Field definition and scope
This field contains the information required to locate an item. The information may simply identify the organization holding the item or from which it is available, or it may also contain detailed information to locate the item in a collection. Several subfields duplicate those in the 863-865 Enumeration and Chronology fields. They are used in field 852 when there is no 863-868 field in the holdings information, for example, for holdings for single-part items or for multipart and serial items reported at Holdings level 2 (Leader/17, Encoding level, code 2).
OCLC local holdings records are separate holdings records linked to a related OCLC bibliographic record. They report holdings information for a single copy of an item. A single 852 location field and any associated holdings fields are used.
Guidelines for applying content designations
First Indicator - Shelving scheme
The first indicator position contains a value that indicates the scheme used to shelve a bibliographic item in the collections of the reporting organization.
- No information provided
Value indicates that shelving scheme information is not provided.
0 - Library of Congress classification
Value 0 indicates that the item is shelved by a Library of Congress classification number. Use ‡h to indicate this number. The source of this number is either the Library of Congress Classification schedules or LC Classification-Additions and Changes.
1 - Dewey Decimal classification
Value 1 indicates that the item is shelved by a Dewey Decimal classification number. This number, which is contained in subfield $h (Classification part), is assigned from the Dewey Decimal Classification, accessed through electronic or printed versions. A full description of a Dewey Decimal classification number is given under field 082 (Dewey Decimal Call Number) in the MARC 21 Format for Bibliographic Data.
2 - National Library of Medicine classification
Value 2 indicates that the item is shelved by a U.S. National Library of Medicine classification number. Use ‡h to indicate this number. The source of this number is the National Library of Medicine Classification schedules QS-QZ and W or from the Library of Congress Classification schedules used by the National Library of Medicine.
3 - Superintendent of Documents classification
Value 3 indicates that the item is shelved by a U.S. Superintendent of Documents classification number. Use ‡h to indicate this number. The source of this number is the U.S. Government Publishing Office's Superintendent of Documents Classification System.
4 - Shelving control number
Value 4 indicates that the item is shelved by a shelving control number, which is contained in subfield ‡j (Shelving control number).
5 - Title
Value 5 indicates that the item is shelved by a title. If necessary, this title is contained in subfield ‡l (Shelving form of title).
6 - Shelved separately
Value 6 indicates that parts of the item are shelved separately because they are classed separately.
7 - Source specified in subfield ‡2
Value 7 indicates that the item is shelved by a classification number in a scheme other than that specified by one of the other defined values and for which an identifying code is given in subfield ‡2. The codes to be used are given in Classification Scheme Source Codes.
8 - Other scheme
Value 8 indicates that the particular shelving scheme is known but is not specified.
Second Indicator - Shelving order
The second indicator position contains a value that indicates whether a serial or multipart item is shelved under a primary or an alternative numbering scheme. The distinction is necessary when an item carries two numbering schemes. The numbering scheme may be an alphabetical, numerical, or chronological designation.
- No information provided
Value indicates that the shelving order is not provided.
0 - Not enumeration
Value 0 indicates that the item is not shelved by enumeration.
1 - Primary enumeration
Value 1 indicates that the item is shelved by its primary enumeration. This value is also used when the item has only one numbering scheme.
852 0 2 TRN ‡b TRNG ‡h LB201 ‡i .M63
853 1 0 ‡8 1 ‡a no. ‡i (year)
863 4 0 ‡8 1.1 ‡a 1-343 ‡i 1970-1971
[The items in a series are shelved by the series numbering, 1-343.]
2 - Alternative enumeration
Value 2 indicates that the item carries two numbering schemes and is shelved by the secondary scheme.
852 0 2 TRN ‡b TRNG ‡h LB201 ‡i .M63
853 1 0 ‡8 1 ‡a (year) ‡g no.
863 4 0 ‡8 1.1 ‡a 1970 ‡g 97
863 4 0 ‡8 1.2 ‡a 1971 ‡g 125
[An annual report carries both its year designation (the primary numbering scheme) and the numbering of the series of which it is a part (the alternative numbering scheme). It is shelved by the series numbering.]
‡a - Location
Subfield ‡a identifies the institution or person holding the item or from which access is given. Your OCLC institution symbol is system-supplied in 852 ‡a. This subfield cannot be changed.
If the bibliographic item is owned by an individual or organization other than the one identified in subfield ‡a, the actual owner may be identified in subfield ‡x (Nonpublic note) or ‡z (Public note) or in field 561 (Provenance Note). If the item is physically located somewhere other than the location from which it is available, the physical location may also be identified in subfield ‡x or ‡z of field 852.
‡b - Sublocation or collection
The default holding library code for the OCLC institution identified in 852 subfield ‡a is system-supplied in 852 subfield ‡b. A holding library code is a unique four-character code that identifies a specific department, library, collection, etc., within an institution. You may change the default holding library code to another of your valid holding library codes. 852 subfield ‡b is not repeatable in OCLC systems.
852 DLC ‡b DLCC ‡t 1
‡c - Shelving location
Subfield ‡c contains a description of the shelving location of the item within the collection of the holding organization. It may be used to indicate the physical location within a sublocation; for example, reference alcove, oversize shelving. The description of the shelving location is given in full or in a standardized abbreviated or coded form. 852 subfield ‡c is not repeatable in OCLC systems.

