The international conference "What's new? Revisiting new museology 30 years later" takes "The New Museology", the book edited by Peter Vergo and published in 1989 as a starting point of a discussion about functioning of the museum institution and the relationships affecting its program. 30 years after the announcement of the idea of new museology an attempt is made to revise its assumptions, ask about those that have been achieved, as well as those still requiring active efforts. The keynote lecture will be given by Nick Merriman, director of the Horniman Museum in London and professor of museum studies at the University of Manchester.
