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 box to find the answer you're looking for. You may also try searching the reference desk archives. For information on any topic, choose a category for your question: | | | | | | | Computers and IT | Science | Mathematics | Humanities | | Computing, information technology, electronics, software and hardware | Biology, chemistry, physics, medicine, geology, engineering and technology | Mathematics, geometry, probability, and statistics | History, politics, literature, religion, philosophy, law, finance, economics, art, and society | | | | | | | Language | Entertainment | Miscellaneous | Archives | | Spelling, grammar, word etymology, linguistics, language usage, and requesting translations | Sports, popular culture, movies, music, video games, and TV shows | Subjects that don't fit in any of the other categories | Old questions are archived daily |
