Please refer to the list of works by Cui (although someone might have done this with other composers as well): http://imslp.org/wiki/Category:Cui%2C_C ... Antonovich
Someone has gone and changed the main titles for several works -- particularly song collections -- to remove the most distinctive part of the title, in this case usually the name of the poet. There was no good reason to do this. These opus numbers are more easily distinguished from each other by including the name of the poets, ESPECIALLY given that those names appear in the title as the composer published them.
Granted, there are collections of Cui's songs that are as generic as can be and have no such distinction other than, perhaps the French word "mélodies" rather than "romances" -- but unless one knows what makes "21 Poems" (or Op. 62) different from "25 Poems" (or Op. 57) (Nekrasov vs. Pushkin, respectively), this kind of change does a great disservice to the user.
I see that the same thing has been done in the list of Cui's works: http://imslp.org/wiki/List_of_compositi ... %A9sar_Cui
Putting the poet's name in the "Notes" column is no good substitute.
For example, Op. 44 is not
- "20 Poems" ---------------------------------------------------------Note: "after Jean Richepin".
- "20 Poèmes de Jean Richepin."
All these works so affected should be reverted to their useful main-entry points. Leave the process of creating generic access points to the categories and so on.
Would the person(s) who made these changes kindly unchange them?
