Week 3: tasks 7 & 8: social bookmarking and tagging

Task 7: Explore different bookmarking sites such as Delicious, CitUlike, Connotea, and PearlTrees. Join one and connect with other users; blog about your experiences.

Task 8: Explore social cataloguing sites such as LibraryThing and WorldCat. Begin your own bookshelf, share details with colleagues and comment on their collections.

Pearltrees:
I signed up to www.pearltrees.com in March 2012, at the then B&PC LRCs Manager's request. LRC staff were invited to team up with the B&PC LRCs Deputy Librarian's LRC Tools Pearltree. 
I created one Pearltree myself, of the B&PC LRC social networking & eResources.
I'm afraid I didn't 'get it' and wasn't confident I could support tutors who chose to use them. 
In April 2012 this particular role was assigned to Lisa at NR LRC.

Other social bookmarking sites:
https://delicious.com - Keep, share, and discover websites
http://www.citeulike.org - Service for managing and discovering scholarly references
http://www.connotea.org - Discontinued on March 12, 2013 

Social cataloguing sites:
http://www.librarything.com
Interesting, but less so to me as I buy and store very few books at home myself as I work in a public library and so have quick, free access to almost any book I want to read, and I usually have 10 or so books on the go - I'm too busy actually reading books to go online about it!

I have explored this before and think its very interesting, although rather too US-centric; for example nothing from Dorset Libraries ever shows in its search results.
