1. LIBRARY RESOURCES &
THE LITERATURE
SEARCH

2. What do we learn by searching the literature?
• Search the literature helps us:
• understand a topic
• help you form a research question
• provide confirmation of an already existing
hypothesis
• analyze and interpret your own data
• gain exposure to past, current, and ongoing
research about a subject you are exploring
for research of your own

3. The Literature Search Process
Identify a research topic or question1
Decide where to search2
Use scholarly research tools to find sources3
Identify, revise, or reiterate research question4

4. Identify a research topic or question1
Decide where to search2
Use scholarly research tools to find sources3
Identify, revise, or reiterate research question4

5. • Good research topics are
• Specific
• Coherent
• Researchable (within your timeframe)
• Developing a research topic is research
Identify a research topic or question1

6. Identify a research topic or question1
How is machine learning used in remote sensing
applications?
How is machine learning used to for image
classification in remote sensing applications?

7. The Literature Search Process
Identify a research topic or question1
Decide where to search2
Use scholarly research tools to find sources3
Identify, revise, or reiterate research question4

8. Decide where to search2
• Peer-reviewed journal
articles
• Books
• Reference works
(encyclopedias, textbooks)
• Research Data
• Gray literature
• Reports (government, industry,
non-governmental
organizations)
• Theses & dissertations
• Conference proceedings
Types of scholarly information

9. Decide where to search2
OneSearch
Not a library database, searches
across library databases and the
physical holdings
Not discipline-specific

10. Decide where to search2
Library Databases
Usually focused on a single discipline
Use for finding scholarly articles

11. Decide where to search2

12. Decide where to search2
Research Guides
Collections of relevant
databases, books and
websites focused on
an academic program
or course

13. Decide where to search2

14. Decide where to search2
Choosing databases

15. The Literature Search Process
Identify a research topic or question1
Decide where to search2
Use scholarly research tools to find sources3
Identify, revise, or reiterate research question4

16. Use scholarly research tools to find sources3
• A database is a search tool for finding scholarly literature
• It is generally focused on scholarly journals within a single
discipline
• Sometimes databases contain the full text of a journal article,
but they often do not
What is a library database?

17. Use scholarly research tools to find sources3

18. Use scholarly research tools to find sources3

19. Use scholarly research tools to find sources3
Good keywords are:
• Words that will commonly be used to discuss the topics that
you are interested in researching in academic or technical
settings
• Specific to your topic, rather than commonly used to describe
many topics
• “cause” and “result” don’t make good keywords
Choosing Good Keywords

20. Use scholarly research tools to find sources3
Breaking down your research question
