NLM LocatorPlus -- MARC Search Fields


Question: When I do a search in LocatorPlus, exactly which MARC fields are being searched?


Answer:


Simple Search

Here are some details on how some of the different Simple Search types are set up:

  • - Keyword Searches
    • - Title does a phrase search in a composite Title Index; all entered words must be adjacent words from the same subfield.
  • - Left Anchored Searches
    • - Journal Title Search searches a composite Journal Title/Title Abbreviation Index
    • - Subject Search searches the subject authority file
    • - Author Search searches the name authority file
    • - Call Number Search searches the Call Number from the Holdings record

 

Here are the MARC fields that are searched for each of the search types:

Items marked with ** are NLM Applications of MARC 21
