Best Practices for NET Holdings for Locally Digitized Materials

Introduction and Background Information

Introduction 

The purpose of this wiki is to assist Harvard Library units involved in creating MARC 21 Networked Resource (NET) holdings for locally digitized materials by providing MARC field-by-field instructions, documentation, and format specific templates and examples following recommended Harvard best practices for cataloging. These recommendations are for prospective cataloging. Individual units can decide how or if to apply these best practices retrospectively. 

These best practices are based upon the Multiple Record Implementation Task Group’s (MRITG) recommendation (Jan. 29, 2020) that Harvard continue to use a single record approach for describing locally reformatted materials while we remain in a MARC-based cataloging environment. For more information on Harvard’s historical cataloging practice using the single record approach see: Technical Services Single Record Approach Vs. Multi-Record Approach.

Imaging Services documentation for NET holdings metadata best practices (historical document) has existed for local use, but needed to be updated to cover more formats and incorporate RDA. The following templates and field by field instruction outline a best practice to more accurately set holdings on the correct format in OCLC. Coding and wording in the templates represent collaboration among staff from across library units experienced with creating NET holdings and in consultation with Library Technology Services (LTS) and the Metadata Standards Working Group (MSWG). NET holdings examples are not necessarily representative of up-to-date practice. However, new Alma templates are available in the Alma MDE for units to copy and customize. 

These guidelines take into account the wide range of material reformatted on Harvard’s behalf (e.g., print, manuscript, photographic, sound, video); legacy reformatting and current reformatting performed by Imaging Services, Media Preservation Services, and outside vendors; digitization projects with external partners such as the Biodiversity Heritage Library (BHL); digitization done for preservation and that is done solely for access; and digitization of whole or parts of a work or collection.

If there are any specific special collections or sets of records that are problematic for users/staff with regard to the single record approach, units are encouraged to submit a ticket to the LTS Alma Support Center http://nrs.harvard.edu/urn-3:hul.ois:almasupport with category “Resource Management” to pursue solutions on an ad hoc basis. 

For questions or additional assistance in creating NET holdings records for locally digitized materials, please consult staff in Imaging Services [ksweeney@fas.harvard.edu]

Partially and Completely Digitized Works and Collections

Multipart Monographs, Serials, etc.

Refer to Harvard Library MARC Holdings Examples for best practices for 853/863 fields and see recommendations in the Field-by-Field Instructions below for fields 843 and 856.

Archives and Manuscript Collections 

In addition to linking directly to locally digitized material through finding aids (i.e., HOLLIS for Archival Discovery), repositories are also encouraged to use NET holdings. Alma records with NET holdings and a 856 field first indicator 4 and second indicator 1 will display with the link “Online Access” for better access for researchers. (See Online links in HOLLIS search results (Library Catalog scope) for more information.) 

Repositories can take one of several approaches when using the 856 field to link to digitized material in collections (see the 856 field below for more information):

• link directly to the digitized material using one or more 856 fields, 

• link directly to a PDS (Page Delivery Service) Document List (see Creating PDS Document List Object Batches for more information)

• link indirectly to a finding aid with links to locally digitized material using one 856 field.  

Using the third approach would require no maintenance of the holdings record as additional material in the collection is digitized over time. Repositories can choose the right approach for their collections. 

Using a NRS persistent identifier (i.e., URN) or the HOLLIS for Archival Discovery permalink (i.e., begins with ids) in the 856 subfield $u is also strongly recommended.

Registry of Digital Masters (RDM)

NET holdings created for print monographs and serials for various Harvard Library digital preservation projects and programs conform to full Digital Library Federation (DLF) specifications. In the past, a location code of RDM was used to indicate records being exported to Digital Library Federation/OCLC Registry of Digital Masters. The Registry ceased operations sometime after 2011. Harvard Library has continued to follow DLF specifications and uses the RDM code when creating NET holdings for these materials.

Digital Library Federation (DLF) specifications require the following eight fields in addition to typical bibliographic metadata:  007, 042, 506, 533, 534, 538, 583, 856.

