Oxford are ok, they are most informative and largest ones. I used Atlantic Jeppesenfor my ATPL exams, and recently i borrowed Nordian for knowledge refresh.
There is big diferance in number of pages (Air Law Oxford-670 pages Atlantic 322, Nordian 290)
Also Oxford and Alantic can be found for download, but as Phil mentioned, there is something called copyright, and you are violating it (well I also downloaded them to check them out, bought them after that
)
