1.   General.  Indicate that data are temporary or uncertain by enclosing them within angle brackets ( < > ).  Such data display in all cases.  Treat angle brackets as regular characters, applying normal spacing conventions preceding and following them as illustrated in the examples.

When a date is enclosed within angle brackets, do not use spacing to show that it is an open one:  "<1981->"  When an open date occurs outside angle brackets, use normal spacing preceding or following a hyphen unless preceded or followed by a temporary date enclosed within angle brackets, e.g., "1979-<1980>" or "<1979>-1980."

When spans of beginning and/or ending dates or numbers include temporary data, give the hyphen within or outside the angle brackets as shown in the following examples:

<1966->

<-no. 47>

<May 2001-v. 3, no. 2>

1998-<fall 2001>

<Bd. 4>-Bd. 12

When holdings are enclosed within angle brackets, do not use spacing to show that they are temporary.

b.   Publication, distribution, etc. area ( 260 ).  These conventions do not apply to serials or integrating resources (temporary data not recorded in this field).

Permanent date.  If an entire date is judged to be permanent, record it without angle brackets.

, 1980-

not       <1980-> or , 1980-< >

(v. <1>; v. 1 published in 1980)

Temporary date.  If a portion of a date is temporary, enclose the portion in angle brackets.

, 1980-<1981>

(v. <1-2>; v. 2. published in 1981)

, <1981->

(v. <2>; v. 1-2 published in 1981; LC has only v. 2)

, <1979>-1981.

(v. <2-3>; 3 v. set; LC does not have v. 1)

, <c1978-c1980>

(v. <2-3>; 5 v. set; LC does not have v. 1 or v. 5)

Non-Christian era date.  When the expression of date includes one from the non-Christian era and that date is temporary (as when cataloging a multipart item from other than volume 1), consider the whole expression of date as temporary and give the whole in angle brackets, e.g.,

<Shōwa 57- [1982->

c.   Physical description area ( 300 ).  These conventions do not apply to serials or integrating resources (temporary data not recorded in this field).

General.  Holdings are recorded in holdings and item records.  In general, record holdings for incomplete ("open entry") multipart items in the bibliographic record as well.

Bibliographic record.  Record holdings in angle brackets following the specific material designation until the item is complete and the record is closed.

1)   When a single piece of a multipart item is held, record only the piece/number designation.

v. <1> :

sheets <3> :

sound discs <2> :

film cassettes <B> :

maps <4> :

2)   When more than one piece of a multipart item is held, indicate the piece numbers/designations held inclusively, if they are consecutive, or individually if they are not consecutive.

v. <1-2> :

film cassettes <3, 5> :

microfilm reels <4, 6, 7-10> :

microscope slides <A-C, E> :

1 atlas (v. <1> ; maps (some col.) ; 43 cm.) + <1> texts (30 cm.)

3)   For multipart items in which the number of bibliographic units differs from the number of physical units (as originally issued in contrast to subsequent binding (cf. LCRI 2.5B18)), formulate an intelligible statement of the situation as follows:

a)   Record the numbers/designations of the bibliographic units held followed by a semicolon, the word "in" and the number of physical units; enclose the entire statement within angle brackets following the specific material designation.

v. <v. 1-2; in 3> :

b)   In complicated situations it is necessary to judge the best formulation on a case-by-case basis.  In general, when bibliographic units are themselves further divided into parts, etc., indicate this by using the numbers/designations applicable to each unit, separating this information by semicolons.

v. <v. 1, pt. 1; v. 2; in 3> :

The formulation given in the physical description area may depend upon whether a contents note is given, and if so, the information included there.  For example, if all parts of a volume are held and are recorded in the notes area, it is not necessary to itemize them in the extent of item statement as well.

v. <v. 1, pts. A-B; v. 2, pts. A-B; v. 3, pts. A-B; v. 4, pts. A-B; v. 5-14; in 18> :

(No contents note given)

v. <v. 1; v. 2, pts. A-B; in 3> :

505 1# $aNo. 1, pt. 1. Inorganic ligands / compiled by Lars Gunnar Sillén. Pt. 2. Organic including macromolecule ligands / compiled by Arthur E. Martell -- [No. 2.] Pt. A. Inorganic ligands / compiled by Erik Högfeldt. Pt. B. Organic ligands / compiled by Douglas D. Perrin (2 v.)

v. <v. 1, pt. 1; v. 2; in 3>

505 1# $av. 1. Introduction <pt. 1> - v. 2. Guide (2. v.).

