It’s always been annoying that academic repositories jumble together paywall / no-access / open access material, and don’t allow users to search only for open access + full-text materials. With a very few honourable exceptions, it’s a ridiculous situation — and the so-called library professionals involved in the development of such ‘standards’ should be hanging their heads in shame.

“Really, I’m deeply disappointed that this kind of thing — good metadata that will allow software to know if an item really is OA, and to get a link directly to the content as well as the landing page — doesn’t seem to be a concern of the repository communities. This has been a problem for YEARS, and if any of the various organizations involved in this stuff are even making any efforts to address it, I haven’t heard about it.”
