I have written a manuscript that describes the biographies of 100 people over the past 200 years. You'll forgive me if I do not disclose the nature of these people. Anyway, because of the nature of each entry - average three pages - I researched many websites and ended up using material from Wikipedia. Now, my question to the forum is, is it legal for me to use Wikipedia text as long as I reference the website, etc? Many thanks in advance.
