Vitae is the UK organisation championing the personal, professional and career development of researchers in higher education. You can download 5 great little booklets from their website. The Informed Researcher is particularly useful.

The British Library’s Business & IP Centre recently highlighted their Industry Guides – as well as referencing a lot of print material in the library, they also include web resources. Handy if you need to research a particular industry!
