I've obtained the 1958 paper behind A000063 and A000131 and added further 
explanation of what is being counted, extensions, formulas and b-files.  
(It would be reasonably straightforward to add generating functions based 
on the formulas, though I don't think those would be particularly 
illuminating.)

Is there a current list of low-numbered or old sequences that it's thought 
might reasonably be extended or have b-files added given better 
information about the definition or about methods for calculating the 
sequence?  (Perhaps the wiki would be a good place for such details of 
sequences that have been found problematic by those who've tried to 
systematically compute lots of the early sequences?)
