The Big Read evaluation included a series of 35 case studies designed to gather more in-depth information on the program's implementation and impact. The case studies gave readers a valuable first-hand look at The Big Read in context. Both formal and informal interviews, focus groups, attendance at a wide range of events--all showed how participating communities and partners host a Big Read, and what impact it has on partnering institutions, the broader community, and reading habits. A rich complement to the quantitative data, these cases allowed individuals to explore or confirm trends emerging in the general data collection, document memorable events or outcomes that define the unique, local character of Big Read implementations, and amplify elements of The Big Read that merited note or replication. Appendices include: (1) Administrator Protocol; (2) Librarian Protocol; (3) Teacher Protocol; and (4) Student Protocol. (Contains 41 footnotes.)
