Antelman et al. (2005) hand-tested the accuracy of the algorithm that Hajjem et al.'s (2005) software robot used to to trawl the web and automatically identify Open Access (OA) and Non-Open-Access (NOA) articles (references derived from the ISI datab

This is a second signal-detection analysis of the accuracy of a robot in detecting open access (OA) articles (by checking by hand how many of the articles the robot tagged OA were really OA, and vice versa). We found that the robot significantly over

Le mouvement du libre accès à la littérature scientifique attire chaque jour de plus en plus l'intérêt des intervenants dans le domaine de publication scientifique. Les points de vue sont divergents pour des raisons diverses: scientifiques, poli

Articles whose authors make them Open Access (OA) by self-archiving them online are cited significantly more than articles accessible only to subscribers. Some have suggested that this "OA Advantage" may not be causal but just a self-selection bias,

Many studies have now reported the positive correlation between Open Access (OA) self-archiving and citation counts ("OA Advantage," OAA). But does this OAA occur because (QB) authors are more likely to self-selectively self-archive articles that are

Eysenbach has suggested that the OA (Green) self-archiving advantage might just be an artifact of potential uncontrolled confounding factors such as article age (older articles may be both more cited and more likely to be self-archived), number of au

Incentivizing the Open Access Research Web: Publication-Archiving, Data-Archiving and Scientometrics
The research production cycle has three components: the conduct of the research itself (R), the data (D), and the peer-reviewed publication (P) of the findings. Open Access (OA) means free online access to the publications (P-OA), but OA can also be

We analyzed the effect of providing 'Open Access' (OA; free online access to research articles) on their 'citation impact' (how often they are cited). Using a subset of the ISI CD-ROM database from 1992 - 2003, we compared, within each journal and ye
