This document provides an overview of concepts and skills for information retrieval and literature research. It discusses the importance of information literacy and introduces databases like MEDLINE, PubMed, EBSCO and Ovid that can be used to search for medical literature. It explains how Medical Subject Headings (MeSH) are used to index articles in MEDLINE and highlights features of the Ovid interface like selecting MeSH terms and exporting bibliographies. Finally, it demonstrates how Boolean logic can be applied to construct search queries using keywords related to a topic or research question.

- 13. + Here are four different interfaces that can be used to search the MEDLINE database:
- 14. + EBSCO

- 19. + 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.

- 20. + 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”
