This book provides food for thought when looking for a market for photography. As I'm in social care and photography issecondary for me, I have been able to seek out markets for articles needing accompanying photos. Helpful guidance about the potential for placing work too.
For freelancers (or would-be freelancers) this is a long list of potential customers along with a basic description of what kind of photos they want, any technical criteria (min file size etc) and how to contact them. In most cases it gives indicative rates too. It's not bedtime reading but it is an effective reference.
Great for providing info on who wants what and how they want to be approached. Indispensable for a freelancer. Book comes free with subscription though, so consider this first, but as a standalone prOduct it is great.
