Many of the most fascinating books in the Heritage Collection are part of a series. A good number of the best authors of juvenile history, such as H. E. Marshall, Alfred J. Church, Jacob Abbott, and others were prolific writers and produced not just one but an entire collection of first rate books. Most of their books, therefore, are recommended as part of a series rather than as stand-alone books.
Overall at least two thirds of the books in the Heritage Collection are part of a series. Some are written by a single author, but others are written by a group of authors under the direction of a publisher. Some collections are confined to a relatively narrow theme, such as American Frontier History, or Exploration, while others are broad and wide-ranging. Our complete list of series can be found here, and several of our favorite series, selected from all three reading levels, are listed below.
