General Notes

String multiple occurrences with a semicolon unless indicated otherwise. If the source data has a period at the end and it is not the final occurrence, remove the period.
Remove the following end punctuation: : , = ; /

Notes Regarding Subfields and Indicators

If no subfields are listed explicitly, data from all non-numeric subfields will be displayed.
If a field or a subfield is repeated, all instances should be displayed.
Subfields are listed in alphabetical order for the sake of clarity, but should be displayed in the order they are recorded in the source record.
If all the subfields or specified non-numeric subfields are taken, numeric subfields are not considered.
If a numeric subfield is specifically included, no other numeric subfield will be included.
If a numeric subfield is excluded, the mapping will take other numeric subfields.
If no indicators are defined, all indicators will be taken.

880 tags are mapped together with the standard tag (the 880 tags are added first) in the following fields: Contributor, Publisher, Creator, Description, Edition, Subject (for 600, 610, 611, and 630), Relation, and Is part of.

Generic MARC 21 Display Section
Display Element	Source	Note
Source	Source from the data source definition
Resource Type	See mapping below
Title	If FMT=SE, then use 130 OR 245; otherwise use 245 with the following subfields: 130 ##adfklmnoprs 245 ## $$abfgknp	The 130 was added for serials, because for serials additional information will typically be in 130.
Uniform title	130 admnprs OR 240 admnprs
Vernacular title	880 where $$6=245 subfields: abfgknp
Creator	100 abcdejqu 110 abcde 111 abcdn	If the creator is derived from 100 and the first indicator is 1 or 2 then all of the text after the comma is taken (there must be a comma) and is displayed before the text that precedes the comma (deleting the comma itself). For example: Lippe, Ole von der --> Ole von der Lippe Van Der Wise, Fred --> Fred Van Der Wise Disabled rules do not reverse the author name.
Contributor	700, 710, and 711 except for second indicator=2 With the following subfields: 700 abcdejqu 710 abcde 711 abcdn	For 700 the first indicator is 1 or 2. Therefore all of the text after the comma is taken (there must be a comma) and is displayed before the text that precedes the comma (deleting the comma itself). For example: Lippe, Ole von der --> Ole von der Lippe Van Der Wise, Fred --> Fred Van Der Wise Analytic 7XX field are excluded. They will be added to the description. Disabled rules do not reverse the author name.
Description	505, 520 $a 700, 710, and 711 with the second indicator=2 using the following subfields: 700 abcdemnopst 710 abcdemnopst 711 acdenpqst	Every field is a separate occurrence.
Edition	250 $a $b
Publisher	502 a or 260 a,b or 264 a,b And equivalent fields from 880.
Subject	All 6XX fields	Strip all numeric subfields.

Physical Format	300 and 340 fields	If the 300 field does not end with a period, add it.
Identifier	020 $$a – prefix the value with ISBN: 022 $$a – prefix the value with ISSN: 024 2# $$a – prefix the value with ISMN	This mapping is disabled in the out-of-the-box template since the identifiers by default do not display in the Front End.
Relation	Prefix the value with Series: 400, 410, 411, 440, 490, 800, 810, 811, 830, 840 780 (first indicator -1): Prefix the value with Earlier Title: 785 (first indicator -1): Prefix the value with Later Title: Strip subfield $w, $x, $y	Every field should be a separate occurrence. The prefix should be added to $$C and the value to $$V. Display constant codes are used: series earlier_title later_title
Is Part Of	773 Strip subfield $w, $x, $y
Creation Date	260 $c OR 008/07-10	For a date created from 008, create a date only if it starts with a digit that is not zero and replace missing digits with a question mark. For example: 19-- > 19?? 19uu > 19??

Duplicate Record Detection Vector

Currently two types of record matching vectors exist:

T1 – for non-serials
T2 – for serials

The mapping of record to T1 or T2 is based on the format type. The format type is based on the extraction procedure that creates the format (FMT) field from pos. 6 and 7 in the leader.

