In November 1918, Archer was appointed to the Seed Improvement Committee of the Advisory Council of Science and Industry (
Commonwealth Institute of Science and Industry from 1920) as secretary and investigator. It is thought she wrote their bulletins (1922–23) on improving crops and classifying barleys, oats, and wheat. With little librarianship training, but with great administrative skills, she turned scattered collections into a smooth running system of libraries. As Citrus Preservation Committee secretary she compiled an agricultural research register; was effectively head librarian of divisional and experimental stations' libraries. This included the universal decimal classification which she later introduced at the
CSIRO. She created a union catalogue – a great unifying force for CSIRO Libraries, basis of the National Union Catalogue of Monographs (1960).
Contribution to the library sector Archer made a lasting contribution to the library profession as foundation member of the
Australian Institute of Librarians (1937) and first female president (1948–49). Despite not having any formal library education, in 1941 Archer established the examination branch of the Institute. The Institute was reconstituted the
Library Association of Australia (now the Australian Library and Information Association) with Archer an active past president (1950–53). Archer had a particular interest in special libraries, signing a petition in 1951 for the establishment of a Special Libraries Section, which was formed in the same year. == Death and memorialisation ==
