Adelson is an internationally recognized authority on John Singer Sargent, and he initiated scholarship on the John Singer Sargent Catalogue Raisonné in 1980 in partnership with the artist's great-nephew, Richard L. Ormond. The first seven volumes of the Catalog Raisonné have been published by the Yale University Press. The two final volumes will follow, vol. 8 in 2014, and vol. 9 in 2016.
