If an e-book has a stable, universally valid access address in the form of a URL (to a publisher or distribution platform), this should be included as a separate element within the metadata record.
Please note, however:
If a Digital Object Identifier (DOI) has been assigned for an e-book, it will be supplied as an identifier for the product in other elements of the metadata record (see Product numbers).
If individually customized URLs are assigned for an e-book depending on the licensing institution, it is advisable to agree about the delivery of such URLs in advance with the responsible library network head office or the responsible service provider for metadata processing.
URL - mandatory, if available |
|||
| Definition | A Uniform Resource Locator (URL) identifies and locates a resource, such as a web page, by the access method to be used and the location of the resource on computer networks. URLs are a subtype of the general identification designation using Uniform Resource Identifiers (URIs). Because URLs are the first and most common type of URI, the terms are often used interchangeably. In common usage, URLs are also referred to as Internet addresses or web addresses. | ||

General notes |
Resolver URLs for persistent identifiers (URN, DOI) may also be supplied in this element. | ||
