Study Notes
Medline and MeSH
- Medline is a comprehensive database of biomedical literature, indexing over 29 million records from more than 7,000 journals.
- MeSH (Medical Subject Headings) is a controlled vocabulary thesaurus used to classify and index biomedical literature, facilitating accurate and consistent searching of Medline.
Medline Search Operators
- The 'AND' connector in a Medline search narrows the search results by requiring the presence of both terms on either side of the connector, resulting in a more specific and precise search.
- The 'OR' connector in a Medline search broadens the search results by including records that contain either term, increasing the number of retrieved results.
Databases vs. Internet Resources
- Databases, such as Medline, are structured collections of organized information, often with controlled vocabulary and indexing, which enable precise and efficient searching.
- Internet resources, on the other hand, are unstructured and unindexed collections of information, often requiring more effort and time to find relevant information.
