An encyclopedia is used when someone wants to find information about a person, place, or thing.

Many people use an atlas when they are going on vacation or traveling to another place.

5. Dictionary We use a dictionary to look up words.
You will find the meaning of words in a dictionary.
For example, when you do not know the meaning of a word in a story. You may use a dictionary to look up the meaning of the word.

6. Thesaurus In a thesaurus, you will find synonyms for words.
First, you look up the word in the thesaurus. Next to the word you will find a list of words that mean the same things as the word you looked up.
Like wonderful –great, magnificent, excellent, terrific, cool, and fantastic
Also in a thesaurus you will find an antonym for the word. Like horrible or awful would be an antonym for wonderful.
