Josef Muller-Brockmann's books are a decent primer on the basics of graphic design (including typography). They are old but the information in them is not necessarily out of date, and the writing style is very helpful since he includes examples and explanations of how to apply the concepts practically.

If you are going to read them I would recommend "Grid Systems in Graphic Design" and "The Graphic Artist and His Design Problems". "History of the Poster" is worth getting too. Make sure to get them as books, not PDFs. His lessons about margins and font size make a lot more sense when you are viewing them in the book laid out according to his own principles.

/edit The Vignelli Canon is a nice read too. See: http://www.vignelli.com/canon.pdf

I learned a lot from "The Elements of Typographic Style" by Robert Bringhurst. I sometimes find it a bit hard to read casually, but there's a lot in there I enjoy absorbing.

My friend teaches typography at an fine arts and design school and "Elements" is the textbook. When I went to art school in the 90s it was also one of my textbooks (though it was still a relatively new book at the time). It's one of the few books that's remained on my shelf for the 20ish years since I bought it. I still reference it regularly.

I find it a nice-looking book too, which is unsurprisingly expected for its nature.

I enjoyed this one: https://practicaltypography.com/

Great link. Just finished reading through it and I feel more educated on typography. At the very least I now have a better feel of the lingo and vocabulary which surrounds typography. Thanks.

I highly recommend this one. It is divided in short sections devoted to one specific topic, directly to the point, including practical examples and indicating how to do it in popular software like Word, CSS, etc.

I would highly recommend James Felici's The Complete Manual of Typography. Goes through all the core concepts of typography and why they matter, and provides a number of guidelines.
