WikiProjects Newspapers and Magazines spun from WikiProject Journalism and like WikiProject Academic Journals, these projects focus primarily on the textual periodicals themselves rather than the humans or organizational structures behind them.
News is what someone, somewhere, doesn't want reported: all the rest is advertisement.[1]
Behind the scenes in the wiki-lawyer trenches, hundreds of Wikipedia editors debate discuss at the Reliable sources/Noticeboard to which degree different sources are suitable for usage within Wikipedia articles. Is it news...or advertisements?
Wouldn't it be great if there existed a digital resource that readily made available the sum of human knowledge about various topics, something like an encyclopedia that included different newspapers in order to help editors and readers alike ascertain the reliability of said sources?
Reading Skimming sources takes time, so Wikipedia users sometimes try to gloss over by checking whether there is a blue link, which could be an indicator that the article topic is notable. It may WP:SHOCK some, but it does not necessarily mean The Onion aka America's Finest News Source is reliable.
Conversely, a red link does not mean popular newspapers like Die neue FuĂballwoche are unsuitable for usage within English Wikipedia for an article's source.
Tracking source usage within Wikipedia is already done for magazines and journals. You can find an example at WP:Magazines cited by Wikipedia and read last year's Signpost coverage about it.
In addition to the venerable Signpost, there are 11,743 articles inside WikiProject Newspapers and 12,007 articles inside WikiProject Magazines. These two projects are distant cousins of the more broad (pun intended) WikiProject Journalism.
