I'm helping to organise a doctoral forum next June which will be held in connection with CoLIS 7: The seventh international conference on Conceptions of Library and Information Science: *Unity in Diversity*.
If you're working towards a PhD in Library & Information Science, it might be worth having a look at the website to see if it appeals (http://colis.soi.city.ac.uk). Submissions are due next February.
Cheers!