‡f - Coded location qualifier
Subfield ‡f contains a three-character code that identifies the specific issues of the item that are housed in a location different from that of the main holdings of the same item. The three-character code is composed of Qualifier type, Number of units, and Unit type codes. If the location qualifier cannot be expressed in coded form, it may be described in subfield ‡g (Non-coded location qualifier).
The Qualifier type and Unit type codes in subfield ‡f are input in lowercase.
01 Qualifier type
A one-character alphabetic code indicates if it is the latest or previous time or part unit that is housed in a different location.
l - Latest
Code l indicates that the latest, including the current, time or part unit is housed in a different location.
p - Previous
Code p indicates that the previous, not including the current, time or part unit is housed in a different location.
02 Number of units
A one-character number (1-9) specifies the number of time or part units that are housed in a different location. When a number is not required to identify the specific units, the number of units may be omitted. If the number of time or parts units exceeds 9, the location qualifier information may be contained in subfield ‡g (Non-coded location qualifier).
When Qualifier type is Latest (code l), the number includes the current time or part unit. When Qualifier type is Previous (code p), the number does not include the current time or part unit.
1-9 - Number of units
03 Unit type
A one-character alphabetic code describes either the time period or the part that is housed in a different location.
m - Month(s)
w - Week(s)

‡s - Copyright article-fee code
Subfield ‡s contains a copyright article-fee code. A description of the copyright article-fee code is given in field 018 (Copyright Article-Fee Code) in OCLC Bibliographic Formats and Standards.
‡t - Copy number
Subfield ‡t contains a copy number for your local holdings records to distinguish one copy of an item from another, not the number of copies held. The number of copies held is contained in field 008/17-19 (Number of copies reported).
‡u - Uniform Resource Identifier
Subfield ‡u contains the Uniform Resource Identifier (URI), for example a URL or URN, which provides electronic access data in a standard syntax. This data can be used for automated access to an electronic item using one of the Internet protocols. The URI links to the repository that holds the item (regardless of whether the item is analog or digital). This information may also be recorded as an organization code or text in subfield ‡a (Location) and (if applicable) subfield ‡b (Sublocation).
Substituting hexadecimal notation for diacritics and special characters in Uniform Resource Identifiers. When recording a URI in subfield ‡u, you may enter most of the spacing characters listed below as either characters or their hexadecimal equivalents. Consult the table below.
Do not confuse the spacing characters listed below with their long-valid non-spacing counterparts. Use of the spacing characters will be limited almost exclusively to URLs.
1Because the Spacing Underscore may cause problems with MARC output, users may prefer to continue entering it with the hexadecimal value %5F.

A public note that applies to a specific part of the holdings is contained in subfield ‡z (Public note) of the 863-865 Enumeration and Chronology field relating to the part.
‡2 - Source of classification or shelving scheme
Subfield ‡2 contains a MARC code that identifies the source from which the classification or shelving was assigned. It is used only when the first indicator position contains value 7 (Source specified in subfield ‡2). The source of the MARC code is Classification Scheme Source Codes which is maintained by the Library of Congress.

‡3 - Materials specified
When separate local holdings records exist for each part of a bibliographic item and there are no 863-865 Enumeration and Chronology fields used, the 852 field in each record may contain a subfield ‡3 to specify the part of the bibliographic item to which the local holdings record applies.
‡6 - Linkage
See Control Subfields for a description of subfield ‡6.
‡8 - Sequence number
Subfield ‡8 contains data that sequences related holdings records. The sequence number is a variable- length whole number which controls the display and processing sequencing of multiple related holdings records that contain identical 852 ‡a, ‡b, and ‡t.
Local systems may add decimal numbers if desired for insertions in an existing sequence. This subfield does not order fields within a record, but locations in separate holdings records.
