I've recently started working for an employer in publishing. Not having worked in this field before, it's a bit of a learning curve. My employer uses a couple of places to advertise, and one agency. I'm keen to know if there are any particular publishing agencies that people recommend, and websites too where we can advertise our roles in publishing (in case there are better options than what they are currently using). They already use LinkedIn and Facebook for advertising, as well as the IPG.
Thanks in advance for any assistance provided.
