Holman Library carries both print and ebooks.
NOTE: some of the book returns on this list are reference book (academic encyclopedia) articles. They will provide an overview of your topic, rather than an in-depth discussion.
Try these subject terms too (change Any Field (on the left) to Subject at Advanced Search or use Subject Terms in the left menu of a basic search):
Topic: men or masculinity and clothing in the 1960s
My search returned more than 500 titles. Not all of them will be relevant or useful. Of the first three items listed, the first two look relevant. The third is looking at Ghana and it is an article.
I thought the first title, Peacock Revolution, sounded relevant to my topic, so I clicked on the title to learn more about the book. The image below shows REALLY useful SUBJECT TERMS I can click on for more information on the subject and it shows the book's description, which indicates to me that it will help me with my research.
If the book had been in print, the record would have a number indicating its location on the shelves.
This book is an ebook - and I find the link to the book on this page as well.
