Musings about librarianship: Library Discovery and the Open Access challenge - Take 2

"At the limit when nearly everything is freely available it is possible to consider whether library will have a place in the discovery business. After all, if all researchers have access to the same bulk of journal articles, does it really make sense for each institutional library to provide a separate discovery solution? Even today, many researchers prefer using Google Scholar and other non-institutional discovery solutions that operate at web scale and some (mostly students) grudgingly use our discovery systems to restrict discovery to things they have immediate access to.

This of course is the library discovery will be dead scenario when (almost) everything is free  and not everyone agrees. Some argue, that libraries can add value by providing superior and customized personalized discovery experiences because we know our users better (e.g what courses they taking/teaching, their demographics etc). Then there are plans to leverage linked data etc but I know regretfully little of that. But the day when open access is dominant is still not here. We live in the world where there is a mix of toll based access and rising but uneven free access, Scihub notwithstanding. I opined that for now "if we really want to stay in the discovery business we need to be able to efficiently and effectively cover the increasing pool of open access resources". So how does you ensure the library discovery system includes as much discovery of free open access articles as possible?"
