What are they? KeyPhrase Headings • Keywords and Phrases from • Title, Abstract, Full text, Indexers’ expertise • Reflect the most important concepts
Key Benefits KeyPhrase Headings • Include implied concepts • Additional information from full text • Include topics not yet in Thesaurus • Search general but relevant topics (GaP, trees, impact…) • Search topics very common on Inspec (data, computers…) • Exclude topics that are only mentioned
Free Language Search Searching Title, Abstract, Key Phrase Headings Problems: Variations in spelling, acronyms and abbreviations
