There are now 10 logicbites, very much intended for students. They introduce Chapters 1 to 10 of IFL, varying from one page to five, often quoting from other people’s textbooks (and sometimes criticizing them!).
I’ve found it surprisingly fun to go back, in most cases after many years, looking at how others have handled introductory topics. My book is very far from perfect, and needs a third edition (yes, really); but I can see why I was originally moved to write it, back in the day!
