The document discusses the difficulties of text and data mining (TDM) for a research project between the British Library and several universities. It summarizes that: 1) While the UK copyright law contains a TDM exception, it was not drafted with research partnerships in mind and does not allow the British Library to share digitized content with research partners. 2) Practical difficulties in assessing and obtaining permissions for the huge amount of copyrighted content were addressed through high-level content analysis, spot checks, and managing risks. 3) The British Library addressed legal difficulties by having partners temporarily join the library and access digitized content on a secure server, then deleting the content after use.
