On a related subject...

For difficult to obtain meteor-related articles, I use the document
supply service of the British Library - they have a very comprehensive
catalogue and offer a quick turn around.

The service includes payment of any copyright fee due.

Anyone know under what circumstances, or after how long copyright
expires, and it becomes permissible to make documents freely available
on the Internet? Do the authors / publishers have discretion in this
matter.
