An excellent book for beginners. You can learn a little or a lot, depending on your preference. This book has been around for a while–Albert Einstein liked it, and wrote a cover blurb.
Starting in the 90s, I finally began studying the night sky in earnest, wishing to learn all the constellations I could see from New Hampshire, USA. I bought an excellent beginner’s book, H. A. Rey’s, The Stars: A New Way To See Them. Highly recommended–not only does it go through the sky in an easy-to-follow manner, but it also explains a fair amount of the underlying celestial mechanics in an easily understood, visual style. From there, I started learning the sky the way I’d always hoped to.
