Thanks for alerting us to that Zephy - they are now linked. I've also linked the eBook and corrected the cover image.
If any members ever want a useful job, check on your unindexed books (the filter is at top right (or under the Menu on a phone) and see whether there is an indexed edition it could be linked to. We only link indexed books so don't bother letting us know about unindexed books that could be linked. If you find any then you will instantly get all the recipes, notes, member photos on your Bookshelf.
The easiest way to do the checking I think (if anyone comes up with a quicker method please do post here) is to sort the unindexed books on you Booksehlf by author. Then open the author page in another tab. Check if the titles you owned have any indexed editions they could be linked to. Let us know by email (Contact at top right) or by adding a Note to the book. Email is better as I check emails several times a day but I only check all the Notes when I have spare time (not often at the moment).
