Here are a few links to different Intro to Logic texts that teach Syllogistic Logic. Gensler is the cheapest and has an easy method for testing validity, called the star test, but is less traditional. The others take a more traditional approach.

Gensler

Copi

Also, you may want to try Carneades.org. He has video series on the subject:

Categorical Logic at Carneades.org

Hope this helps!

I really liked Irving Copi's Introduction to Logic. I don't know if its the best for self-learners per se but over all its just a great logic textbook and really helped me out. Also, Irving Copi studied under Bertrand Russell while at the University of Chicago so there's some bonus points right here.

Dude... Aristotle's ideas about categorical syllogisms are way out of date. You should be saying "It's the same with people who talk about logic but have never read a contemporary textbook like Copi's Introduction to Logic". If the people who talk about logic don't even know about Copi's Rules of Inference THEN we should jump on their backs. Aristotle was smashed by George Boole lol

Know this back and forth, for starters. If there is any passage of this book that gives you any pause of understanding whatsoever, then you're not even ready to start thinking about maybe eventually contributing something to logic.

Not necessarily boolean logic.

Here are the books they use for the two classes I mentioned

The first one is logic for philosophy http://www.amazon.com/gp/aw/d/0205820379/ref=mp_s_a_1_1?qid=1463700116&sr=8-1&pi=SY200_QL40&keywords=copi+logic&dpPl=1&dpID=41gXn3dBTPL&ref=plSrch


The other one is specifically for programming logic and design

http://www.amazon.com/gp/aw/d/1285776712/ref=mp_s_a_1_1?qid=1463700168&sr=8-1&pi=SY200_QL40&keywords=programming+logic+and+design&dpPl=1&dpID=51K7i7XT1cL&ref=plSrch

I took an intro logic course this past fall St my community college and we used this textbook http://www.amazon.com/Introduction-Logic-Irving-M-Copi/dp/0205820379

My prof picked and chose chapters. I really really enjoyed the class and this book. I got an A in the class if that helps endorse it from a new philosopher's POV.

I took that as a class, Not the textbook I used but looks similar on the inside.
