Harpweek needed
Would be good to grab citations from Harpweek, which is a great site. I think this requires paid access, but is widely used and very useful to US historians because of the importance of the magazine in the late nineteenth century and the quality of the database. http://app.harpweek.com/SearchSpec.asp
