Good topic – I was just looking this up the other day, and getting frustrated by the lack of a specific answer.

I should add an earnest plea to the U.S. Geological Survey: Please, please draw up a new world plate map for us, one that comports with current practice.

If you wanna get into something really sticky, check out the boundary between the North American Plate and the Euasian plate (Sea of Okhotsk area). Not only is it poorly defined (many plate tectonic maps neglect it all together), but there are several possible microplates along it. From what I’ve seen, it is apparently such a slow relative motion between the plates that it is barely expressed tectonically, leaving it hard to explore the tectonics. Of course, the weather doesn’t help either.

So it’s not just me !…. I got out an old globe last week so I could mark out the plate boundaries.Obviously I searched for maps of tectonic plates and boundaries so I could get it right. Not so easy …they don’t all agree.
So I ended up with my own interpretation as a synthesis of the data I had looked at.
