The Salem package is based on the The Salem Withcraft Website created by Richard Latner. The package includes all of the data sets from the website as R data frames. The data have been reorganized from the original structure for ease of use in R. (Copies of the original tab delimited raw data sets are available both at the Salem Witchcraft site and in the github respository for this package.)
A detailed discussion of the data sources can be found on the the notes page of the website. .
A list of scholarly sources about the Salem witch trials (through about 2008) is on the bibliography page.
An updated list of reference website links from the bibliography page is given here.
