Cataloging CD-ROMs and Computer DisksCD-ROMs and computer disks are cataloged according to their content. The cataloger should determine if the item is a monograph, serial, database or software program and catalog it in the books (bks), serial (ser) or computer file (mdf) format as appropriate. Be sure to search all files for copy for the item. If copy is only available in a file which the cataloger will not be using, use the "TRA DER" or "TRA CRE*" transfer commands to move the copy to the chosen file. For help in determining the correct file, see Content Versus Carrier (Electronic Resources) Definition CD-ROM is short for compact-disc read-only memory. The disc is used for the permanent storage of data or audio or video recordings. This document covers discs (or disks in the case of computer disks) that contain data. Disc or disk Disc is the word used to indicate optical storage devices (CD-ROMs and compact discs). On older records the word "disk" will appear. Disk now refers to other computer contexts, such as floppy disk, hard disk, etc. Chief source of information The chief source for cataloging CD-ROMs and computer disks is the title screen. Several alternate chief sources are listed in revised Chapter 9 of AACR2. In practice we will most often be cataloging from the CD-ROM or computer disk label. Always, make a note in the catalog record showing what was chosen as the chief source, e.g., Title from title screen or Title from label on disc. Fixed fieldsFor assistance with fixed fields and values see: LC's MARC documentation. Refer also to Princeton Policy in the MARC format section of the documentation in regard to the use of 006 and 007 fields. Variable fieldsAttention should be paid to the following fields (some of which are unique to computer files). Other fields are used in the usual manner where appropriate. 130 (uniform title) For serials: Provide a uniform title as usual if the title conflicts with an unrelated serial publication. In addition, if the print title and its CD-ROM (or computer disk) counterpart have the same title, provide a uniform title indicating the specific computer file format using a qualifier such as (CD-ROM) or (Computer disk). 24x (titles) General material designator (GMD) for CD-ROMs and computer disks is h[electronic resource] The 245 title is taken from the chief source as indicated above. Title variations often appear in accompanying material, etc. These should be added as a 246 field. 250 (edition) The term "version" is often used to distinguish between alternate computer file formats. If the term "CD version" appears, include this in the 250 field. 256 (file characteristics: MDF ONLY) Usually Computer data for CD-ROMs. 260 (imprint) Many computer file titles are issued by a commercial publisher who may have nothing to do with the original print version, e.g.: SilverPlatter Information. In general these publishers are not traced. Non commercial bodies associated with the intellectual content of the title are traced as usual. 300 (physical description area) The physical unit for the CD-ROM is computer optical discs The c is always 4 3/4 in. The physical unit for computer disks is computer disks. The c is always 3 1/2 in. The small guide, which is often enclosed within the jewel case, can be described here, e.g., +e guide (15 p. ; 12 cm.) Other larger manuals, installation discs, etc. are usually described in a note. 362 (designation : SERIALS ONLY) Often is an unformatted note with information from accompanying material, e.g., Began with Mar. 1991. 1980-1989 issued on one retrospective disc; 1990, 1991 issued on annual discs. The "earliest" issue may be difficult to determine where discs are cumulative. It is often necessary to use the 'Description based on' note. 500 (notes) Accompanying material: Describe in a 500 field the manuals, guides and
installation discs, etc. which are either too numerous or complicated
to describe in the 300 field. Accompanied by installation and retrieval
software on two 5 1/4 in. disks and reference manual. 515 (numbering irregularities: SERIALS ONLY) Often used to describe the date of coverage and cumulation patterns: Backfile covers 1973-1983; current discs are cumulative and cover 1984 through the current quarter. 530 (additional physical form note) CD-ROMs often have titles that vary from their print counterparts. An
attempt should be made in these cases to add a note and added entry for
the title of the print version. Use a 530 note and add a 776 field. If the CD-ROM includes more than one title, the note/tracing described above should also be applied. 530 CD-ROM ed. of: American statistics index; Statistical reference index;
and: Index to international statistics. 776 1 tAmerican statistics
index 538 (system requirements) Contains system information about the equipment needed to run the CD-ROM. Use this information if included with the item and readily available: System requirements: IBM PC or compatible; 4 MB RAM; MS-DOS 3.1 or higher; CD- ROM drive. 6xx (subject headings) If the item is available in another format use the same subject headings if still valid. Some Guidelines for Computer File Related Subject Subdivisions Databases [Form subdivision] Software (H2070) [Form subdivision] Computer programs (H 2070) Use under topical headings for works on computer programs, whether or not lists of machine instructions are included. 753 (technical details) This is a searchable field that provides information about system requirements noted in the 538 field. We no longer use this field, but it may appear on older records. 780/785 (Continues:/Continued by: SERIALS ONLY) If a CD ROM changes title, add appropriate continued by notes to the
old title and treat the title change as a new title as per normal serial
cataloging procedures. References See CONSER Cataloging Manual, module 30 for more detailed information and examples. Local informationCall number CD-ROMs should be given accession numbers. Make a permanent card for the shelflist and use the next available number for the particular location. Catalogers should go up to the shelflist and do this themselves. The accession number should appear in the 852 field on the holdings screen
as: COMPUTER FILE 12 LocationCD-ROMs are only to be placed in locations that have the appropriate
computer equipment. This includes most branch libraries and the various
reference locations. CD-ROMs and computer disks should never be assigned
to Firestone stacks, except in the case of accompanying material. HoldingsNo holdings data for serials are maintained in Technical Services for CD-ROM and computer disk titles. Add the following 866 note to the holdings record for all CD-ROMs and computer disks that are cumulative, i.e. for which each issue supersedes previous versions : 866 _0 a FOR HOLDINGS CONSULT ( ) LIBRARY For true serials, the same note is added, except for FilmB. For FilmB titles add the issues being cataloged. Subsequent holdings will be maintained by FilmB. Other locations have the option of requesting that holdings be added after new issues are received. Exception: For CD-ROM's installed on a tower, DO NOT add any note or holdings. No holdings are included for these titles. Post catalogingBarcodes are not assigned or affixed to CD-ROMs and their associated documentation. For information on marking the item see: Physical Treatment and Marking of CD-ROMs, Sound Discs, Computer Disks. Make a printout of the OPAC record and mail it with the CD-ROMs and accompanying material to the appropriate location. |
