The Wikipedia entry was created on Nov. 7th, 2005, and has been regularly updated until the latest update on October 11th, 2007. This information required a little bit of digging through the History tab. The Encyclopedia of Chicago article is copyrighted for 2005, but there is no specific date for when the article was created.
The Wikipedia article has two sources in its reference section. One of the references is clickable and takes you to a Government fact website. The Encyclopedia of Chicago article has three sources in its bibliography, none of them clickable. It is worth noting, however, that the amount of information in the Encyclopedia of Chicago article is much less than in the Wikipedia article. The Wikipedia article, for its relative size, should have many more sources than the Encyclopedia of Chicago.
Wikipedia has six external links, all of which are clickable and take you to a variety of pages ranging from a Chicago Reader article about Old Town to Old Town’s website, http://www.oldtownchicago.org/. Embedded within the text are links to other, related Wikipedia entries, for example, a page about St. Michael’s Church located within Old Town. The Encyclopedia of Chicago article contains no external links, but several internal links to related topics, such as the Old Town School of Folk Music.
The two articles are drastically different in the amount of information presented. The Wikipedia entry covers a wide range of topics - early history, the hippy years, photo galleries and pop culture references to Old Town. The Encyclopedia of Chicago focuses solely on history (though this seems to be an intentional theme). Even within the topic of history, however, the Wikipedia article contains more information.
In the discussion section of the Wikipedia page, several people took issue with items posted in the article. As a point of clarification, one person commented that Old Town and Old Town Triangle are two different neighborhoods with different bordering streets. Another person commented that the “trivia” section was inappropriately titled, and should be changed to “popular culture”. This user cited a Wikipedia rule to back his claim, and it appears that the appropriate changes were made. The Encyclopedia of Chicago article contains no such discussion board, at least not provided on the page of the article. This is, however, an article written by one authorized writer, not simply any person who wishes to contribute (as is the case with the Wikipedia article).
The Wikipedia page seems extremely useful, providing a breadth of information, pictures, and internal as well as external links. However, it lacks good citation and sources. Thus, any information taken from this page should be taken with a grain of salt, and if used for important situations should be checked against other sources. The Encyclopedia of Chicago article was also useful, but covered a very limit aspect of Old Town (its history only). Even for that subject, the amount of information was less than Wikipedia provided. However, this source seems more trustworthy, provided appropriate references for the amount of information given. All in all, I liked the Wikipedia article better, because the range of information was wider and the complexity of information more in depth.
