Many state and local historical societies have now transferred the electronic backfile of their signature journals to JSTOR (linked below). Some, such as the journal of the Rhode Island Historical Society, are accessed elsewhere online. Others rely on home-grown database systems for backfile management. If you cannot find the journal you are seeking in JSTOR or in Josiah, check the official website of the relevant historical society for information on where electronic copy, if any exists, might be found.
All of the below databases may be searched together in whatever combinations you wish by opening any one of them and clicking on Choose Databases.
