original phrasing closely follows a single blog source, but underlying facts are independently verifiable.