T1 – All formats except for SE
T2 – SE

Vector for T1 - "non-serials"

Special character	Special meaning	Entity encoding
>	Begins a tag.	>
<	Ends a tag.	<
Quotation mark.	"
	'Apostrophe.	'
&	Ampersand.	&

The publishing platform removes all leading and trailing spaces and packs double spaces.

Normalization Routine #1

Remove non-filing characters

Drop initial text using non-filing indicator. The non-filing indicator is the second indicator in the following MARC tags: 222, 240, 242, 243, 245, 440, and 830. The second indicator contains a number from 0-9 indicating how many characters to drop. (There are some fields where the non-filing indicator is in the first position: 130, 630, 730, and 740.)

Remove all text that appears within <<>> or within the Unicode characters 0088 and 0089.
Delete the following characters: '
Change the following characters to blank: !@#$%^&*()_+-={}}[]:";<>?,./~`
Convert characters using the "FILING-KEY-01' character conversion table.
Change characters to lower case.
Remove all spaces.
Take first 10 and last 10 characters.

Normalization Routine #2

Remove non-filing characters.

Drop initial text using non-filing indicator. The non-filing indicator is the second indicator in the following MARC tags: 222, 240, 242, 243, 245, 440, and 830. The second indicator contains a number from 0-9 indicating how many characters to drop. (There are some fields where the non-filing indicator is in the first position: 130, 630, 730, and 740.)
Remove all text that appears within <<>> or within the Unicode characters 0088 and 0089.

For example:

<datafield ind1="1" ind2="0" tag="245"> <subfield code="a"><<the>> book : its history in England in the middle ages!</the></subfield> </datafield>

Should become:

"book: its history in England in the middle ages"
Delete the following characters: '
Change the following characters to blank: !@#$%^&*()_+-={}}[]:";<>?,./~`
Convert characters using the "FILING-KEY-01' character conversion table.
Change characters to lower case.

Normalization Routine #3

Delete the following characters: '
Change the following characters to blank: !@#$%^&*()_+-={}}[]:";<>?,./~`
Convert characters using the "FILING-KEY-01' character conversion table.
Change characters to lower case.

Normalization Routines for FRBR

Remove non-filing characters.

Drop initial text using non-filing indicator. The non-filing indicator is the second indicator in the following MARC tags: 222, 240, 242, 243, 245, 440, and 830. The second indicator contains a number from 0-9 indicating how many characters to drop. (There are some fields where the non-filing indicator is in the first position: 130, 630, 730, 740.)
Delete characters: | [ ] '
Change characters to space: $~'^%*/\?@.:;<>{}}-()"!¿¡
Convert characters using the NACO_diacritics character conversion table.
Change characters to lower case.

Defining the Delivery Category Algorithm

The following out-of-the-box algorithm is used for MARC 21. It should be possible to distinguish between the following resource types:

Physical items (except for microfolm)
Microform
SFX resources
Online resources

The algorithm is read from top to bottom. Once a record is assigned a category, the algorithm stops.

When there are several definitions for the same category the priority is given to the "safest" option.

In the algorithm, priority has been given to online resources based on the assumption that users most often prefer this option. Primo will include a display of the location and availability status of physical items.

The format is based on the definitions used for each resource type. For more information on these definitions, see LDR Positions.

Defining the Delivery Category Algorithm
Condition	Delivery Category	Note
If 035=SFX	SFX Resources
007/00=c and 007/01=r	Online Resource
If there is a 8564- or 85640 or 85641	Online Resource	Add conditions based on $$3 to prevent this category from being assigned if the link is not to the resource (e.g. $$3 is Table of Contents, or Abstract).
If 007/00=h	Microform
If FMT=BK or MU or SE or MX and 008/23=a or b or c	Microform
If FMT=MP VM and 008/29=a or b or c	Microform
If 245 $$h includes the string micro	Microform
If not any of the above	Physical Item
