Access to reference databases
Article quality could improve if Wikipedians were given access to reference databases such as what Credo Reference is doing.
Well, that seems like a good idea really. The tagline of Credo says "Credo Reference puts the world's best citable information at your fingertips." If it lived up to that potential, then maybe Wikipedias would improve greatly. I already have access to one database. It is a very good source to find information.
