For those of you who who are struggling with the citation part of your dissertation you need to discover Zotero.
Zotero is a piece of free software that can be used to collect your citation information from the internet or manually and insert it into your dissertation using Microsoft Word or Open Office. The software is easy to install and set up and there is loads of help on the website and through associated forums.
Zotero only works with the Firefox browser on both PC and Mac but not with Internet Explorer or Safari, don't ask why it's a long story.
Zotero comes in 2 parts, a Plug-in for Firefox and a plug-in for Microsoft Word or Open Office.
If you do not normally use Firefox it is an open source browser by Mozilla and has an excellent reputation, personally I would not use anything else. You can have both Firefox and IE on your computer at the same time. Download Mozilla Firefox here
