Do you flip to the back of a book before you buy it? Indexes and bibliographies, more than a table of contents, provide a better glimpse into the ideas of a book. I appreciate them when they’re at my fingertips but assembling them is a tedious task that requires absolute attention to every page. But one of the benefits, as Ken Turino and I discovered while indexing Reimagining Historic House Museums, are the common ideas that cut across the chapters contributed by two dozen leaders in the field.

Mission statements have long been used in nonprofit organizations and the version of “collect, preserve, and interpret [insert your museum’s topic here]” has now become a cliché.

In our book, President Lincoln’s Cottage, the Harriet Beecher Stowe Center, and the Trustees demonstrate how meaningful mission statements permeate decision-making at every level of the organization. Indeed, as my thinking continues to evolve on mission statements, they should not simply describe the work of the organization but address a major problem or issue in the community—that’s what makes them meaningful to a broader segment of the public.
