One of the wonderful things about technology and the internet is the opening up of previously restricted collections in art galleries, museums and libraries. Increasingly these institutions are digitising their collections and making them available to the public online. Can’t get to New York to visit the Met? Browse over 40,000 artworks online from their collection in the comfort of your loungeroom. Interested in photography? Wander through more than four million photographs at The Europeana Collections website. Looking for a score for some Bach or Tchaikovsky? Go digging in the IMSLP/Petrucci Music Library database. Or do you fancy a little high end colouring? Quite a few institutions have created colouring books from their artworks that are free to download and colour at your leisure.
