Wikipedia is an immensely popular online encyclopedia that is free and multilingual. It has revolutionized the way people research and find information. Wikipedia Day is a celebration of the 20th anniversary of Wikipedia’s creation. Wikipedia has been used in everyday life for more than two decades. Wikipedia is not considered a reliable source for educators and formal research because it can be edited, deleted, or updated by anyone. Although it can be biased and difficult to read, it is not considered reliable and can be re-used by educators and researchers for formal research. Although it may require facts to be double-checked with more reliable sources, the concept of Wikipedia Day is a great way to celebrate the freedom to access information generated through grassroots efforts. You can invite your friends to a small gathering to discuss Wikipedia’s benefits and how they have impacted our lives over the past 20 years. Wikipedia Day is a great opportunity to do some online research on interesting topics. You can see what Wikipedia has to offer and then go deeper into other sources to verify the accuracy and reliability of the information. There have been a number of films made about the topic and theme. Maybe Wikipedia Day is the right time to see one or more of these films in celebration of the day.
