Specifying Conditions on an Extraction Tag

You can specify a condition to any of the extraction tags that you set up in a MARC map. (An extraction tag is the tag you want the MARC map to “find” and extract data from.)

For example, you can set your Display MARC map to extract and display additional title data from the 210, 212, 222, 246, and 740 tags, but to extract and index data in the 246 tag only if indicator 2 of tag 246 has specific values. In this case, the MARC map will still index the other tags you set up as extraction tags regardless of the values in those tags. Here is an example of this MARC map setup:

Extract data in 246 tag only if indicator 2 has a value of 0 through 3.
