Two recently published Lindsay-related essays:

Mark Valentine's latest collection of essays, Borderlands and Otherworlds, includes "'Striking a New Line': David Lindsay's Sphinx". It is available in hardback and ebook from Tartarus Press.

A 2025 academic essay, "Gender and Reality in A Voyage to Arcturus" by Jannicke Meijner, is available via Stockholm Univeristy's website. A interesting essay on the (surprisingly rarely-addressed) topic of gender/sex in A Voyage to Arcturus, it argues that Lindsay "for all his late Victorian puritanism and his anxious relationship to women and sexuality, can be read as a precursor of sorts to queer theorists like Butler, and that he broaches subjects that later become important in feminist science fiction."

A Korean translation of A Voyage to Arcturus came out in 2020, from the publishers Moonhak. Translated by Kang Joo-heon, it seems to have only been published in paperback. The book's page at the publisher's website can be found here.
