Are the Tales a finished work?

I've read conflicting things from online sources, some say there's no answer to the question of whether they are a finished work, others say no, yet another source says GC planned 100 stories. So if this last source says that, then how is it not known whether they are finished?

EDIT: I just ran across another source that says 120 stories were planned! Which is it!

I think I read something about his scribe, who wrote that his employment by Chaucer came to an end when Chaucer died.

Well the General Prologue says every pilgrim will tell a couple of tales both on the outward and return journey. That plan was not finished and it would be probably too much if it was. But that was presumably Chaucer's plan.

As it is, as Dryden said, here is God's plenty.

(All from memory.)
