Yes, Google Scholar coverage of institutional repositories can and will improve. But it won't make much difference as long as most institutional repositories are un-mandated, and hence near empty. To repeat, the problem is that Green OA self-archiving needs to be mandated -- by institutions and funders -- worldwide. Till it is, we are mostly spinning wheels. And if and when OA is closer to 90% than to 10%, not only will Google Scholar developers dramatically upgrade Google Scholar's power, but many other OA-specific search engines will do so too. Till then, however, it's hardly worth their while. Stevan Harnad PS: A side-bet (that I've made before): Once OA full-text is reliably near 100%, intelligent text-mining software-based tagging will outperform any prefabricated, author-generated, librarian-generated or crowd-source based tagging scheme for search and discovery. (But there's no motivation at all to develop such future wonders on the impoverished corpus we have now...) > *From:* goal-boun...@eprints.org [mailto:goal-boun...@eprints.org] *On > Behalf Of *Stevan Harnad > *Sent:* donderdag 3 januari 2013 2:09 > *To:* Global Open Access List (Successor of AmSci) > *Cc:* SPARC Open Access Forum; scholc...@ala.org T.F.; LibLicense-L > Discussion Forum > *Subject:* [GOAL] Re: New Year's challenge for repository developers and > managers: awesome cross-search**** > > ** ** > > CHEER-LEADING, CHALLENGES AND REALITY**** > > ** ** > > What is missing and needed is not "awesome repositories cross-search > tools." **** > > ** ** > > What is missing and needed is OA repository deposits, and OA deposit > mandates. **** > > ** ** > > The repositories are mostly empty. **** > > ** ** > > And Google Scholar finds what OA content there is -- wherever it is on the > web -- incomparably better than "awesome repositories cross-search tools." > **** > > ** ** > > Here is just a sample vanity search on a relatively uncommon name (try > your own):**** > > ** ** > > *Awesome repositories cross-search tool:* Harnad 140 > hits<http://network.bepress.com/explore/?q=Harnad> > **** > > *Google Scholar:* Harnad 15,900 > hits<http://scholar.google.ca/scholar?q=Harnad&btnG=&hl=en&as_sdt=0%2C5> > (author:Harnad: > 1,010<http://scholar.google.ca/scholar?q=author%3AHarnad&btnG=&hl=en&as_sdt=0%2C5> > hits)**** > > ** ** > > ** ** > > ** ** > > _______________________________________________ > GOAL mailing list > GOAL@eprints.org > http://mailman.ecs.soton.ac.uk/mailman/listinfo/goal > >
