Good point. It's often said that if there's no written record then it hasn't been done. But it's not quite as simple as that. There's been a cultural shift since the 70s/ 80s (and even possibly the 90s), when the FAs of micro routes on rock other than grit weren't normally recorded. This was also often true of routes in obscure or remote locations as well. At the time people commonly thought that such climbs would either be of no interest, or had been done before and not recorded. There wasn't the obsession with recording everything as there seems to be today.
Recording of FAs during this period was also far less straightforward than it is today. You had new route books in certain places which tended to cover certain geographical areas only (eg. in Snowdonia there was Wendy's Cafe, then Pete's Eats in Llanberis; Eric's Cafe in Tremadog) and the CC Journal. But if you weren't in the CC and climbed stuff in areas outside the scope and coverage of the new route books ....
So the new routes we climbed on obscure outcrops in the Moelwynion in the 1970s simply went unrecorded. Similarly we did a new route on a remote mountain crag in Ceredigion in 1979. We briefly discussed recording it, but didn't, as we had no idea at the time as to where to record a route that geographically was so far away from the mainstream of Welsh climbing. Interestingly, this particular route was re-cleaned and climbed again in 2013. Not surprisingly, before re-cleaning, it looked as if no one had been up it before, such was the effect of over 30 year's worth of neglect and regrowth.
Basically you can never be absolutely sure that something hasn't been climbed before. Best advice seems to be to claim it and then wait and see.
