From the late 1960s, however, increasing financial problems, combined with severe flood damage, led to the conclusion that it was no longer viable for the Society to maintain its Library. Cambridge University Library acquired the Library's collection in 1993. There had been a sign of things to come when a notable chairman of the Library, Sir Alan Burns (who in 1948 had published a study called "Colour Prejudice", a groundbreaking contribution to the subject), resigned from his post in protest at the Society's attempt to sell off Library books in order to supplement its income.
