title_body: Are there any ebook libraries in the UK Are there any programs that allow library books to be checked out, as ebooks, specifically in UK?
  
  NOTE: Based on this meta post and this question, I have created this UK version of the question.
upvoted_answer: In the UK you can (I suspect it depends on the county/borough) borrow ebooks from your public library.
  
  They use Overdrive as I suspect many others do, so I think only do ePub readers(and only those that understand Adobe DRM), so no Kindles. Overdrive does do Kindles but only in the US.
