Needs a new edition but comprehensive enough for GPLv2: https://www.oreilly.com/library/view/understanding-open-sour...

Not an expert but usually F/OSS licenses are mainly about:
- Patent grants (either grants patent-use or doesn't)
- Copyleft (should modifications be open sourced. ex: AGPL is the strongest FOSS copyleft, whilst SSPL builds on it to make it even more stronger)
- Copyright (owners who are licensing the code)
- Warranty and Liability
- Terms of use (ex: FOSS licenses don't enforce restrictions on commercial use like CommonsClause does)
