The Index is dedicated to organizing your time and life. Field Notes identified specific ways that lots of folks are using the memo books, and made this edition useful for that. All the Index Edition books contain a handy pocket in the back for receipts, baggage claims, or an emergency cash. Also, due to the pocket, the middle spread of each book reveals something that has never appeared in a previous Field Notes Memo Book: a secret fourth staple. Log Book The first pack contains two Log Books with spaces dedicated to record, rate, and review anything you can think of… places visited, milestones, tacos tasted, trails hiked, books read, concerts, baby’s first words… The layout includes a space for a drawing, ticket stub, map, label, rubber stamp, or a photo from a pocket printer. These books are as flexible as they are useful,  with a table of contents and a key to your layout in the front, and ample room for notes. Ledger & Date Book The second pack contains one Ledger Book to track expenses, card game scores, mileage, steps, a shopping list, or just about any collection of items or numbers. This pack also includes a Date Book, containing a year’s worth of weekly planning pages. It’s undated and can be started anytime to track appointments, meetings, concerts, to-dos, etc. Just the place to write something down to remember it later. It’s also useful as a very brief diary!
