Books: Citation information, such as title, author, publisher, place of publication, and publication date, are available in the record for the book in the library catalog.
Journal articles: look for "citation tools" or "cite this article" or something along those lines in the database. If the database doesn't offer citation help, you can usually find all of the information (title, author, journal, issue...) at the very top of the article page.
