I often borrow books from the likes of Subscription Services like Kindle Unlimited and Scribd, and also from my local Library.

I think it would be nice to be able to track WHERE you have got the book from, similar to Owned that indicates it is physically on your bookshelf, I would like to track books that are available on Scribd, Kindle etc so I know where I can find a TBR book instead of having to search all services to find it.

I have been using tags to track this so far but its a bit clunky 😅

This could also tie in with a store you have bought a book from perhaps? Stat tracking also of what % each year you have read from a library vs bought from WHSmiths, Waterstones, B&N etc...
