When you're looking for basic info for your research, Wikipedia can be a good place to start.
Take their article on New Year's Day, for example. It includes the history of the holiday, which day actually constitutes the "new year" in different calendars, and celebratory customs in various cultures.
In the past, use of Wikipedia has sometimes been discouraged. The reasoning goes that anyone can edit it. While this is true, there is also a robust community of users dedicated to watching out for misinformation, especially in articles on controversial topics.
All the same, it pays to use it only as a starting point for research and to be cautious about where the information came from. You can always check to make sure the article has plenty of citations at the bottom showing the authors' sources. Follow those links and see what you think of them.
The library may have more or different resources on your topic that have already been vetted for you as well. If you have any questions about how to access the library's content this quarter or if you're just not sure whether what you're finding online is legitimate or not, please don't hesitate to Ask a Librarian.
