In 1933, the Maryland War Records Commission published in two volumes, Maryland in the World War, 1917-1919: Military and Naval Service Records. It is from this work that the service records of 1,460 Marylanders of Polish Heritage in World War I are abstracted. The compiler has added to this information photographs of those veterans who have a military grave marker and are buried in one of Baltimore's Polish Catholic Cemerteries - St. Stanislaus Kostka, Holy Rosary, Sacred Heart of Mary, and Holy Cross Polish National Catholic Cemetery. In a few instances the graves contained a photograph of the veteran in his uniform or indication of World War I service for men overlooked in the original two volume work.

The service record usually provides the following information: name, address, place of birth, age or date of birth and military service. The records were abbreviated according to military practice and at the end of each volume a key to abbreviations in provided. The records are arranged alphabetically by surname then given. In instances where a service record was not found only the photograph of the grave marker appears (which often contains much of the same information).
