Legal deposit libraries have archived the web for over a decade. Several nations, supported by legal deposit regu-lations, have introduced comprehensive national domain web crawling, an essential part of the national library re-mit to collect, preserve and make accessible a nation’s intellectual and cultural heritage (Brazier, 2016). Scholars have traditionally been the chief beneficiaries of legal de-posit collections: in the case of web archives, the poten-tial for research extends to contemporary materials, and to Digital Humanities text and data mining approaches. To date, however, little work has evaluated whether legal deposit regulations support computational approaches to research using national web archive data (Brügger, 2012; Hockx-Yu, 2014; Black, 2016). This paper examines the impact of electronic legal deposit (ELD) in the United Kingdom, particularly how the 2013 regulations influence innovative scholarship using the Legal Deposit UK Web Archive. As the first major case study to analyse the implementation of ELD, it will ad-dress the following key research questions:• • Is legal deposit, a concept defined and refined for print materials, the most suitable vehicle for suppor-ting DH research using web archives?
• How does the current framing of ELD affect digital in-novation in the UK library sector?
• How does the current information ecology, including not for-profit archives, influence the relationship between DH researchers and legal deposit libraries
