# 19 Social networks

The most important social network for libraries has become Facebook just because it's the biggest. Probably everybody who uses a social network uses Facebook so it's stupid not to join in. And it's not restricted to people but also to organisations and groups.
One of the things I have discovered recently is Spotify and its social side. The library in Breda has already joined Spotify initially to promote their new cd's to be found in their playlist tips for juli 2010. This is a primeur I think, well done Breda! We will follow soon in Haarlem.
For the social aspects has Spotify linked with Facebook. If you are a registered with Facebook then you can automatically link with the playlists of your friends and "subscribe" if you like. The public can add their favourite muziek and comment on that of others and with the library.
This is a very easy and attractive way of connecting with the library public.
So as soon as the library in Haarlem has its Facebook page then we can use Spotify socially.

# 17 Pearl trees

I found it difficult to find a 2.0 website that did not just duplicate the ones we already know. And try and find one that is interesting enough to use as an example in a library context.
I don't think Pearl trees is that well known. Their website puts it succinctly:

Pearltrees is the social way to organize, discover and share the stuff you like on the Web. Use Pearltrees to keep at hand the stuff you find everyday on the Web, to discover new stuff in your areas of interest and to drive people through your web.

I think that there is enough potential here for the librarian to promote a number of products and items of interest for the users of the library. The sharing idea is useful as well as conneting with others who might have the same interests.
And it looks good.
