Works with same opus number

[Christopher-dh]

Hello all--

I'm trying to contribute scans of Edwin Lemare's Easter Morn and Concert Gavotte, which are two separate, completely different works that both have the Opus number Op. 121. All other sources state that it's not a printing error; both works indeed have the same opus number, how should I title these two works on the wiki when I upload them?

Since the forum seems very inactive, I just added them on the site with notes in the Extra Information section as following:

https://imslp.org/wiki/Easter_Morn,_Op. ... win_Henry)

Please correct if there's a better way to categorize.

This appears to be one opus number for six pieces: three scherzi and three sets of variations

This is ... very not-uncommon (sorry.) Especially if the works were first published by different publishers and before a point where it was more common for the composers to choose the opus number rather than publishers (consider that this "point" was probably fairly late in the 19th century, or even the 20th century- think Dvorak, e.g. ... Or look at the discussion of Sgambati's worklist.)
