A new option for NBAs wishing to disseminate national bibliographic information has been the creation of free ‘linked data’ versions of their datasets (e.g. the ‘Linked Open British National Bibliography’). Such services normally form part of an NBA’s wider ‘open data’ initiative.

A number of general tutorials on the topic of linked data are available and IFLA has a Semantic Web Special Interest Group devoted to the topic. In addition, the final report of the W3C Library Linked Data Incubator Group contains much useful background information.
