When I was very young, pre-internet, we had a book at home (my other half's family had the same book).. It was called "Pear's Cyclopaedia", a single volume encyclopaedia.
It held the exact same result as a Google search now, I frequently remember people looking up medical complaints and assuming that the worst scenario was true. The sheer number of serious medical issues that we apparently suffered was amazing. Of course despite this none were ever real, it was the worst thing to have around for anybody that is remotely prone to worrying.
