Hi Folks
I just discovered by chance that this most awesome 422 page book is now available free-of-charge (open-access) online. There is probably a third edition out now, but I doubt that it changes much from this edition, which is very comprehensive. Those doing content analysis in your doctoral thesis, you might find that you need to use very comprehensive specialist content analysis handbooks such as these.
If you said in your thesis "I use content analysis" to scrutinise data, I think your examiner would frown. My personal opinion is that you need to say e.g. "I use content analysis methods such as narrative analysis, policy analysis and critical discourse analysis to ....". This handbook has very specific discussions about content analysis for film, media, classical literature etc.
Enjoy
