In the Morgan Library's collection you'll find Literary and critical reviews as complete books or chapters in books. In LancerQuest you can either perform a KEYWORD search on your author (last name is sufficient) and the title of the work OR a Subject Search using the title of the work as the subject.
Click on the title and then Description to see the table of contents for that book. Some older books will not have the table of contents and you'll have to locate the book the shelves to review the table of contents.
Use Google Scholar to locate articles that may be freely available or to locate other sources that may have cited your source.
