JURN’s GRAFT repository search tool has updated. I cleaned out several hundred dead ‘site not found’ URLs which had crept in since last summer, and fixed a surprising amount of re-directs to new repo domain names (I thought these things were supposed to stay put). And that was on what was a thoroughly cleaned and checked URL list. I’ve also added around 100 recently-announced repositories. Even after the removals and fixes the current tally of URLs still sees GRAFT searching across around 1,300 more repositories than OpenDOAR’s 3,300 (their latest figures).
Unlike JURN, GRAFT searches across records and full-text alike. Which means… It’s Big, so it’s not much use just tapping in a few keywords and hoping for the best. It’s ideally used with relatively sophisticated search modifiers and a few seconds of pre-planning.
