While editors benefit directly from TWL's publisher relationships, readers face the same obstacle of closed access paywalls that TWL was created to overcome for editors. OABot
(https://en.wikipedia.org/wiki/Wikipedia:OABOT) is a tool that finds open access versions of references in Wikipedia articles. If no URL is included in the citation, it adds one that points to an open access repository version of the source; if one is available, OABot uses the Dissem.in service (http://dissem.in/) to find these versions from sources like CrossRef, BASE, DOAI, and SHERPA/RoMEO. On an article like Cancer, which has 200 citations, 15% will have free-to-read links to repository versions added. Those links will be accompanied by a green open lock icon broadcasting their availability to readers. This expands on previous efforts led by Daniel Mietchen and other open access advocates to present icon-based indications of open access sources as part of the OA Signalling Initiative (https://en.wikipedia.org/wiki/Wikipedia:WikiProject_Open_Access/Signalling_OA-ness). The growing prominence of both open access publishing and article-level metrics (altmetrics) amplify each other on Wikipedia:
- "The odds that an open access journal is referenced on the English Wikipedia are 47% higher compared to closed access journals. Moreover, in most of the world's Wikipedias, a journal's high status (impact factor) and accessibility (open access policy) both greatly increase the probability of referencing. Among the implications of this study is that the chief effect of open access policies may be to significantly amplify the diffusion of science, through an intermediary like Wikipedia, to a broad public audience."13
Part of supporting readers is making the creation of accurate and thorough citations easy in the first place. Through a TWL partnership with OCLC, editors can now use the WorldCat API to automatically generate book citations in Wikipedia articles. They need only enter the ISBN in a citation tool, which then draws from WorldCat to return fully formatted bibliographic metadata,
