Lists would fall under category 2, e.g.


The (I think) relevant bit here is that any list owner could bookmark any
article from anywhere (regardless if it's something the institution
subscribes to) and TARL would create an openurl based on the metadata
available from the bookmarking process (which, in *some* cases could be
spotty).  And, as you note, may be freely available and not managed in your

Theoretically, RefWorks, Mendeley, Zotero, etc. could be other possible
examples of your category 2, but they'd be harder find public examples for.

Outside of these (and maybe even outside of Google Scholar alone) I think

individual source.
