Collecting is a central activity to museums. Object-based learning is the underlying principle that museums use to tell their stories to the public through different media such as exhibits, programs, classes, books, and activities. Collecting in museums is usually directed by curators who conduct research, create new knowledge, and present their work through publications, exhibits, and programs.

In recent decades, this tension has become more complicated as a result of other trends relating to changing demographics, new laws, and evolving ethics. In the future, these trends may change how museums build collections
