Yes, I feel it is perfect for multiple and even thousands of sources. The cross-referencing feature allows for links to other articles and sources.
From the main page:
www.wikipedia.org one can search for a specific article, say "Golf Course Architecture" and get an article with cross-references ties to say, "CB MacDonald" or "Huntingdon Valley Country Club" if they are contained in the main article and have articles or "stubs" of their own.
A stub could be something like: "Huntingdon Valley Country Club is a club located in Abington, PA with three nine-hole golf courses designed by William Flynn. Each nine is labelled alphabetically and was designed to be progressively harder, with the B-C combination being the most difficult. The C-Nine was restored in 1999 after being abandoned for over 50 years."
In that stub, William Flynn can then by hyperlinked to a seperate article on Flynn, which could contain hyperlinks to similar stubs as the one with Huntingdon Valley for all his other courses, in addition to biographical information.
With a donation, I believe it is possible to take somewhat proprietary owneship over a set of articles, therefore, an administrator can be established to control the flow of data and access.
