DictionariesThesaurusEncyclopediaAtlasAlmanacPeriodicals

Dictionary

Dictionaries are used to look up words. They can be used for a variety of

reasons: Definition Spelling & pronunciation Word origin Part-of-speech

There are also many different types of specialized dictionaries such as a Biographical or Geographical dictionary.

Biographical Dictionary

Biographical dictionaries are used to find information about famous people.

They usually contain brief facts about the person’s life such as: birthdate, major accomplishments and events that have made the person famous.

If you wish to find MORE information, you will need to go elsewhere.

Geographical Dictionary (Gazetteer)

Geographical dictionaries contain information about places. They ARE NOT, however, a book of maps.

Geographical dictionaries provide information about a place such as location, population, industry and famous landmarks.

The information is very brief but will provide you a starting point to go elsewhere for additional information.

Thesaurus

A Thesaurus is used to find words that mean the same or opposite as another word.

These are called synonyms and antonyms.

They are simple to use - just look up your word and a thesaurus will give you the list of synonyms and antonyms for that word.

A Thesaurus, however, DOES NOT usually provide you with a definition (you need a dictionary for that).

Encyclopedia

An Encyclopedia is used to find information about a person, place, or thing.

Articles found in an Encyclopedia are usually longer and contain more information than a Dictionary.

Encyclopedias are a great place to start to find information about a topic you know nothing about, but are not usually accepted as a source for high school students.

Example: Wikipedia!

Atlas

An Atlas is a book of maps. Atlases are used to find specific

locations such as: country, state, city or geographic formation.

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

There are also specialized atlases such as historical and geographic.

Almanac

An Almanac is a book of facts that provide brief, useful and interesting information relating to countries of the world, sports, entertainment, etc.

They are updated every year so they always contain the most current information available.
