Library of Congress MARC 21 Bibliographic Data at

http://www.loc.gov/marc/bibliographic/

Provides access to both the full and concise versions of the MARC 21 Format for Bibliographic Data

To learn the Marc tag, it is good to start with Tag 100:


Main Entry-Personal Name

to learn more about Tag 100, click the link, and have a look at the first indicator, e.g.,

First Indicator  
Type of personal name entry element
0 - Forename
1 - Surname
3 - Family name

then try to understand some subfield codes, e.g.,

Subfield Codes
  • $a - Personal name (NR)
  • $b - Numeration (NR)
  • $c - Titles and words associated with a name (R)

Dear Ms Dexterine Ho

Thank you for the post on Tag 100. Have a question regarding Tag 650:

For the first indicator, does (1) refer to Primary school level and (2) refer to Secondary school level?

Thank you for your attention.

Sincerely,
Benjamin Wong

Thank you for the clarification. However, as the OPAC record does not indicate if the subject is of primary or secondary importance, is it best to leave the first indicator blank?

Take for example:



There are three subjects, Leadership, Mathematics and Science, but which of them are Primary/Secondary?

You are right: the OPAC record does not indicate if the subject is of primary or secondary importance.

But it is good to the code first indicator, if your are able to.

If you are not sure, it is OK to leave it blank.
