Question regarding MathWorld & Mathematica 10

What is the CURRENT best way of getting downloadable MathWorld notebooks to be usable with MMA10?

I have a MathWorld folder from an old MathWorld link for supporting packages loaded in AddOns/Applications Directory of my MMA10 installation. Most of the packages are 2007 vintage.

A number of MathGroup posts over the years have tried to find a clean way of accessing MathWorld from MMA without reasonable success.

In[2]:= << MathWorld`SpecialFunctions 

….. works OK

but, for the downloaded Mathworld notebook "AiryFunctions.nb" there is a missing context:

In[12]:= << DiscreteMath`RSolve`

During evaluation of In[12]:= Get::noopen: Cannot open DiscreteMath`RSolve`. >>

Out[12]= $Failed

I have run into many similar examples in the past of missing packages or changed/obsoleted functions not working correctly (or at all) that greatly lessen the value of downloaded MathWorld notebooks.

I hope the computable and curated mathematical knowledge of MathWorld is at the highest priority for clean access and use by Mathematica 10 & Wolfram Cloud users.
