How much work is self-archiving? Leslie Carr and Stevan Harnad, Keystroke Economy: A Study of the Time and Effort Involved in Self-Archiving, a preprint. Abstract: 'A common objection to self-archiving is that it is an extra task that puts an unnecessary burden on each researcher. In particular, the need to enter the extra bibliographic metadata demanded by repositories for accurate searching and identification is presumed to be a particularly onerous task. This paper describes a preliminary study on two months of submissions for a mature repository and concludes that the amount of time spent entering metadata would be as little as 40 minutes per year for a highly active researcher.'
