Changing or Creating a MARC Map

You can set up MARC maps for indexing, display, limiting, or linking. This section explains how to set up each type of these MARC maps. (For more information on each type of MARC map, see MARC Maps.)

To change or create a MARC map

View: marc_map
Process: Administration\Index Control Menu\MARC Map Table

1 In these fields, do the following:

Field

Action

Marc_map Code

Enter the code that identifies the MARC map.

Important: Use the prefix suggestions listed in the table under Default MARC Maps as a guide in naming your MARC maps.

Description

Enter a description of the MARC map.

For example, you may name the MARC map “Stitle” if you are creating a MARC map to extract titles for keyword indexing.

Search Limit?

Do one of these options:

Mark this box if you are creating a search Limiting MARC map.
Clear this box if you are creating an Indexing, Display, or Linking MARC map.

Sort Filter

Do one of these options:

If you do not want to filter the data this MARC map extracts, mark No Filter.
If the data that this MARC map extracts is date information, such as publication dates, mark the Year (4 digits) option if you want Horizon to sort and display the year in four digits.
If the data that this MARC map extracts is numeric information, mark the Numeric Value (decimal optional) option if you want Horizon to sort and display the numeric value.

Run-on

Do one of these options:

If you want to display one line per tag, mark Do Not Run-on option.

Generally, you will want all types of MARC maps that you create to display one line per tag.

If you want to display tags in MARC maps as a single string instead of one line per tag, mark Do Run-on.

For example, if you want your Bibliographic Detail window in staff searching and PAC to display all additional titles as a run-on line instead of displaying one title per line, you can create a 7xx MARC map with Do Run-on marked.

Note: The One Tag Only check box in the mq_index view specifies that only the result of the first tag is considered, so if the One Tag only box is marked, Horizon disregards the Run-on setting.

2 In these fields, do the following:

Note: For more information on completing this Extraction group, see Understanding Conditional Parts of a MARC Map.

Field

Action

Tag

Enter the tag that you want the MARC map to extract information from.

For example, if you are creating an Indexing MARC map to extract author information, you would enter “100” as the tag.

Part

Enter the subfields or fixed field positions of the tag that you want the MARC map to extract information from.

For example, if you are creating an Indexing MARC map to extract author information, you may enter “abcdfgklmnopqrst”.

Conditional Part

Enter which part (subfield or fixed field position) must contain the conditional value in order for Horizon to extract the MARC information, only if you want to set a condition on the tag you are extracting.

Note: Entering conditions requires that you specify characters, such as the slash (/) before a position, and so forth. (For a list of conditional characters, see Conditional MARC Map Syntax. For an example of how a conditional character can be used, see Example of a MARC Map with Conditionals .

Conditional Value

Enter the value that the conditional part (subfield or fixed field position) must contain in order for Horizon to extract the MARC information, only if you want to set a condition on the tag you are extracting.

First Tag: Prefix

Do one of these options:

If you want a constant string of characters to display before the first displayed tag, enter the string in this field.

Typically, you would only want to display a prefix if you are setting up a Display MARC map.

If you do not want a string of characters to display before the first tag, leave this field empty.

First Tag: Suffix

Do one of these options:

If you want a constant string of characters to display after the first displayed tag, enter the string in this field.

Typically, you would only want to display a suffix if you are setting up a Display MARC map.

If you do not want a string of characters to display after the first tag, leave this field empty.

Other Tags: Prefix

Do one of these options:

If you want a constant string of characters to display as a prefix before other displayed tags, enter the string in this field.

Typically, you would only want to display a prefix for other tags if you are setting up a Display MARC map.

If you do not want a string of characters to display as a prefix before other tags, leave this field empty.

Other Tags: Suffix

Do one of these options:

If you want a constant string of characters to display as a suffix after other displayed tags, enter the string in this field.

Typically, you would only want to display a suffix for other tags if you are setting up a Display MARC map.

If you do not want a string of characters to display as a suffix after other tags, leave this field empty.

HTML Format (Info Portal only)

If the Display MARC map that you are setting up is for setting up linking tags that display URLs or other information in Information Portal, such as the 856 tag, enter the format for the link in this field.

For more information on setting up Information Portal to use 856 tags [Linkable Tags], see the Information Portal System Administrator’s Guide.

Distinct Subfields

Do one of these options:

If you want Horizon to treat each subfield in the extraction tag you are setting up as a separate entry in the index or as a separate line in your display, mark this box.

This option is specifically for Indexing and Display MARC maps. (For example, this feature lets you make full use of the enhanced content notes in the 505 tag.)

Note: If you mark this option, you must make sure the Do Not Run-on option is also marked for this MARC map.

If you want Horizon to treat all subfields as one entry, clear this box.
3 In these fields, do the following:

Note: For more information on completing this Conditional group, see Understanding Conditional Parts of a MARC Map.

Field

Action

Opening Paren.

If you are grouping several conditions in this MARC map together, enter a left parenthetical mark in the first entry for the group.

Tag

Enter the tag that you are setting up as the conditional tag.

For example, if you are creating an Indexing MARC map to extract a main or added entry tag, but only if position 14 of the 008 contains a value of “a”, you would enter “008” as the tag.

Part

Enter the subfields or positions of the conditional tag you want the MARC map to extract information from.

For example, if you are creating an Indexing MARC map to extract a main or added entry tag, but only if position 14 of the 008 tag contains a value of “a”, you would enter “/14” as the part.

Value

Enter the value that the conditional part (subfield or position) must contain in order for Horizon to extract any of the MARC information specified for the entire MARC map.

Closing Paren.

If you are grouping several conditions in this MARC map together, enter a right parenthetical mark in the last entry for the group of conditions.

Operator

If you are creating several conditions in this MARC map and you want to use operators to relate the conditions together, do one of these options:

Mark None if you are setting up only one condition on this MARC map.
Mark AND if you are setting up multiple conditions on this MARC map and want to require that all the conditions must be met in order for the MARC map to extract any data from the extraction tags.
Mark OR if you are setting up multiple conditions on this MARC map and want to require that only one of the conditions must be met in order for the MARC map to extract any data from the extraction tags.
