The downtown building grown: the 1998 expansion and the Heritage Center

1914–2021 · the post office absorbed, the city's memory given a room

The neighbor building: The 1969 library stood on the same downtown block as a building with its own civic course. The United States Post Office for Mishawaka built its freestanding building at 120 South Church Street in 1914 — the building from whose steps the town's recruits of May 1917 marched to the depot, in the photograph the Heritage Room still displays — served there until its move about 1970 (the library's timeline says 1970; Peter De Kever's spoken account says 1969, and both stand), and from 1974 held the Mishawaka Police Department, which moved from City Hall into the emptied post office and stayed until its own new station opened at Church and First in 1995. The library, by then, "was looking to expand," in De Kever's summary, and the expansion took the neighbor in.

1998: "Mishawaka-Penn Public Library opened its expanded and renovated downtown building, including the space occupied by the former U.S. Post Office and Police Station. This space was called the Heritage Center. The room, open limited hours, stored genealogy records, digital archives, yearbooks, microfilm and historical newspapers." The library's own timeline, published on its Heritage Room page, is the source — and the room it describes is the institutional fact at the center of this article: from 1998 the city's local-history memory had a dedicated room inside its public library, behind the post office's original exterior doors, under a portion of the postal catwalk from which supervisors once watched the mail being sorted. The Mishawaka Historical Museum's president and the city's Historian Laureate, Peter J. De Kever — the commissioned historian whose Mishawaka: A History runs under this whole build — helped assemble it: "Brought together all the library's resources — microfilm, books, files on Mishawaka history, genealogy..."

2020–2021: "The doors closed to the Heritage Center in March 2020 and during much of the pandemic, the space was renovated. Materials moved to the Adult Services Local & Family History area in the building's lower level to allow patrons more access to these items." In 2021 "the room reopened with a new name and purpose. The Heritage Room became the designated Quiet Zone at the Mishawaka Library, containing newspapers and magazines as well as displays dedicated to industries and families that helped shape the Princess City." The displays are built around five hand-crafted cases, one for each of the "Five Industries That Made Mishawaka" — Ball Band, Dodge, Wheelabrator, Bendix, and Kamm & Schellinger — with many artifacts on loan from De Kever, and further exhibits spotlighting the Jernegan and Powell families. The room and the library's Shiojiri Room together place the system among the more than 150 libraries in the Indiana Library Passport program, cited there for the rooms' historical significance. The collections the Heritage Center gathered did not leave the building: they stand one floor down, in the Local & Family History area, where the collections article below finds them.
