Search the Smithsonean Online Collections for 'Vanguard' (although mostly Vanguard 1 related - they even have poor little battered TV3)

For the first Vanguard that was successfully launched (the 'grapefruit'), I'd guess there is sufficient coverage all over the web, so just a few more unsorted links:
