Alas, no, we simply don't have the resources to do something like that. We are a shoestring budget operation.
One potential workaround is to scan your cookbooks into Goodreads (or LibraryThing) and then export them out and import back into Cookbooker. A bit complicated, I admit...
I am thinking about doing the same thing. I have 3,000 cookbooks. I have them mostly in Readerware and in Collectorz. It would be great if Cookbooker could import from a list of ISBN's...reason: it is fairly simple to create a list of ISBN's by exporting from one of the database programs like Readerware.
In meantime, I have been toying with workaround ideas like you have mentioned here, Andrew. (I do LOVE how you have "Add to My Bookself" buttons everywhere in Cookbooker. Very handy!!!)
