hi, i am wondering if anyone can give some advices.
i am planning to do some study on language contact between users of
anglo saxon and of  old norse.
 
1. Is there any good article or book as for introduction to be recommended?
(Currently i have only got otto jespersen and matthew townend on hand, which i found quite helpful.)
 
2. Among old norse source, is any source commonly regarded good material for picking up anglo saxon elements?
(i assume i should avoid skaldic poems as my purpose or focus will be on language instead of literature analysis)
 
thanks for any suggestions. and i would like to say you guys are all very excellent in this.
