Dear colleagues,

if a wiki contains information originally published elsewhere, the question arises how the updated wiki version of such information should be properly cited.

The Species ID wiki ( http://www.species-id.net/ ) has recently, in collaboration with the journals ZooKeys and PhytoKeys as well as the Plazi repository, imported a number of taxonomic treatments as wiki pages, and the above-mentioned issue was addressed by incorporating the generic link to the wiki page into new journal publications, and providing a suggested citation format on-wiki that includes the original work along with a permalink to the most recent wiki version and the wiki contributors until that version.

For some example pages, see http://species-id.net/wiki/Neobidessodes_darwiniensis or http://species-id.net/wiki/Sinocallipus_catba .

The publisher's news release on the matter is at http://www.pensoft.net/news.php?n=53 , and I have commented in my blog at http://www.science3point0.com/evomri/2011/04/16/citing-versioned-papers-robo... , touching upon the need for a tailored karma system.

Comments and suggestions very welcome.

With my best wishes,

Daniel
