As stated in the title, I am interested in learning about Modal logic as a layman in the subject. I would appreciate any books, videos, articles, ect. Thanks!
The book I'd recommend for the novice (especially, on a philosophy Q&A platform) is Modal Logic for Philosophers by James W. Garson.
It achieves its promises (see the book's website) - fairly accessible to the student, focused on philosophical concerns rather than mathematical technicalities and diagrammatic material to facilitate visual understanding.
It should be fairly accessible, but it gets into technical detail right away. It also assumes that you're comfortable with the object-language/metalanguage distinction and defining the truth conditions of a well-formed formula inductively. It is somewhat mathy.
The link below is to a set of lecture videos on modal logic titled "Introduction to Modal Logic", and they look pretty good.
Also, there are some nice short videos on YouTube by Carnadeas.org. Here's a link to the playlist.
As for a book, I personally liked "Modal Logic An Introduction" by Brian F. Chellas.
For a really first start , you may have a look at Logics by Nolt. Modal logic is only a chapter of this book and the basics are well explained.
Nolt also has written Schaum's Outline Of Logic ( and the book, has a new edition by Varzi); I think it contains an additonal chapter on modal logic.
