The MeSH on demand Tool is an easy way to identify relevant MeSH Terms – either for single terms, or for entire paragraphs. You just enter your terms or a paragraph in a box and click “Find MeSH Terms”. Why or when should you use this? If you are submitting an article for publication, you could paste text here and figure out which terms show up for each paragraph, and then choose the ones coming up most, as keywords. If you are looking for MeSH Terms to do a search, and do not find them in the MeSH Database, you may find the nearest ones here. The tool will definitely have more potential for uses in several contexts.
