Overview

This bot adds links to citation templates, providing alternative open access versions to references in Wikipedia articles. See also:

You can also simulate the bot on any page for additional references via its web interface: https://tools.wmflabs.org/oabot/

Update 2020: we've started the large-scale addition and maintenance of more identifier-related citation parameters, see Wikipedia:Bots/Requests for approval/OAbot 3.

Scope

The bot only edits in main space. It is compliant with the bot exclusion templates: to prevent OAbot from editing a particular page, you can use {{bots|deny=OAbot}} (for instance). There is no way to prevent OAbot from changing a particular template in a page.
The bot only edits cite templates (based on CS1/2), excluding {{cite web}}, {{cite news}}, {{cite arxiv}} and {{cite book}}.
The bot does not make changes to citations where at least one parameter is known to link to a freely available full text (such as |arxiv= or |pmc=).
After running the bot, the operator manually fixes the very rare cases of ambiguity, which show up at Category:CS1 errors: URL–wikilink conflict and used to show up at Category:Pages with citations having redundant parameters.
