TS 2733

TS 2733 is a documentation standard for the format used to interchange bibliographic information on magnetic tape, providing a common structure for transferring records between data processing systems. Its focus is the exchange packaging and arrangement of bibliographic data; it does not define the actual content of records or the meanings of indicators, identifiers, and field subfields.

Separating record structure from bibliographic meaning

In general technical terms, bibliographic interchange formats make catalog records machine-readable and transferable in a consistent way. In such systems, the format defines how fields are organized, bounded, and transmitted, while the content rules explain how elements such as author, title, and publication data should be interpreted. The key distinction in TS 2733 is that it addresses the interchange structure, leaving field semantics to other rules.

What magnetic-tape interchange meant in practice

Magnetic tape was once a common sequential storage medium for moving large data sets. In that environment, it was important that records be presented in a recognizable order with clear boundaries and a format that different systems could process reliably. This standard provides that shared transport structure for bibliographic records exchanged between data processing systems, supporting interoperability in cataloguing and information exchange workflows. This TSE listing is equivalent to ISO 2709:1977 and reflects the historical foundation of bibliographic information exchange formats.
