Queen Victoria's diaries have been put on line - all 40,000+ pages of them!
http://www.queenvictoriasjournals.org/home.do The pages are scans, mostly of the Queen's writing or copies made by Princess Beatrice, although some entries were apparently typed up by Lord Esher - all extant versions are included. This sometimes means that some apparently boring days exist in several versions, while e.g. the first assassination attempt (june 10th 1840) is only in Princess Beatrice's copy, and is occasionally difficult to read. But it's a staggeringly complete record of the period from a unique viewpoint, and well worth a look if the period interests you.
