While filming The Lord of the Rings, I began recording my impressions in The Grey Book, one of the earliest blogs, launched before the term came into widespread use.
After that I began a new volume of entries called The White Book (see links below).
Originally posted like a blog, with the newest entries at top, in 2010 the entries were rearranged into chronological order from 25 June 2002 to 12 November 2003.
