Dear listmembers,

I am back again with a request for copies I have problems with to get.

fall out of the subscription period.
Please, help me to get copies of the references listed below - I want
them for my book I am working at.

It looks like a long list, but it is just a small selection of the
material I still want copies from. I will be gratefull to anybody who
can help me with this.
