Abstract: Eight-hundred forty articles from core ecology journals were searched in Google Scholar (GS) to determine level and completeness of indexing and access. Testing occurred both on campus and off, and within each venue searching was divided evenly into basic and advanced modes. Off campus, about nine percent and on campus, about thirty-eight percent of links led to text that could be opened directly, without barriers. Fifty-seven percent of test articles had full citations or better, and over seventy-seven percent had at least some type of completable citation. Older articles were less likely to be represented. Full-text articles were concentrated at author sites and at a small number of provider sites. The advanced search found somewhat more full text than did the basic search. Highly cited articles were more likely to be included in Google Scholar.

The open access movement:
Putting peer-reviewed scientific and scholarly literature
on the internet. Making it available free of charge and
free of most copyright and licensing restrictions.
Removing the barriers to serious research.
