In April 2016 Manchester eScholar was replaced by the University of Manchester’s
new Research Information Management System, Pure. In the autumn the University’s research
outputs will be available to search and browse via a new Research Portal. Until then
the University’s full publication record can be accessed via a
temporary portal and the old eScholar content is available to search and browse via this archive.
