Recently, the Harvard University Library Open Collections Program released Contagion: Historical Views of Diseases and Epidemics, a digital collection you might be interested to use in your research or teaching. This collection makes available online more than 500,000 pages of books, serials, manuscripts, pamphlets, and other materials that offer historical perspectives on diseases and epidemics.
A handful of disease epidemics are highlighted on resource pages that combine historical information, links to digitized resources, and bibliographies. To start with, see the page on the 1793 Yellow Fever Epidemic in Philadelphia. To dig deeper, you can browse the collection by genre, such as broadsides or images. You may also search the catalog, fulltext, and website of the collection to find sources and guides on your topic. Or, browse the contagion timeline to see the significant dates in specific disease epidemics that are highlighted in the collection.
