Recap
Systematic Literature Review
• Formulate the research question(s): Select a topic
and set criteria (inclusion/exclusion)
• Search the literature
• Gather, read, analyze and assess quality of results
• Search and refine
• Write and reference
Types of Sources
• Primary sources: a report by the original
researchers of a study
• Secondary sources: description or study by
someone other than the original researcher (e.g. a
review article)
• Conceptual/theoretical: papers concerned with
analysis of theories associated with the topic
• Anecdotal/opinion: Views about the subject that
are not research, review or theoretical in nature
Types of Sources
• People: experts in the area
• Journals: current, scholarly work
• Major books or monographs: good overviews,
good treatment of history
• Dissertations: literature reviews
• Encyclopedias: general reviews
• Web based material: overviews
• Collections of images or objects
Finding Journal Articles
• UW-Madison Libraries have licensed many databases for your use
• Information cannot be accessed by using Google (most is proprietary)
• After finding specific articles, search for the journal title in MadCat for
location on campus
• Some databases may have links to full-text via
• Links to databases from our home page
• By subject or name from E-Resource Gateway
• Remote access: http://www.library.wisc.edu/help/remote/remoterestrict.html
Searching
• Plan your search
• Remember variant word endings, Boolean connectors and synonyms
• Limit search terms to specific fields (title, subject heading), within a
certain proximity to each other, year ranges
• To narrow a search: limit by theoretical approach, one aspect of
subject, by time, by geographic location
• To broaden a search: generalize your topic, check more databases,
limit jargon, check Web or newspaper databases if topic is too new
• Note controlled vocabularies
• Perform search, review results, refine search, search again, refine
search, search again, export results
Subject Databases
• Meteorological and Geoastrophysical Abstracts
(MGA)
• Oceanic Abstracts
• NTIS
• Web of Science
Meteorological and Geoastrophysical
Abstracts
• Updated quarterly, 1960 –
• MGA covers meteorology, climatology, oceanography,
remote sensing, atmospheric chemistry, hydrology, etc.
• Indexes journal articles, conference proceedings, books,
technical reports
• Includes abstract for most entries
• Includes links to full-text for AMS journals and other
journals if the campus has a license
• Pre-1960 literature can be found using print
equivalent
Oceanic Abstracts
• Updated monthly, 1984 –
• Premier database for marine resources
• Covers biology, ecology, marine geology,
geophysics, geochemistry, oceanography, marine
pollution, environmental protection
• Includes links to full-text where available
• Same interface as MGA, NTIS and Oceanic
Abstracts
NTIS Bibliographic Index
• Updated quarterly, 1964 –
• Contains descriptions of U.S. government sponsored
sci/tech research from DOD, DOE, EPA, NASA, NOAA…
• Covers astronomy, atmospheric science, biotechnology,
computers, energy, engineering, etc.
• Included are: reports on contracts/grants, technical
memoranda, technical reports, dissertations, etc.
• Pre-1964, consult Government Reports and
Announcements Index in print
• Same interface as MGA
Characteristics of Government Documents
• What are they? Conference literature, government reports, internal
reports, reports on contracts, etc.
• Why are they important? Cited in literature and historically have
provided a rapid means of scientific communication.
• Who publishes them? Agencies, governmental bodies, professional
societies, federal contractors, etc.
• What characteristics do they have? Alpha-numeric report numbers,
accession numbers, grant or contract numbers, sponsoring agency, no
commercial publisher, distributed through facility like NTIS.
• Where can I find them? 1)Libraries: Campus libraries have most
reports distributed 2)NTIS, DTIS, NASA, STI 3)Author
4)Issuing agency
Web of Science
• Updated weekly, 1970 –
• Combination of three databases
• Indexes peer-reviewed journal literature only – does not
include reports, conference proceedings, dissertations…
• Known for its currency and meticulous indexing
• Used to do general, cited reference or author searching
• Journal Citation Reports is companion database:

Nino Southern Oscillation).
• Who published the first critical papers?
• How has the theory developed?
• Synonyms: ENSO, El Nino Southern Oscillation,
history, bibliography, tropical ocean circulation,
phenomena, theory, reviews

for papers before 1986
Compare information from sources
• 1891: Dr. Luis Carranza, Lima Geographical Society, contributed a
small article to its Bulletin, noting a countercurrent flowing from north
to south along points on the coast of Peru – first recorded observations.
Named El Niño
• 1923: Sir Gilbert Walker names the Southern Oscillation by
recognizing that changes across the tropical Pacific were not isolated
phenomena but connected as part of a larger oscillation
• 1969: Jacob Bjerknes, UCLA, first real description of El
Niño/Southern Oscillation in terms of physical mechanisms
• 1970s-1980s: S.G.H Philander and K. Wyrtki continue to expand the
concept
• 1990s
