Знайшовши на Internet нові для мене документи з UNIMARC, я деякий час перебувала у нерішучості: чи спробувати сповіщати інші бібліотеки.
Можливо, що ці матеріали у Вас вже добре відомі. Тоді вибачайте за те, що потурбувала. Цікаво, що у списку користувачів Unimarc бібліотеки з України не фігурують.

1 INTRODUCTION
The following Guideline shows how the UNIMARC format is to be used when creating
records for electronic resources. This Guideline was developed under the auspices of the IFLA
Universal Bibliographic Control and International MARC (UBCIM) Programme. It results
from meetings of the IFLA Permanent UNIMARC Committee and the requirements of the
International Standard Bibliographic Description for Electronic Resources, ISBD(ER). At
these meetings data elements used to describe electronic resources were compiled and their
location in UNIMARC was determined.
Besides additional fields or content designators redefinition of existing fields may prove
necessary in the future. As a result of the publication of ISBD(ER) certain changes were made
to the UNIMARC Manual. Owing to the increasing use of UNIMARC for electronic
resources and other non-book material and media, requirements for yet additional data may
be encountered. They should be brought to the attention of the IFLA UBCIM Programme
Office.
Section 2 of the Guideline indicates the general model for encoding UNIMARC records for
electronic resources. The following section lists data elements commonly included in
bibliographic descriptions of electronic resources and indicates where each data element
would be placed in a UNIMARC record. Section 4 gives examples of full records for
electronic resources.
This version of the Guideline takes account of the expansion of field 135, details of which were
published in the UNIMARC Manual Update 3. The new values (from character position 2
onwards) are also described in MARC 21 Bibliographic field 007 for computer files on
