Sir John Lavery (1856-1941): Spring in a Riviera Garden [detail; 1921; Sothebys]
As ever, the best place to start is Art UK, which has 389 paintings by John Lavery that are in public collections. I’ve put them in date order: here. When you click on an image that interests you, scroll down as there is often a link to the Gallery’s website with further detailed information.
Then Christies [here], Sothebys [here] and Bonhams [here] not only have fabulous images of paintings that are in private hands (and have been to auction), but usually when you scroll down there is a fully-researched catalogue essay.
The Ulster Museum website has a good introduction to John Lavery [here], and Kenneth McConkey has written about Lavery’s seascapes on Art UK [here].
Indeed Kenneth McConkey is the authority on John Lavery as curator of exhibitions and writer of catalogues, including:


John Lavery: Diary of a Painter [2010; Publisher: Atelier Books; ISBN: 9781873830215]
and Lavery on Location [2023; published by National Galleries of Ireland; 9781911716020] which is from the most recent Lavery exhibition and there’s a podcast/film “In Conversation with Kenneth McConkey” on YouTube [here].
With hope these might be useful starting points!
