The museum is a non-profit making, permanent institution in the service of society and of its development, open to the public, and which acquires, conserves, researches, communicates and exhibits, for purposes of study, education and enjoyment, material evidence of people and their environment. Museums can be many and varied. The official definition embraces everything from a zoo to a library, but for purposes of this analysis, we concentrate on institutions that house and display collections of moveable heritage, be it scientific, cultural, or artistic.
