I know the feeling. Around the time Amiga Format went belly up, I completed a Stalin-like purge of my Amiga stuff (sold most of it though). Man, did I regret it a year later. Wisely, I boxed up but held onto my A4000 and A3000 machines (both 060s).
A year or so ago I discovered Amiga.org....the rest is history
Nowadays the only thing that goes to the bin are the M$ AmigaBasic manuals that come with the odd A500.
