B. Marks of omission, i.e. three points ( ... ) indicate the omission of some part of an element (see
0.7.1, 0.7.2).
One punctuation symbol, the plus sign ( + ) preceded and followed by a space, is prescribed punctuation
in area 5 (see 5.4).
C. Parentheses ( ( ) ) are prescribed punctuation to enclose each series statement in area 6, to
enclose certain elements in area 4, and to enclose information within particular elements of areas 1, 5 and
8.
0.4.9 When in an area or an element the same information appears in two or more languages
and/or scripts, the following provisions apply:
When one element is recorded in two or more languages and/or scripts, the information in each language
and/or script after the first is preceded by a space, equals sign, space.
When, in a single area, two or more elements are recorded in two or more languages and/or scripts, the
elements in each language and/or script are given together with the appropriate preceding punctuation for
each element. The whole group of elements for the first language and/or script recorded is preceded by
punctuation appropriate to the first element and each group after the first is preceded by a space, equals
sign, space.
0.4.10 An area or element that does not apply to the publication is not included in the description.
The preceding or enclosing prescribed punctuation of such an area or element is also omitted.
0.4.11 When information is given in scripts written from right to left, commas and semi-colons
used as prescribed punctuation are reversed when that is the style of the script. Similarly, the point, space,
dash, space combination of prescribed punctuation reads from right to left and the meanings of open and
closed parentheses and square brackets are reversed. The diagonal slash and groups of western arabic
numerals which are not reversed in such scripts are not reversed when given.
See Appendix B for the treatment of information given both in scripts written from left to right and in scripts
written from right to left.
The complete Punctuation pattern for each area is set out at the beginning of the area.
0.5 Sources of information
0.5.1 Order of preference of sources
For many kinds of non-book materials the formulation of an adequate bibliographic description is
problematic because of the absence of any title-page or single equivalent source of information. In
describing an item it may therefore be necessary to select from such disparate sources of information as
the item itself (where the data may be given in a visual or auditory form or both), an affixed label, a
container or an enclosure or other accompanying textual matter such as a manual. In deciding an order of
preference among these sources of information the following principles should be observed:
A. Sources permanently associated with the item will normally be preferred to sources having only an
accidental or fugitive connection with it. Thus the title frames of a motion picture, the labels on the two
sides of a sound disc or the central area of a stereograph reel will normally be preferred to the container or
accompanying textual matter found with any of these items.
