The paper coincides with the 90-th anniversary of Lev Zakharovich Amlinsky, professor and doctor of science in pedagogy. The findings of Lev Amlinsky’s studies represented in his recent publications in «Scientific and Technical Libraries» journal for the period of 2011–2016 are analyzed. The subject scope of the works comprises: design of remote library and information services and library resources, architectural and constructional design, provision of psychological comfort for patrons and librarians. Lev Amlinsky’s concept of library design is an anthropocentric one, i. e. the interests of humans, patrons and librarians, must primarily come to the fore when designing libraries. The necessity for apprehending traditional libraries as the space for patrons and librarians, rather than the physical space for books is substantiated. Technological dependence of interior library space has to be replaced with psychological and ergonomic expediency. The scholar has validated a fundamentally new concept of library space arrangement: the libraries are pieces of architecture, however, their interior architecture should meet their functional purpose. The role of efficient architect – librarian cooperation between an under librarian’s leadership is emphasized.
