Wikipedia Reference Desk
WP:RD redirects here. You may also be looking for Wikipedia:Resolving disputes, Wikipedia:Redirect, Wikipedia:Revision deletion or Wikipedia:Deletion review. Also see Wikipedia:WikiProject Resource Exchange for sharing or requesting specific source materials for Wikipedia development. The Wikipedia reference desk works like a library reference desk. Users leave questions on the reference desk and Wikipedia volunteers work to help you find the information you need. Before asking a question, please try using the search boxes to search Wikipedia as a whole or the Reference Desk archives. You can often find the answer you're looking for more quickly with a search than by waiting for a response. For information on any topic, choose a category for your question:
Computers and IT Entertainment Humanities Language Computing, information technology, electronics, software and hardware Sports, popular culture, movies, music, video games, and TV shows History, politics, literature, religion, philosophy, law, finance, economics, art, and society Spelling, grammar, word etymology, linguistics, language usage, and requesting translations Mathematics Science Miscellaneous Archives Mathematics, geometry, probability, and statistics Biology, chemistry, physics, medicine, geology, engineering and technology Not sure where your question belongs?
