Hi Jay: In general, E-books that maintain the pagination of the original are treated as reproductions, and require the following fields:

Fixed Field:

• Type: a
• Blvl: m
• Form: s

Note: all other fields coded as in the original print publication, including dates and Ctry.

Typical coding of Control Fields:

• 006 T006: m File: d (other codes as appropriate)
• 007 c $b r $d c $e n
• 020 Should contain only the ISBN of the e-book, not the original. You may provide the ISBN of the original in a 776 field. Example:
  • 020 0585325634 (electronic bk.) : $c $20.95

Variable fields:

• All descriptive fields coded as in the original, including 260 (edition of original) and 300 (pagination of original).
• The 245 should be identical to the original, except you must add $h [electronic resource] after the title proper

Treatment of Fields specific to e-book reproductions:

• Omit 256 Electronic file characteristics. Comment: Only required if item is coded in the primary fixed field as e-resources (type: m, blvl: m).
• 516 Type of computer file -- Generally omitted (LCRI 1.11A " Transcribe the bibliographic data appropriate to the original work being reproduced in the following areas: title and statement of responsibility; edition; material (or type of publication) specific details; publication, distribution, etc.; physical description; series.")
• 538 System requirements - Omit
• 538 Mode of access - Omit because it will be supplied in 533 $n
• 500 Source of title - Omit
• 530 Also available in print - Omit (again, the 533 will cover this).

Note: These fields are required only when cataloging e-resources that are not reproductions. For reproductions, the 533 field is required.

• 533 with details of the e-book publishing. Here's a typical netLibrary example:
  • 533 Electronic reproduction. $b Boulder, Colo. : $c NetLibrary, $d 2000. $n Available via World Wide Web. $n Access may be limited to NetLibrary affiliated libraries.

Also add:

•  Optional local genre/form heading, example: 655 7 Electronic books. $ 2 local
• Corporate author added entry, example: 710 2 NetLibrary, Inc.
• Additional physical form entry (which allows access via the print ISBN), example: 776 1 $ c Original $ z 0664256716 $ w (DLC) 99026278 $ w (OCoLC)41086743

Note: The presence of the 533 provides the justification for the 710 and the 776 fields.

And, of course:

• Electronic location/access, example: 856 4 $3 Bibliographic record display
  $u http://www.netLibrary.com/urlapi.asp?action=summary&v=1&bookid=41201 $z An electronic book accessible through the World Wide Web; click for information

Hope this helps!

PS E-books that don't carry the same pagination as the original are generally not treated as reproductions. Instead, they follow the rules for a monographic e-resource, in which most of the fields you listed as required are included, and there is no 533. The fixed field generally reflects the e-resource and not any print equivalent.

Subject: [OCLC-CAT] Electronic reproductions: which fields are required?

I have been given a pile of e-books to catalogue and am becoming muddled with trying to follow the LC/OCLC standards of doing them in a similar manner to microforms, i.e. describing the characteristics of the  electronic version in a 533 note.

What do I do with certain MARC fields that are either required or useful  when cataloguing an electronic resource? I refer to:

256 Electronic file characteristics [required]

516 Type of computer file

538 System requirements [required]

538 Mode of access [required]

500 Source of title [required]

530 Also available in print.

I have seen examples of a Mode of Access: note being put in the 533 $n. Is  this the general practice? Which, if any, should I also put in the 533 $n?

Which, if any, should I put in the normal place? Which, if any, should I just leave out?
