no citation provided

I had a class on doing research and how to properly cite sources in my first bachelor's program, for social science and business etc. So when I had to take the same class again for my degree in law I thought I would learn how to do research related to court cases etc, but that the citation norms would be pretty much the same.
Instead, they're completely different. For example, unlike social scientists, jurists (in Austria, idk how international the standards are) don't care about who published a book or where, and they don't usually use first names, only initials.

Also, "Festschrift" (apparently also the English term) are very popular. If jurists really like and admire someone, they get together and write articles that will then be published as a book for their anniversary/birthday etc. On the one hand, annoying, because articles in those are harder to find online than those published in journals; on the other hand, very understandable for people with an ego because you definitely remember someone's name if you keep having to cite the book named after them.

...I'm procrastinating on writing my paper for the research and citation class *sigh*
