Internet search engines and libraries are both ways to find information.
Internet search engines are like virtual libraries. They look through all the websites out there on the internet and try to find information that answers your questions. You type in a question or a few words related to the topic you are looking for into the search engine, and it brings up a list of websites that might have the answer.
Libraries are places with lots of books, magazines and other materials that contain information. To get information from the library, you can look through books, ask a librarian for help, or use an electronic library catalog. The librarian or catalog can help you find books related to your topic.
