The debate over what or if to charge admissions is part of a larger debate over what museums should do and be. The model of the past century for museums, Feldman said, is “build, grow and acquire,” which is expensive and demands that no source of revenue be overlooked. The newer conception of museums involves ideas about what should be done with the existing collections in order to improve access and increase understanding, which is why a growing number of institutions are putting their collections online and trying to make the museum experience more interactive. The largest museums in the country are attempting to pursue both models, but the result has been that their actions on the one hand work against the increased access they hope to achieve.
