The Library has an extended online trial of The International Encyclopedia of Communication until 25 September, 2008.
Some people had trouble with this trial last time so the bugs have been fixed now.

This is a searchable online encyclopedia published by Wiley-Blackwell in association with the International Communication Association. It comprises over 1,330 newley-commissioned A-Z entries, divided into 29 editorial areas representing major fields of inquiry, each of which is headed by a leading expert in the field.
