I'd appreciate if anyone could help me figure out what font Munkres used in his famous "Topology" book. I am interested in the font used in the main body as well as the font used in his "theorem" environment.
I searched the Internet for similar questions with no success. I also tried "myfonts.com," but that did not yield any satisfactory results. Finally, I looked at PDF version of his book and by going to "documents properties," I checked the fonts that the pdf viewer was able to detect. However, the results (mainly variations of Courier, Helvetica, and Times) do not look quite similar to what it really is.
The reason I am asking this question is that Munkres strikes me as an incredibly easy book to read and I would like to format my papers in a similar manner. As a example, his "f" in a theorem environment looks differently than his "f" in a math mode, which makes it extremely easy to distinguish between the two.
Below you can a few screenshots from his book.
Thank you for all your help.
EDIT: I understand that some of you may think it is a duplicate of How do I find out what fonts are used in a document/picture?, but I tried methods mentioned in that post and it did not solve my problem. However, thankfully some of you have already answered my question, which I am very grateful for.
