What are reference tools?
Reference sources are authoritative works that you can refer to for specific answers or information. There are many types of reference sources, including dictionaries, encyclopedias, thesauri, directories, and almanacs. But in broader terms, reference works can also include materials such as bibliographies, handbooks, atlases, gazetteers, style manuals, or statistical sources.
