Papers contain copies of biographical information on Jaroslaw de Zielinski, copies of lesson pricing lists and handbills of concerts he conducted while living in Grand Rapids, Michigan. Also contained in these papers are two sets of translated letters dating from 1871 to 1890 between Zielinski and one of his long-term pupils Edith V. Rann. The first is an original translated copy produced by Edward Symans and contains handwritten notes in pen. The second copy has been reproduced from this original set with slight variations to years 1874 and 1890. The letters contain Zielinski's philosophy in teaching music as well as personal matters. Other items include a copy of a holograph produced by Zielinski, a copy of a bookplate cover by artist Ruth Thomson Saunders, copies of post card addresses and three photographs that are undated and unnamed.
