isbn

The isbn package inspects and verifies International Standard Book Numbers (ISBNs) according to the ISO standard.

[!WARNING] This package will in its current version validate British Standard Book Numbers (SBN), ISBN-10 and ISBN-13 only according to their structure.

As of now it will not validate if an ISBN is actually contained in an ISBN range.

Furthermore it will not handle other but similar identifiers like EAN-13 in general, Digital Object Identifier (DOI), ISBN-A, International Standard Music Number (ISMN), International Standard Serial Number (ISSN) or International Standard Link Identifier (ISLI).
