[Slling-l] Paradigms in sign languages?

[KIKUSAWA, R. （菊澤律子）]

Dear SL Linguists,

My colleague and I are interested in investigating patterns of paradigm levelling in sign languages.  We have been looking for descriptions of grammatical paradigms in sign languages, and also, any description of historical change that occurred in lexical items that form such a paradigm.  If you are aware of such work, would you kindly refer us to it?  We are still in a beginning stage and any information that appears to be relevant would be appreciated.  

Thank you very much in advance for your help.
