Here is the url for the relevant page onteh Sweet and Maxwell site. The journal is not available free.

Thoretically it would be an infringment of copyright in the article (definitely) and the journal (probably) to OCR the article and post it.

Sweet and Maxwell may not have got (apologies for my grammar) all the rights from the author and it may be possible in theory to get the necessary permission from the author direct.

Public library probably easier. The copy from them should not be a copyright problem - private research, see!

Good luck.
