Release Notes
https://github.com/kiwidude68/calibr...odreads-v1.8.3
@kevn57 - this should fix your issue of not wanting the Amazon.com identifier (it was a bug). You just need to uncheck the 'Get ASIN for kindle editions' option in the configuration options for this plugin.
Interesting on Storygraph, had never heard of it (not one of the cool kids I guess). Will take a look at it one day if I find time, if I end up using it then I will want a plugin for it too so would end up writing one.
