The built-in Limit function only knows about elementary functions and things for which it can construct power series expansions (no essential singularities, etc.). The Calculus`Limit` package knows about a far broader class of functions and uses a more powerful algorithm. In[1]:= << Calculus`Limit` In[2]:= Limit[BesselI[I + eps, 1],eps->0] Out[2]= BesselI[I, 1] It is likely that some version of the algorithm used in this package will eventually be used to extend or replace the built-in code.
