Re: [Phys-l] what's wrong with this picture?

I'm not a careful reader, so my thought is it's already passed into the public domain if it wasn't renewed timely.

Go to duration of copyrite (rites of passage)

bc googler, not a reader.

I few years ago during the PSSC 50th anniversary celebrations I suggested
to some AAPT and APS folks that it might be worth asking the copyright

domain, donate them to APS, or some such. The folks thought it was a
great idea, but AFAICT they never followed up on it. The last time I
asked for an update they didn't even answer my email.

I still think it's worth a try.
