I'm back at work from an extended break only to find that my favourite statistics portal OFFSTATS is no more :-( https://www.library.auckland.ac.nz/about-us/collections/decommissioned-databases
I received an email from them explaining that they no longer have the resourcing available to maintain and develop the database. Also, as much of the content can now be discovered through other approaches they felt the need for this type of search tool was not so relevant as it had been a few years ago.
A shame but understandable from their point of view. It was always a popular resource on my search workshops and often featured in the participants' "Top Ten Tips". It was one of the few resources of this type in which humans assessed and monitored the quality and relevance of the sites listed. Very sorry to see it go.