4)   For multipart items in which the number of pieces is very large or the pieces have no individual numbering/designations, give in angle brackets the cumulative number of pieces held.  If the set is incomplete, give the number preceding the specific material designation.

(Serial)

e.   Series area:  open entry multipart items in series ( 4XX ).  When a multipart item itself is in a series and the multipart item is classified as a collection, record the numbering of the series in the collected set record according to the following guidelines until the multipart item is complete.

1)   Record the series numbering for the first or last volume as permanent data, i.e., not within angle brackets.

2)   Record all the series numbering as permanent data when the first or last volume is in hand with other consecutive volumes of the multipart item and the series numbering is scattered.

3)   In all other situations, record the series numbering as temporary data, i.e., within angle brackets.

Use a hyphen to separate consecutive numbers and a comma to separate scattered numbers.  When the multipart item is complete, show all numbering as permanent data.

First or last volume of multipart item being cataloged

 no other volumes:

245   $aMultipart item title

300   $av. <1>

4XX   $a________ ;$vv. 13

(v. 1 of multipart item is v. 13 of series)

245   $aMultipart item title

300   $av. <5>

4XX   $a________ ;$vno. 22

(v. 5 of multipart item is no. 22 of series)

 other volumes and series numbering consecutive:

245   $aMultipart item title

300   $av. <1-2>

4XX   $a________ ;$vno. 3-<4>

(v. 1-2 of multipart item are no. 3-4 of series)

 other volumes and series numbering scattered:

245   $aMultipart item title

300   $av. <1-3>

4XX   $a________ ;$vv. 5, 7, 10

(v. 1-3 of multipart item are v. 5, 7, 10 of series)

245   $aMultipart item title

300   $av. <1, 3>

4XX   $a________ ;$vno. 24, <30>

(v. 1, 3 of multipart item are no. 24, 30 of series)

Volumes other than first or last volume of multipart item being cataloged

 only one volume in hand:

245   $aMultipart item title

300   $av. <2>

4XX   $a________ ;$vno. <18>

(v. 2 of multipart item is no. 18 of series)

 more than one volume in hand and series numbering consecutive:

245   $aMultipart item title

300   $av. <2-4>

4XX   $a________ ;$vno. <9-11>

(v. 2-4 of multipart item are no. 9-11 of series)

 more than one volume in hand and series numbering scattered:

245   $aMultipart item title

300   $av. <2, 4>

4XX   $a________ ;$vno. <31, 42>

(v. 2, 4 of multipart item are no. 31, 42 of series)

Change from previous practice:  PCC practice:  Note that it is no longer necessary to create an 8XX added entry solely because the numbering is not consecutive or the first number is not permanent.  It is not necessary to change existing records that reflect the old practice until the record is closed.  If it is necessary to create an 8XX added entry for some other reason, give the numbering in the same manner as for 4XX fields.

f.   Series area:  only some issues of a serial or parts of a multipart item in a series ( 4XX ).  If some issues of a serial or parts of a multipart item are in a series and others are not, precede the series title with an indication of the particular issues or parts to which the series applies.  Separate the indication from the series title with a colon-space.

500 ## $aVols. 1-6 prepared by H. Lepage; v. 7-<8> by E. Duvernoy.

Do not use "empty" angle brackets; instead, insert one space after or before a hyphen if additional information is expected.

500 ## $aVol. 9- edited by G. Svehla has title ...

500 ## $aVols. -10 translated by ...

Contents notes.  If volume one is not held, begin the field with two adjacent hyphens followed by a space and the number of the first volume actually held.

300 ## $a<v. 2, pt. 1-2; in 3>

505 1# $a-- v. 2. La foto-restituzione grafico-numerica. pt. 1. Generalita (2 v.). pt. 2. Fotographie oblique <v. 1>

If the set is incomplete but volume one is held, put the space-dash-space before each title (other than for volume one) that is being recorded and leave four spaces for the missing volume(s).

When the number of bibliographic units differs from the number of physical units and the parts of each bibliographic unit are indicated in the contents note, record the numbers/designations of the parts that are incomplete in angle brackets.  In general, include in the angle brackets any designation of the part, especially if this varies from the designation of the larger unit of which it is a part.

300 ## $a<pt. 1; pt. 2, v. 1; in 3>
