Dear Dimitris,

  Thanks for your response.  Sorry, I don't know how
to 
  attach the link to Andrzej's post, but you'll find
it
  in the Archives : Sun. 24 March 2002, under
  Re: Re: Sinh[y]/y as y->0?

  I think I've understood it now :

           Normal[f[x]+O[x,a]^n]
 
  gives you the Taylor series of f[x] about x=a, i.e.,

  same as

           Series[f[x],{x,a,n-1}]//Normal
  
  That's most probably documented somewhere, but I 
  haven't seen it yet. It's not in Help.

  So that would explain the behaviour at a
singularity.

  Best Regards.

  Ajit.
