## 1. BACKGROUND

The RDA Toolkit Restructure and Redesign Project (3R) has introduced a new Manifestation level element "type of binding" to the RDA element set. Type of binding is defined as:

"A method used to bind a published or unpublished manifestation."

Information about binding can already be recorded in various parts of the MARC 21 Bibliographic Format. For instance, it can occur in subfield \$q (Qualifying information) after the ISBN in the 020 field (International Standard Book Number). Likewise, it is aligned to field 024 (Other Standard Identifier) subfield \$q and 027 (Standard Technical Report Number) subfield \$q. In these contexts the subfield \$q represents an unstructured qualifier to the relevant standard number. Recording a type of binding can also be done using field 563 (Binding Information) subfield \$a. Again, in this context data may be recorded using an unstructured form of note.

Although it is possible to express a type of binding using an unstructured (i.e. free text) approach in MARC 21, the new RDA also allows this element to be recorded in a variety of other ways. These in turn offer the potential of enhanced functionality in a catalog search and collection management context. For example, recording RDA’s controlled terms for type of binding could be used to provide a more structured means of indexing and faceting binding information for library users. Likewise, these terms could be used to simplify the process of making resource selection, shelving, and preservation decisions at the collection level. In addition, since these controlled terms for type of binding are all associated with corresponding RDA Registry URIs, this element’s vocabulary could also be used to support linked data applications. In order to exploit the full potential offered by the RDA "type of binding" element, this paper recommends that new encoding is specified to carry it in the MARC Bibliographic format.

## 2. DISCUSSION

The new RDA element "type of binding" is associated with its own vocabulary encoding scheme as set out below:

closed ring
hardback
open ring
paperback
spiral

These categories of binding may already be expressed in the MARC Bibliographic format in an unstructured way; however the existing provision is limited in various regards. Hence, although 020, 024 and 027 \$q offer the means to record binding information, this subfield is also used for other purposes; its broad scope is defined as follows:

\$q - Qualifying information
A brief statement of qualifying information concerning the item associated with a number being recorded in subfield \$a or subfield \$z.

The following examples demonstrate a range of applications unrelated to binding:

020 ##\$a9780060723804\$qacid-free paper

020 ##\$a0717941728\$qfolded\$c\$0.45

Indeed, even when binding information is recorded, the notation used is subject to variation as the following examples demonstrate:

020 ##\$a0394170660\$qRandom House\$qpaperback\$c\$4.95

020 ##\$a0835200019\$qpbk.\$c\$2.95

The generalized and uncontrolled nature of 020, 024 and 027 \$q content means that it is ill adapted for supporting more than the most rudimentary search functionality. The alternative means of recording binding information in MARC are also limited. Although field 563 is simply labeled "Binding Information", its definition and scope indicate that its principal usage is constrained:

Field 563 Definition and Scope:
Binding information intended primarily for use with antiquarian materials, rare books and other special collections.
It is not intended for serials bound together after publication for shelving and storage purposes.

Furthermore, like 020, 024 and 027 \$q, the 563 field is designed to carry an unstructured note, rather than controlled term. The following examples demonstrate this:

563 ##\$aLate 16th century blind-tooled centrepiece binding,dark brown calf.\$5StEdNL

563 ##\$aGold-tooled morocco binding by Benjamin West, ca. 1840.\$5Uk

It is also notable that field 563 may be used to record a Uniform Resource Identifier in subfield \$u. However, as the definition of \$u indicates, this is for purposes of referencing an electronic item rather than a vocabulary encoding scheme for a controlled term:

\$u - Uniform Resource Identifier
Uniform Resource Identifier (URI), for example a URL or URN, which provides electronic access data in a standard syntax. This data may be used for automated access to an electronic item using one of the Internet protocols.

