Journals, planners, and more

Gotcha. For that level of flexibility, a binder or discbound system is really ideal - whenever you start a book, you can fill out your "start page" format (giving details on it), and then just keep filling pages with discussion of that book as you'd like, adding them in after that start page until you're done. (This is assuming that you want to have all your discussion of one book together.) This would allow you to write about the books at different times, but order them manually so they're all together.
