The Massachusetts Historical Society primarily collects manuscripts—the letters, diaries, and other personal papers of individuals and families. The Society holds many famous documents such as Paul Revere's own account of his famous ride and manuscript copies of the Declaration of Independence by both Thomas Jefferson and John Adams. However, the true strength of the collection lies in how millions of pages of documents weave together as primary sources for the study of American history.
In addition to manuscripts, the Society holds large collections of books, pamphlets, maps, newspapers, and photographs, as well as works of art and historical artifacts that support research in the library collections.
The Manuscript Collection consists of more than 3,600 separate collections of personal and family papers and, to a lesser extent, institutional and early business records that date from the beginning of European settlement to the present.
The Photograph Collection consists of approximately 120,000 images that span the development of photographic technology, including hundreds of daguerreotypes, tintypes, ambrotypes, glass-plate negatives, and carte-de-visite portraits of individuals and family groups.
Books and pamphlets printed through 1821, including a large number of 17th-century Massachusetts imprints and many early foreign publications, and broadsides and newspapers, comprise the Early Imprint Collection. The collection also includes modern reference materials, biographies, and pamphlets.
The Society holds more than 10,000 broadsides--single sheets of paper printed on one side that served as the primary tool for public announcements.
The Map Collection consists of approximately 2,500 maps and charts that illustrate the history and development of the United States.
The Society's collection of graphics consists of approximately 4,000 portrait prints and drawings, 230 silhouettes, and 2,000 images of historical events.
The Newspaper Collection contains 300 titles, ranging from single issues of American and foreign newspapers to extensive runs of early Boston papers.
