Open access material appears to have fallen of the wikimedia radar a bit in the last year perhaps because a lot of it is rather hard to use. Probably the biggest issue is that a lot of papers cover a very narrow area within which wikipedia doesn’t even have a general article. Some of this is simply because wikipedia is weak in certain areas but others look suspiciously like publication padding. There are various strategies to deal with this but most of them run into the next problem.
The is a lot of junk in the databases. Sure if you stick to PLOS ONE most papers will meet a certain minimum standard. Beyond that things get interesting. Anyone can start an open access journal and while there are many decent attempts to do so there are also a lot of scammers and cranks out there. Scammers target the pay to publish model (which a lot of open access follows) by setting up a legitimate looking website and then accepting everything sent to them where the author pays the relevant fee. Cranks just want somewhere to publish their cold fusion and free energy papers that looks legitimate. Checking against Beall’s list provides a degree of protection but well, it is big, new journals pop up all the time and it doesn’t list the journal responsible for this paper arguing that the old Venera images show lifeforms on the surface of Venus.
So if want to add open access content to wikipedia how to go about it. I’m sure the are various methods but this is mine. Firstly I’ll identify journals that publish a lot of papers that can be used for sourcing wikipedia articles. Archaeology, astronomy and history are generally good choices here but there are others. I’ll search for these through DOJA Secondly I’ll see if I understand them. The European Geosciences Union publishes some great journals and the ones covering space science are a good source of things to cite but you need some serious physics to understand a lot of them. Thirdly I’ll make a judgement as to their reliability. I tend to do this by checking who they are affiliated with (if anyone) and if I trust them. I’ll also check them against Beall’s List and just by poking around the site a bit to see what they have published before. After that its just a matter of checking them every few months to see if they have published anything new of interest. Examples of journals I do this for are Internet archaeology and the Journal of Lithic Studies.
Another approach is to get personal recommendations from people active in the field. An example of this would be Polar Research.
