Working in the Book module in LR and created something just for practice.
I don't want to keep it or publish it.
How can I remove it and be ready to start a new book at some time in the future?
Check the Collections panel at bottom left of Book module. If you saved the book it can be deleted by simply trashing the collection. Alternatively, you can just use the Clear Book button at top right corner of Book grid/loupe area.
Thanks for your speedy reply! Don't know why I never saw the "Clear Book" button.