In accordance with the decision to continue using the single record approach for locally-digitized materials, the following six fields are required for holdings records:

• 007 Physical description fixed field: Electronic resource 

• 506 Restrictions on access note 

• 538 System details note 

• 583 Action note

• 843 Reproduction note

• 856 Electronic location and access
  

FYI: Field 972 is no longer exported to OCLC, but it is still a reportable field in Alma Analytics Physical Items > Holding Details > Local param 06.

In addition, Alma collection code RDM in 852 $$c is used to identify a digital master.

Imaging Services adopted Digital Library Registry (dlr) specifications on 5/10/07. All NET holdings created by Imaging Services since that date follow full dlr specifications as contained in the Registry of Digital Masters. Record Creation Guidelines. Version 2. May  2007. The wording in field 506 was further revised in the NET holding per star specifications on 12/5/08. (star = Registry of Digital Masters. Standardized Terminology for Access Restriction. Rev. March 23, 2007).

Export to OCLC 

These best practices are in alignment with the criteria for publishing locally digitized holdings to OCLC. A subset of fields from the Alma holdings record are converted to equivalent bibliographic fields and reported to OCLC, e.g., the 843 field is converted to the 533 and 539 fields.  Note on the use of subfield $5 in holdings: OCLC Data Sync will apply subfield $5 MH to fields 506, 538, 583, 843 upon export. For prospective cataloging, the subfield $5 is not required for these fields in Alma. 

Notes referencing the criteria for syncing are included in the field by field guide. Staff are encouraged to consult the 2019 OCLC Data Sync Project information page on Alma publishing for Bibliographic Data Sync for more detailed information, including the normalization rules for creating the new bibliographic record for the digital version.

Example 8: Multipart print map monograph (composite stitched image)

For multi-sheet maps where the component sheets can be assembled to form a single map, in some cases, Imaging Services has provided a digital version of the resource that is a single digital image where all the component map sheets have been digitally combined together to form one seamless image (stitched). In these cases, The Map Collection creates a single NET holdings record for the stitched version of the map (intended for public display). Example of a stitched image compiled from 4 source map sheets: http://nrs.harvard.edu/urn-3:FHCL:4420936?buttons=y

• Local Param Fields in Analytics - Mapping Guide 

• Harvard Library MARC Holdings Examples 

• MARC21 for Holdings

506 (Restrictions on Access Note)

http://www.loc.gov/marc/holdings/hd506.html 

Use to indicate whether access is open to the public or restrictions apply.

Use standardized terms in the subfield $f from Standardized Terminology for Access Restrictions (star). Use the language commonly in use at Harvard in the $$a for unrestricted materials in order to sync to OCLC (see Alma Publishing for Bibliographic Data Sync Reclamation and Cataloging policies and practices for Data Sync) and for restricted recommend using language that won’t become outdated.

OCLC Data Sync: Holdings with 506 field indicating access to resource is unrestricted will export to OCLC (1st indicator 0 and field's text contains 'Unrestricted' or 'unrestricted').

Related Harvard Documentation: Best practices for MARC 21 fields describing local information

1st indicator = 0 Indicates that access is open to the public 

1st indicator = 1 Indicates that restrictions apply

Examples:

506 0# $$a No restrictions on access copy. $$f Unrestricted online access $$2 star 

506 1# $$a Access restricted to authorized Harvard users. $$f Online access with authorization. $$2 star 

506 1# $$a Digital copy available by consultation with staff. $$f Restrictions unspecified $$2 star 

538 (Systems Details Note)

http://www.loc.gov/marc/holdings/hd538.html 

OCLC Data Sync: The normalization rule deletes existing subfield $5 in the 538 and adds $5 MH to the field in OCLC. The rule does not change anything in the Alma NET holdings.

http://www.loc.gov/marc/holdings/hd583.html 

Use to record the mandatory HUL “committed to preserve” note for 852 $$b NET $$c RDM holdings and recommended for $$b NET $$c GEN holdings digitized for preservation rather than strictly for access.

