I have always struggled with this. If I buy a book I don’t want an online/URL reference in it. Put the book/author/isbn/page etc. Or refer to the magazine/newspaper/journal/issue/page/author/etc.

I mean preferably do both, right? The URL is better for however long it works.

		We are long, long past any notion that URLs are permanent references to anything. Better to cite with title, author, and publisher so that maybe a web search will turn it up later. The original URL will almost certainly be broken after a few years.
