I’ve linked to a few blogs below about some controversy surrounding the authorship of posts in Wikipedia. Content and politics aside, I think after reading both articles, you’ll agree that central issue of concern here is attribution: whose words are these? Anonymity on the web can be both good and bad, but for academic research its mostly bad.
Whose words are these? This is a question you will not need to ask yourself if you use the library databases. Each article you access from the library will include complete bibliographic information: author, title, source, volume and issue, date of publication, etc. This information is important in helping you determine the currency and authority of the information, and whether or not you should be using it to make conclusions or recommendations. Furthermore, knowing who the author is can also be very helpful if the topic you are searching is not widely covered in the academic literature. If all else fails, you can often contact the author directly and ask for recommended readings or updates regarding his/her research.
