I’m concerned that their imaging software is making some sort of fundamental error, because the image I received is perfectly aligned horizontally and vertically, just that as I posted earlier it’s been targeted on the horizontal boundary between two records.
It seems to be because the page scans, done as part of the digitisation project some years ago, weren't positioned very accurately. Each page has a number of entries on it, so the new system just calls up the scanned image of the whole page and automatically crops it down to where the entry you want "should" be .... if the page scan wasn't aligned perfectly the image will be slanted or cut off at the top/bottom.
I've just had a refund for one, which took about a week - as compared with a day or two during the trial. It is a significant, but known, limitation of the system and probably causing a considerable number of refunds to be processed..