In addition, a significant consideration as regards the application of field 563 is that early printed books were often originally sold without any binding attached to them in the first instance. A binding might have been subsequently added by the owner of the item and so different items exemplifying the same manifestation may carry different bindings as a result. Under these circumstances the RDA element "type of binding" would be out of scope because it is expressed as a manifestation attribute; a separate RDA element "binding of item" could be used to express this concept as a relationship instead.

As described above, the existing coding in MARC fields 020, 024, 027 and 563 offers limited, unstructured means to record type of binding information.  In the case of field 020, its application in relation to binding type can also be ambiguous. If, for example, a resource description carries subfield \$q qualifiers for both hardback and paperback binding, then this raises the question of which binding relates to the physical details recorded in field 300 (Physical Description). The dimensions, font size and other physical characteristics of a manifestation may vary according to the binding which accompanies it. Going forward, it would be desirable to express type of binding in an unambiguous way which relates the value recorded to other aspects of physical description expressed in the same bibliographic record.

### Bibliographic Field 340

Field 340 offers the potential to record the type of binding in a more structured and unambiguous way than those fields listed above; it also allows for the recording of URIs. Field 340 (Physical Medium) is already used to express a wide variety of manifestation entity level RDA vocabularies in MARC. These include the vocabularies for production method, generation, layout, font size and polarity. A full list of existing 340 subfields is given below, followed by the field’s definition and scope:

• 340 - Physical Medium (R)
• Indicators
• First - Undefined
• # - Undefined
• Second - Undefined
• # - Undefined
• Subfield Codes
• \$a - Material base and configuration (R)
• \$b - Dimensions (R)
• \$c - Materials applied to surface (R)
• \$d - Information recording technique (R)
• \$e - Support (R)
• \$f - Production rate/ratio (R)
• \$g - Color content (R)
• \$h - Location within medium (R)
• \$i - Technical specifications of medium (R)
• \$j - Generation (R)
• \$k - Layout (R)
• \$m - Book format (R)
• \$n - Font size (R)
• \$o - Polarity (R)
• \$0 - Authority record control number or standard number (R)
• \$1 - Real World Object URI
• \$2 - Source (NR)
• \$3 - Materials specified (NR)
• \$8 - Field link and sequence number (R)

Field Definition and Scope:
Physical description information for an item that requires technical equipment for its use, and/or more granular description information of an item's material properties to facilitate access and discovery or to support collection management.
Coded physical information is contained in field 007 (Physical Description Fixed Field). The field is repeated for each subfield \$3 (Materials specified).

As indicated by its definition and scope, field 340 allows for the description of a resource’s physical attributes in a focused way as a means of supporting discovery, access and management information functions. The inclusion of subfield \$2 (Source) in its list of subfields means that it is optimized for recording terms from a controlled vocabulary. Likewise, the presence of subfields \$0 and \$1 mean that it can also be used to carry URIs associated with those terms.

## 3. PROPOSED CHANGES

It is proposed to add another subfield to Bibliographic field 340 to carry type of binding information. This would be to record a structured description using the RDA vocabulary encoding scheme.

In field 340 of the Bibliographic format, define \$l as follows:

\$l – Type of binding (NR)
A method used to bind a published or unpublished manifestation.

## 4. EXAMPLES

The following examples present two illustrations of type of binding in field 340 \$l. The subfield \$2 code "rdatb" is modelled on the anticipated curie for RDA Registry URIs associated with the vocabulary encoding scheme for type of binding.

For purposes of brevity the examples do not include notes or subject headings. These would offer no additional value in terms of contextual information.

## 5. BIBFRAME DISCUSSION

When the proposed addition is further developed, approved, and implemented, the BIBFRAME ontology may be modified to add a new property.

## 6. QUESTIONS FOR DISCUSSION

6.1. Is the benefit of recording type of binding using a structured description, identifier or URI sufficiently articulated?

6.2. Is field 340 subfield \$l a suitable subfield in which to record a structured description for type of binding?

6.3. Are there any circumstances in which it would be desirable to record more than one value for type of binding in the same description (e.g. an aggregate resource, the components of which represent different binding types).
