This is newsworthy?

EDIT: This is a serious question... The article is a pointer to iBook versions of free PDFs. I can't imagine why this has been so well received. You can even view the original PDFs in iBooks... What am I missing?

They are missing a few chapters compared to the online versions (easy to see which ones; just look at what chapter numbers were skipped in the contents). Still much easier to read than PDFs.
