How much information on the "Identical Strangers" experiment was actually released? I am in the process of researching the Nature vs. Nurture debate. 

While I was searching for articles on it, I discovered something known as the "Identical Strangers" experiment (that probably was not it's real name, but it is the name of the book that the twins wrote about it). It was an experiment done in the 1960s where 2 identical twins were separated at birth and raised in different homes. The study looked at how they developed. 

I noticed when looking it up that there was something that said that details about the full experiment were locked away until 2066. My question is:

Is there any part of the experiment that has been documented (it can even be from the adopted parents, it doesn't necessarily have to be from the study itself) that is publicly available, or is all of it locked away at Yale University for the next 54 years?
To learn about other twins reared apart, investigate the earlier Minnesota Study of Twins Reared Apart and the ongoing Minnesota Twin Family Study.

To pique your curiosity:

Jim Lewis and Jim Springer stand out in the Minnesota Study of Twins Reared Apart because some of their two histories were strikingly identical; several notable examples:


1st wife: "Linda"
2nd wife: "Betty"
Dog: "Toy"
Cigarette: Salem
Job: Sherrif's deputy
built a circular white bench around a tree in the yard
