I've read some of your stuff over the years and was appreciative of its accessibility. https://pages.cs.wisc.edu/~remzi/OSTEP/ https://pages.cs.wisc.edu/~remzi/OSTEP/ The above is another example I appreciate: the authors charge for physical copies and complete documents but generally make the work content available for free. I've bought a physical copy in that case because I really valued the work.
