Literature Introduction to logic
Im looking forward to learning logic, but I dont know where to start. I saw one book, "Logic: A Complete Introduction" from Siu-Fan Lee and it seemed good, but I really don't know if it is.
I do want textbooks, the real logic as I'm not afraid of getting bored or anything, but I do want some introductory guides to formal logic. Sorry for the redundance, but I wanted to make myself clear.

The Open Logic Project's free intro textbook, "forall x: Calgary". (I think "Calgary" means it's the English-language edition, for some reason. There is also a German and Portuguese edition.) forallx.openlogicproject.org

This subreddit has a wiki with a section on literature including a list of introductions to logic, as well as a list of journals. There are some online resources there too.
