I have LR5.7 on Mac. The Blurb booksmart plugin is missing, how do I install it?
Blurb Booksmart is not a plugin for Lightroom, it is independent software you download and run.
Lightroom has its Book module built-in, nothing to install!!. And I believe much easier to work with images within the LR Library than having to export all the photos for Booksmart.
There may be differences between the LR Book Module and Booksmart, but that is the choice you need to make.
