A memory institution is an organization maintaining a repository of public knowledge, a generic term used about institutions such as libraries, archives, heritage (monuments & sites) institutions, aquaria and arboreta, and zoological and botanical gardens, as well as providers of digital libraries and data aggregation services which serve as memories for given societies or mankind.
