157421 Carolpercy           Discovered 2004 Oct. 8 by T. Glinos, D. Levy and W. Levy at Jarnac.
Carol Percy (b. 1964), a professor at the University of Toronto, studied James Cook's 1768-1771 Endeavour journal and how it was "corrected" for publication. She has also examined the social impact of the standardization of English, especially as it relates to those marginalized and/or educationally disadvantaged.
