The Facebook page I've selected for my evaluation is from the National Library Of Australia. As this is a government organisation it is a highly authoritative site. The NLA uses it's site to provide information such as location and opening hours, to promote events and showcase it's collection. An example of this is the post about how historic knitting patterns are the most popular item searched for in one section of Trove (http://trove.nla.gov.au/ndp/del/article/71384389).
It is current (the last post was 22 hrs ago) and appears to be updated regularly. It has been liked 6,116 times and has 188 people talking about it. The variety of material available through this site makes it an interesting one to explore to learn about the National Library and some of it's treasures.
