On the Milton Society of America's webpage they have a page of recent or in-progress publications which I thought was interesting and quite helpful! Not only does it have the latest on Milton academia but also the latest scholars working on it. I found a couple articles that have been recently published as well as some that are still forthcoming. I jotted down the names of the authors to look them up and maybe try talking to them! If you're stuck and/or looking for people and information I would suggest taking a glance.
