The Gilded Age Historiography

Oct 2018
I'm planning to write a 4000 word research paper on The Gilded Age and was looking for published articles/books or basically respectable historical works on this period. Would anyone be able to provide some to help me get started?
The internet is not helping me as usual so any advice would really help me! Also, if you think this is a largely overlooked period in history and that I will not be able to fnd enough historiography or sources to help support my argument, please let me know!

Thanks a ton in advance! :)
