The collections are subject to different institutional priorities, and preservation and access strategies are not co-ordinated.
Links between the collections are difficult to maintain.
However, item records show that many of the interviews have been migrated to a digital format (mp3 files are listed for listening purposes).
No information is provided about the digitisation, but it is likely that it was part of the BL's Archival Sound Recordings digitisation programme.
Registration is required for access to data; the service has a strong emphasis on UK higher/further education use, and although people without a UK HE/FE institutional affiliation can apply for user accounts, registration is a less straightforward process.
After registration, it is also necessary to register specific data usages of data outlining the uses that will be made of the dataset(s).
The dataset comprises 453 transcriptions, summaries, and a coded version for quantitative analysis.
Further information: UK Data service - How to Access The early decision to archive the audio collection and transcripts at separate locations was quite a rational response to the technological constraints of the time.
The BL catalogue contains no reference at all to the ESDS Qualidata dataset or web resource; the UKDA documentation and ESDS resource briefly mention the BL sound archive deposit, but provide no further information.
Digitisation took place with separate agendas and for different purposes.
The research materials were divided into separate collections for preservation and access purposes at a very early stage.
The audiotapes of the interviews - which had been recorded on reel-to-reel machines both for recording quality and long-term durability - were deposited at the British Library for safe keeping.
