In reply to Sam Beaton:
> Thanks. I don't have the library tab,
On my android it is called "Downloads" and there's where you see all the 'books' ordered by different countries. From there, you click on the 'book', say Peak Limestone, and you'll see the dustbin icon next to ones you have downloaded, as Graeme said. Delete them by clicking on that.
By the way - I'm going lots of routes similar to you by the sounds of it, 5 and 6 sport routes in the Peak. I've found that for some crags, actually you need more than Gary's website and the Rockfax App, and actually the UKC logbooks are as close to definitive as you can get. I don't remember not having mobile data at any of the sport crags, so I often use UKC logbooks in addition to sportclimbs.co.uk and the app. Goddard's Quarry is a good example, lots of 5s and 6s but not everything is on the app and I think a bit less again on sportclimbs.co.uk. And if you climb in the low 6s like me, Goddard's is the source! Sheffield Tape Archive (6a+) should be a regional if not a national classic. You're really missing out if you're not climbing there.
