The Big PictureWhy Learn about the information retrieval?
+Information Literacy
A few key information literacy performance indicators related to this workshop: Investigating the scope, content, and organization of
information retrieval systems Selecting controlled vocabulary specific to the discipline or
information retrieval source Constructing a search strategy using appropriate
commands for the information retrieval system selected (e.g., Boolean operators, truncation, and proximity for search engines.)

+Basics of Full-Text Retrieval Getting from a citation to the actual document.
+Setting up Google Scholar to Work with Hunter College Libraries
Start with Scholar Preferences
+Setting up Google Scholar to Work with Hunter College Libraries
In “Library Links” search for Hunter College Library and select
it.
+Retrieving Full Text from Google Scholar
Once your Scholar Preferences are configured, full text links at Hunter will display for available
articles.
+Verifying the Availability of Journals at Hunter Libraries
You can access a search of Hunter’s journal holdings through
this link.
+Verifying the Availability of Journals at Hunter Libraries
Details about online and print availability and coverage display
in the search results.
NOTE: This search is will not tolerate errors in spelling or
variations in wording.
+MeSH Terms and the Structure of MEDLINE
+
Here are four different interfaces that can be used to search the MEDLINE database:
+EBSCO
+OVID
+Web of Knowledge
+Pubmed
+
The basic structure of the MEDLINE database behind each of these interfaces is the same.
+Important Things to Understand about MEDLINE and PubMed:
All of the records in MEDLINE are indexed with NLM's controlled vocabulary, the Medical Subject Headings.
PubMed contains in-process citations which provide a record for an article before it is indexed with MeSH and added to MEDLINE or converted to out-of-scope status Citations that precede the date that a journal was selected
for MEDLINE indexing.
CONTENT of PubMed > Content of MEDLINE
+MeSH Terms?
MeSH is the National Library of Medicine's controlled vocabulary. It consists of sets of terms in a hierarchical structure that permits searching at various levels of specificity.
Example of the Hierarchical Structure of MeSH: Movement
Exercise Swimming
“Entry Terms” help guide queries to MeSH categories For example, “Vitamin C” is an entry term for “Asorbic Acid”
+Important Information Captured by MeSH Terms
Population Characteristics Age, Race, Country of Origin
Study Characteristics Clinical Trial, Literature Review, Meta-Analysis
Important Facets of a Major Topic Prevention and Control, Etiology, Genetics
+Features of the Ovid Interface
The Advanced Search offers you the option of selecting MeSH terms related to your search
terms.
+Features of the Ovid Interface
When selecting specific subheadings, the number of articles available under that
heading is displayed.
+Features of the Ovid Interface
Options for analyzing and manipulating your search history are accessible on the same page
as your search results.
+Features of the Ovid Interface
You can export a formatted bibliography into Word, PDF, or a
citation manager.
+
Boolean LogicThe structure of a MEDLINE query
+Using Boolean Logic to translate a topic into a search query:
Statement of Topic or Research Question
Keyword 1 Keyword 2 Keyword 3
(A OR B OR C) AND (D OR E OR F) AND (G OR H OR I)*
*Where A – I are terms related to the keywords above
