The annual reports of NYPL’s Branch Librarians are
filled with descriptions of the latest ethnic change in their communities, and
those observations were used to develop services and book collections for the
new residents.
Casindania Eaton used an earthquake-related metaphor to
describe the librarians’ close scrutiny of new ethnic groups arriving in their neighborhoods,
either through immigration or internal migration. In her 1948 annual report for the Muhlenberg
Branch in the Chelsea neighborhood of Manhattan, she wrote: “Chelsea does not
change rapidly, but the Library, like a seismograph, is extremely sensitive,
recording and responding to various undulations.”
Eaton earned her BA in Library Science from Simmons
College in 1929 and held three library positions in Massachusetts and
Pennsylvania before joining NYPL in 1941.
Soon after her hiring, Eaton became an active officer
of Local 111 of the United Public Workers Union, CIO. Between 1943-1949 she served as chairman of
the Union’s negotiating committee (bargaining on behalf of the maintenance
workers and not librarians), President of the Professional and Clerical
Council, Vice President of the Union, Chairman of the Organizing Committee, and
Financial Secretary.
During this same time period, Eaton was promoted to be
the Branch Librarian at the Muhlenberg Branch, one of NYPL’s busiest
branches. When Muhlenberg was closed for
renovation in 1955, Eaton was transferred to head the Parkchester Branch. In 1958 she was promoted to Coordinator of
all Manhattan branches, a position she held until her retirement in 1972.
