Here's an edu site that includes original source material. It lists 19 people executed, one of whom was Giles Cory who was crushed to death.
In addition, it lists 5 having died in jail, 1 an infant girl.
This site has a lot of interesting source material
I few other details I remember from when I studied this in school:
It actually took place in Salem Village which is now called Danvers.
There was a great deal of tension between Salem Village and Salem Town and if you look at the location of the accusers and accused you see that one set came primarily from the town or had links to the town and the others came from the village (I'm not 100% sure but I think accusers were villagers trying to keep their way of life and accused were town trying to be more progressive).
A few decades later, a group of youngsters exhibited very similar symptoms but the mood of the country had changed and it was interpreted as being touched by god not the devil.
eta: OOPS. According to the memorial site, there are 20 memorials so it does seem to be 19 hanged and 1 pressed.
Also, here is a site with a lot of non-tourist links for further research.
ETA: another page of links
