Yale policy is to create volume holdings for multipart monographs even if holdings are complete at the time of cataloging. ANSI Level 4 is used:
"Level 4 provides detailed extent of holdings information. The detailed holdings statement may be either itemized or compressed; the detailed holdings statement may be either open or closed. ... If enumeration [is] applicable, the most specific levels (including all hierarchical levels) must be included."* For Yale policy on itemization vs. compression, see Section 4. below. Yale policy for multiparts is that holdings are never left open.
HISTORICAL NOTE: ANSI Level 1 ("no indication of extent of holdings") was used for microform reproductions of complete multipart works and some recon titles. CURRENT PRACTICE: Holdings for single basic bibliographic units (e.g. a single volume monograph) are not recorded. If a single basic bibliographic unit has an accompanying secondary bibliographic unit, holdings are generally not created.
ANSI Level 2 ("general guidance as to the extent of the institutions' holdings") and Level 3 ("summary extent of holdings") are not used.
* Yale holdings are recorded at mixed levels, generally using summary extent when all parts within a range are held, and detailed holdings when parts are incomplete. For workflow purposes, all holdings statements are coded at Level 4. For detailed scope notes on Levels 1-4, see ANSI p. 15.
"When the extent of holdings is explicitly recorded, this standard requires the recording of those pieces held rather than of those pieces not held." (ANSI p. 2, 1.2.4. Pieces Held) See also ANSI p. 26: "Record and display data in a positive sense; that is, emphasize that which is held rather than that which is not."
Use prescribed punctuation when recording holdings.
