|c Dimensions

|f Type of unit
|g Size of unit
|3 Materials specified

Instructions:
Subfield |a is required. Subfield |f is optional. Subfield |3 specifies materials when multiple 300 fields are used. Other subfields are not used for collections, but may be used for cataloging single items. Subfield |c is required for single items.
The 245 and 300 fields should match, both describing either a collection or a single item.

Extent (|a)

Always use subfield |a, and include at least the number of linear feet. Rounding of numbers and extent of decimal points are determined by local practice. If only subfield |a is used, also include the term "linear feet," the number of boxes, and, optionally, the number of other storage formats. Do not abbreviate words.

To calculate footage based on size and number of boxes, use local procedures, or use a linear footage calculator.

Examples:
300 b/b/ |a 10.50 linear feet
300 b/b/ |a 10.5 linear feet (5 boxes)

300 b/b/ |a 10 linear feet (5 boxes) + 2 broadside folders.
Broadsides are not included in the linear footage.

300 b/b/ |a 49.6 linear feet (52 boxes, 12 rolled maps, 74 broadside folders)
Rolled maps and broadsides are extensive, and are therefore included in linear footage.

Type of unit (|f)

Optionally, use subfield |f, following subfield |a. If both subfields |a and |f are used, only the number of linear feet is included in |a; the term "linear feet," and, optionally, the number of boxes of other storage formats, are included in |f.

Examples:
300 b/b/ |a 3.75 |f linear feet (10 boxes)
300 b/b/ |a 0.21 |f linear feet (1 box) + 1 portfolio.

Subfields:
|a Organization
|b Arrangement
|3 Materials specified

Instructions:

Organization (|a)

Use to list series in a collection. Wording is determined by local practice. Separate series by periods. If a collection is arranged in series, use only subfield |a; do not use subfield |b.

Examples:
351 b/b/ |a Organized into three series: I. Writings, 1915-1961. II. Correspondence, 1910-1954. III. Personal Papers, 1900-1957.

Arrangement (|b)

Use to indicate alphabetical, chronological, or other arrangement for a small collection not organized into series.

Examples:
245 10 |a Jane Doe correspondence.
351 b/b/ |b Arranged chronologically.

Materials specified (|3)

Use to indicate a specific part of collection described in this field. Do not use punctuation between |3 and |b, so that these will display as one sentence in the OPAC.

Examples:
245 10 |a Jane Doe correspondence and drawings.
351 b/b/ |3 Correspondence |b arranged chronologically
