Access to MEDLINE pre-1981?

[W R Bennett]

Our university, as with many others, has a license to access MEDLINE and 
SCI, but these databases only go as far back as 1981.  Anyone know if 
there's a (free) gateway  which would allow me to on-line search for 
abstracts as far back as 1970 in the life sciences?  (I realise it's not 
very likely, but you never know...)
