The best scholarly resource for information regarding the compositions of Charles Ives is the "Descriptive Catalogue of The Music of Charles Ives" by James B. Sinclair. It can be downloaded here: https://elischolar.library.yale.edu/ivescatalogue/ Note that the dating of Ives's compositions is a matter of conjecture and controversy, and the date entries in the catalog will seldom translate neatly into something you can use in MusicBrainz. As Charles himself might have said, "give it the old college try."
