No glimmer of GLIMIR yet
Earlier this year some people (starting with Stuart Weibel, and then for example Scribe and Kathryn Greenhill) were talking about GLIMIR, OCLC’s proposed Global Library Manifestation Identifier. It would, as you’ve already figured out, be a way of identifying manifestations. Usually people think of ISBNs as doing this, but publishers can do funny things and mistakes happen, and ISBNs have only been around for about forty years. A universally agreed-upon (well, even terrestrially would do) way of identifying manifestations would be useful. Of course, so would a way of unambiguously identifying works and expressions!
Anyhoo, I asked at the time if there was anything public about GLIMIR, and was told no. I haven’t heard anything more since then, and didn’t find any news after a bit of looking around. It was on my mind as something to follow up on, though, so this is a just a post about negative results.
