International Standard Text Code
The International Standard Text Code ( ISTC ) is a coding system similar to the ISBN that was developed by the ISO . It has been published as ISO 21047: 2009 since March 2009.
purpose
Primarily published texts such as books should be marked . While with the ISBN, each edition of this text is given its own ISBN by a publisher ( Schiller's robbers were registered with dozens of ISBNs), a text (in a translation) also receives exactly one ISTC. This then also applies to different media, e.g. in printed form, as an audio book , e-book or digitized version .
Various media and editions can be found for a work via the ISTC; In the case of a translation, reference can be made to the ISTC of the original and for compilations (thus including titles) the ISTC of the texts contained can be given.
format
An ISTC consists of 16 (Arabic) digits 0 - 9 together with the letters A - F , so it is a hexadecimal number .
The coding is divided into four parts:
| field | length | Put | meaning |
|---|---|---|---|
| Registration | 3 | 1-3 | Internal purposes (registration authority) |
| year | 4th | 4-7 | Year of registration, not text creation or publication |
| plant | 8th | 8-15 | Allocated registration number |
| Check digit | 1 | 16 | MOD 16-3 according to ISO / IEC 7064 |
Examples:
- ISTC 0A9 2002 12B4A105 7
- ISTC 0A9-2002-12B4A105-7
