Adding information to DOIs on journal web pages. Screenshots from the BMC Bioinformatics web page (full URL: [49]) for Spjuth et al. [29] (a) without any userscript enabled, and (b) showing the effect of the two userscripts "Add quotes from Chemical blogspace and Postgenomic to DOIs" and "Add to Connotea". The latter added a Connotea logo (a 'c' surrounded by linking arrows), which links to the Connotea dialog box for adding this paper to your library, and a number indicating how many people have already bookmarked this paper, which links to the existing entry for this paper on Connotea. The "Add quotes" userscript added the Cb logo, which links to the Chemical blogspace page for this paper, and a Pg logo, linking to the Postgenomic page. The popup titled "Powered by Postgenomic.com" (only partially shown) appears when the mouse is placed on the Pg logo, and contains quotes from and links to the citing blog articles.
