What is an ISTC?

Posted by Brian Kelly on March 15th, 2010

ISTC stands for the International Standard Text Code (ISTC). This is a new numbering system developed to enable the unique identification of textual works and is published by the International Standards Organization as ISO 21047.

The ISTC Web site states that: “The International Standard Text Code (ISTC) system is a global identification system for textual works. It is primarily intended for use by publishers, bibliographic services, retailers, libraries and rights management agencies.” and “An ISTC can be applied to any textual work by any authorized representative of the author of a textual work”.

So whereas the ISBN distinguished between hardback and paperback versions of a text, the ISTC works to bring together a group of resources with the same content.

Crucially, “an ISTC does not ‘belong’ to a single author/publisher” – it belongs to the work. Put simply, that means that when the next Terry Pratchett novel comes out in hardback, the publisher can apply for an ISTC for it. The same ISTC is then also used for example, for paperback and large-print versions published in the UK even if they are published by different publisher(s) and for any versions published elsewhere.

So it could be a useful bit of data to include in library catalogue records, making it easier to search for a specific text work, for example, where a public library has multiple copies of the work in a number of branches, some in hardback (with its ISBN) and some in paperback (again with its own ISBN).

If you are a cataloguer, you might like to take a look at MARBI Discussion Paper 2010-DP03 which looks at the detail of where to place the ISTC within MARC 21 bibliographic and authority records.

Perhaps you’ve not seen an ISTC yet, but I gather around 4,000 have been assigned already. Initially they’ll be turning up in book trade records; then I’d expect to see them in bibliographic data suppliers records, and finally in public (and other) library catalogues. So keep a watch out for them.
