%A Stevan Harnad %J High Energy Physics Libraries Webzine %T How and Why To Free All Refereed Research From Access- and Impact-Barriers Online, Now %X Researchers publish their findings in order to make an impact on research, not in order to sell their words. Access-tolls are barriers to research impact. Authors can now free their refereed research papers from all access tolls immediately by self-archiving them on-line in their own institution's Eprint Archives. Free eprints.org software creates Archives compliant with the Open Archives Initiative metadata-tagging Protocol OAI 1.0. These distributed institutional Archives are interoperable and can hence be harvested into global "virtual" archives, citation-linked and freely navigable by all. Self-archiving should enhance research productivity and impact as well as providing powerful new ways of monitoring and measuring it. %D 2001 %K refereed journals, electronic publishing, Open Archives Initiative %L cogprints1640 %V 4
