+ Overview The Big Picture Basics of Full-Text Retrieval at Hunter MeSH Terms and the Structure of MEDLINE Boolean Logic
+ The Big Picture Why 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.) “Information Literacy Competency Standards for Higher Education”(2000) http://www.ala.org/acrl/standards/informationliteracycompetency.
+ 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.
+ 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 NLMs 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 Medicines 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 Logic The 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
