3. Thesaurus
 Comes from Greek thesauros, meaning
"storehouse, treasury," and its original sense was
"dictionary or encyclopedia," but this was
narrowed to the current meaning with the
appearance of Roget's in 1852.

4. First English language thesaurus
(the 'Roget's Thesaurus') was
created in 1852 by the UK surgeon
Dr. Peter Mark Roget (1779-1869).
The term is derived from the Greek
word 'thesauros,' treasure.

5.  Unlike a dictionary (which is organized to help in
finding the meaning if you know the word), a
thesaurus requires you to know the intended meaning
to help find the correct word.
 Unlike a dictionary of synonyms (which is an
alphabetical list of related words) a thesaurus
is structured around ideas and serves as a
treasury of knowledge.
Thesaurus differs from a
Dictionary…

19. ATLAS
An atlas is a collection
of maps; it is
typically a map of
Earth or a region of
Earth, but there are
atlases of the other
planets (and their
satellites) in the
solar system.

20. An atlas is a collection of maps compiled into an
easy-to-use format. It usually has an
accompanying gazetteer, which is an alphabetical
listing of place names and their pronunciations.
Atlases may be general in nature and cover the
entire globe, or they may be specific to
geographical locations, topics or time periods.

21. Uses of an Atlas…
1.Finding place in the map
2.Measuring distances
3.Determine direction
4.Understand map symbols

22. How to use
an atlas?

23. 1. Choose an atlas that has the information you need.
If you need current maps, an historical atlas is not
the best choice.
2. Make sure the copyright is current, if you use an
atlas for driving directions. Road map atlases
become dated within a matter of years.
3. Determine the layout of the atlas. Look at the
introductory material. Note the basic geographical
definitions you are given. This helps you interpret
the maps.
4. Study the key or legend to the maps. Each publisher
uses different symbols, so it's important to know
what you are looking at on the maps.

24. 5. Use the table of contents to find maps for your
research. You can find entire groups of maps you
can use here.
6. Reference the index or gazetteer too. This is
normally found in the back of the atlas, although
some publishers place it in the introductory
section. The index or gazetteer gives the page
numbers of the maps you are looking for. Along
with the pronunciation of the place name, it
gives you longitude and latitude coordinates as
well.

25. Just like the Atlas, May we be
an instrument to guide our
future students toward the
right direction and right
path.
God Bless Us! 
