I just noticed this piece written by Jeff Perkel in January who, after "poking around" the iSpecies blog, wrote Why Google is good for science. Well, yes and no. On the one hand it's fabulous, but on the other hand they can play rough. For example, iSpecies used Google Scholar to find scientific papers for a species name. The traffic was pretty minimal in the scheme of things, but Google have now blocked iSpecies (and as a consequence my whole University - gulp!) from accessing Google Scholar.
Before anybody says, "but you got what you deserved because you broke Google's Terms of Service",
After venting my spleen, the reason -- as I should of guessed -- is "intellectual property". Google Scholar's agreements with the publishers that they index prevents Google from making it available other then through the web site. Thanks to Rebecca Shapley for clarifying this. Once again, scientists are being ill served by our publishers. Perhaps somebody needs to set up an Open Source/Open Access equivalent of Google Scholar.
This is what I originally wrote, which perhaps is another reason publishers don't want Google Scholar having an API:
There would also be a potential market. In the UK we rate our research based on a number of factors including journal impact factor, as part of the gargantuan Research Assessment Exercise. Impact factors are supplied by ISI, and Google Scholar results compare well with that source. Just think of the possibilities of a service that used Google Scholar to rate scientists' output. It could even be part of a service like LinkedIn, whioch I stumbled on via Pierre's blog on geotagging RSS feeds (which is a whole separate issue).
About LinkedIn, it seems that Nature/Connotea is about to create a social (scientific) network called "Nature Network Boston". see http://blogs.nature.com/wp/nascent/2006/04/web_20_in_science.html...
ispecies is still running and getting results. Are you displaying papers from Google Scholar from cashed results ? (the results look the same so I guess not :). Is there a reason why you don't get the papers from Pubmed ? Does Pubmed have the same limitations ?
