I liked the chapter on DMCA from the 5-volume E-Commerce & Internet Law. It was super detailed.

I haven’t read volume 1, but apparently half of it is about data scraping, and I expect it to be similarly detailed. So if I were you, that’s where I’d start.

Another option is looking for “robots.txt” at Google Scholar and trying various keywords like “legality”, “scraping”, “case law”, etc.

The internet.