Use standardized terms from one of the following sources: Preservation & digitization actions: terminology for MARC 21 Field 583 (pda) or Standard terminology for the MARC 21 Actions Note Field (stmanf). 

OCLC Data Sync: The normalization rule deletes existing subfield $5 in the 583 and adds $5 MH to the field in OCLC. The rule does not change anything in the Alma NET holdings.

Use to describe a reproduction of an original item(s).

OCLC Data Sync: Holdings with 843 $a that begins “Electronic” meet the criteria for syncing. The 843 field is converted to fields 533 and 539 and added to the bibliographic record for the electronic reproduction.  The rule does not change anything in the Alma NET holdings.

Alma Analytics -- Physical Items > Holding Details > Local Param 10 

$$a - Type of reproduction (NR): Use “Electronic reproduction”

$$b - Place of reproduction (R) Name of the place where the reproduction was made. Subfield $b is repeatable and should be used to record the place name when more than one agency is responsible for the reproduction.

$$c - Agency responsible for reproduction (R):  Use “Harvard Library Imaging Services” for materials reproduced by Imaging Services. Subfield $c is repeatable and should be used to record other agencies responsible for the reproduction, e.g., NEDCC. The form of name should reflect the use of agency at the time of reproduction.

$$d - Date of reproduction (NR): Use for the year the reproduction was made.

$$f - Series statement of reproduction (R):  Project titles are recorded in the program/project series name in field 843 subfield $f (NET holdings record) and in field 710 (bibliographic record). (See Best Practice for MARC21 Coding of Local Collection Names at Harvard for the use of the 710 field instead of the 830 field.) The subfield $f can also be used to note access copies made on demand or over the counter.

$$m - Dates of publication and/or sequential designation of issues reproduced (R): Sequential designation and/or dates of publication of the original issues that have been reproduced.

$$n - Note about reproduction (R): Note field used to record copy specific notes. Can be used to record library name and call number of copy digitized from the original, any imperfections (e.g., damaged or missing pages), and/or source for the reproduction. 

$$7 - Fixed-length data elements of reproduction: This varies, being the same for all monograph categories (single volumes and complete and incomplete works in parts), but different for serials. Note: Past practice coded character position 14 "s" for electronic. OCLC prefers code "o" for locally digitized remote access resources. There are no current plans to change this character position retrospectively.

Mandatory subfields; use all other subfields at the discretion of the unit

$b - Location: Use NET when the digitized resource is available to current Harvard users and has an actionable link in the 856. For content that is not available Harvard-wide, staff should use their local sublibrary code and collection code "NET.”

$c - Sublocation or collection: Use GEN for locally digitized material, RDM for digital masters, or other project specific sublocation or collection code.  See Alma location codes - usage information

856 (Electronic Location and Access)

https://www.loc.gov/marc/holdings/hd856.html 

Use the 856 field to link directly to locally digitized material, PDS list object, or indirectly to a finding aid with links to locally digitized material. Use a NRS persistent identifier (i.e., URN) in the subfield $u whenever possible.

For finding aids, ArchivesSpace generates permalinks, which can be found in the citation field (ex. https://id.lib.harvard.edu/ead/sch01609/catalog). Older finding aids may also have a link in the NRS persistent identifier form (ex. http://nrs.harvard.edu/urn-3:RAD.SCHL:sch00009).  Either link can be used in the subfield $u.  

OCLC Data Sync: Holdings with 856 subfield $u including one of the following URL patterns, preceded by http:// or https:// meet the criteria for syncing:

$3 - Materials specified (Recommended): Use to identify the specific part or parts of a work or collection made available through the link. Alternatively, use the subfield $3 to indicate that there is digitized material in a collection, e.g., “Digitized items available through finding aid.” 

When applicable the subfield $3 should match with information in field 843 subfield $m. If what has been digitized is too long or complex to be interpreted by a user, then we recommend using natural language. When only one part is digitized, consider ending the statement in field 856 subfield $3 with the word “only.”
