2.62.6 Field 6 No Qualifiers: 20 characters, mandatory

Purpose: To specify the phrase for the condition of a holding using a subject heading, but without any subject heading qualifier. This phrase appears in the following scenario: if a user performs any subject heading search, when the user selects a specific subject heading, the software opens a window displaying the applicable subject heading qualifiers as found in the occurrences of the holdings. It is in this window that the phrase "no qualifiers" appears, representing holdings which use the subject heading without qualifiers.

Format: It is any characters but should be lower case.

2.62.7 Field 7 Sees: 14 characters, mandatory

Purpose: To specify the token to indicate a See relationship in the authority search displays.

Format: It can be composed of any characters.

Discussion: If a patron enters a search which results in an authority term which is a See, then the software display the transformation of the See to the correct term. For example, the subject heading search on HIV:

 Select from Exact Subject Headings "HIV".  
 -------------------------------------------------
  [?] HIV (20) 
  [ ] HIV-1 (2) 
  [ ] HIV-2 (2) 
  [ ] HIV Seropositivity (1) 
  [ ] HIV Infections (69) 
  [ ] AIDS-Related Opportunistic Infections (3) 
         = HIV-RELATED OPPORTUNISTIC INFECTIONS 
  [ ] AIDS Serodiagnosis (1) 
         = SERODIAGNOSIS, HIV 
         = HIV SERODIAGNOSES 
  [ ] AIDS Vaccines (1) 
         = HIV VACCINES 
  -------------------------------------------------
  [Main]  [Holdings]  [These]  [Help] 
  

Looking at the last listing, AIDS Vaccines, the search match is on the HIV in HIV Vaccines. But HIV Vaccines is now AIDS Vaccines, i.e., HIV Vaccines is a See to AIDS Vaccines.

Here, the equal sign is the token. Other reasonable tokens might be the words "used for", "is", "replaces", etc.

2.62.8 Field 8 MeSH Visual Cue {MeSH}: 14 characters, tab stop

Discussion: Many terms appear in LC, MeSH, and Other. Nevertheless, the terms are distinct, therefore the terms need visual cues indicating to which thesaurus they belong. For example, the term "Human Engineering" is found in both MeSH and LC. The following example shows how the visual cues works:

  
 Select from Exact Subject Headings "human engineering".  
----------------------------------------------------------------
   [ ] Human Engineering {Mesh} (5) 
   [ ] Human engineering {LC} (1) 
----------------------------------------------------------------
   [Main]  [Holdings]  [These]  [Help]

2.62.14 Field 14 Lower Case Bibliography Words: 13 characters, multiple

Purpose: To specify a list of legal lower case words in a bibliography title.

Format: It is any lower case words.

Discussion: MARC bibliographic records usually display a title with only the first word and proper names starting with an upper case letter. A formal bibliography formats only insignificant words as starting in lower case. This list of words is the words your system will allow to be lower case in a bibliography when they are not the first word in a title. Example: a, an, and, for, of, or, the, with
