should possibly be merged. The Duo was published in 1920 in the collection ''Tombeau de Debussy'', but then also used as a movement in the Sonata for violin and cello published in composed 1920-1922.
Grove's entry says "Sonata, vn, vc, 1920–22; orig. version of 1st movt pubd in ‘Le tombeau de Claude Debussy’, ReM, i/1–2 (1920)".
I don't know what changes were made that would constitute "orig. version" vs. what eventually ended up in the Sonata (I will have more time to check the two against each other in the next few days but not immediately), but since Grove doesn't list the Duo separately, think it would be better if the Duo movement was put on the Sonata page with comments relating to the two.
Alternatively, since we don't have a work page for ''Le Tombeau de Claude Debussy'', we could create one and deal with it that way, with links between the two.
