I don't know if people already know about this but this website - Issuu (link) seems to have magazines to read on it for free. A lot of the stuff looks not so great like health leaflets and stuff but Happiful Magazine (link) is good and I also found The Psychology Book (link). I'm not sure if everything is free and some things are just previews I think.
Just passing it on.
I put it down on paper and then the ghost does not ache so much.
