Referencing all those journals - the lazy way

A page of thumbnail shots from one of my wildflower journals

I recently had reason to refer to something in an old journal, and it took me only 3 minutes to find it.  Knowing you journallers as I do, you, too have many, many volumes to keep track of.  I know there are people who have the discipline to number pages and create indexes but that's not me, and that's not how I recall information.....I recall events by the pictures I drew of them.  So, upon completing each journal, I photograph the cover and all the pages and print a contact sheet with thumbnails of every page.  I label the pages and pop them into a binder, divided by category (regular journal, garden journal, travel, etc.)  I can flip through those pages and find what I want very quickly!
