Materials in the Heritage Tourism Collectibles series are organized by material type and further arranged alphabetically. There are four subseries; Booklets, Calendars, Ephemera, and Postcards. Booklets and calendars are listed by the title of the publication. Booklets include a wide range of topics including building materials, decoration and historic homes. Postcards were originally housed in both file folders and in albums and arranged by location which is the reason for duplicate location listings.
