To get the "By the Book" achievement you must complete 100% synchronization across all Main Story sequences; you do not need to achieve 100% on side missions, collectibles or side activities. This achievement can only be obtained by completing each individual memory in each sequence and their respective optional objectives.

If you would like a detailed written guide on the optional objectives and how to obtain them, Morbious17 has added a great solution on the 360 achievement list. Incidentally, destinee ehgc has posted Morbious' guide as a solution below mine (or above depending on votes).
If you prefer visual aids to assist with achievements I have included videos further down the solution.
EDIT 01/11/2014: Solution was reported and the videos that were previously in this solution removed and replaced with a link to IGN's videos for Assassins Creed Black Flag.

How to View your Progress/Replay past Memories
You can view your synchronization percentage at any time by pressing the Menu button (button with three horizontal lines) on your controller and selecting "Progress Tracker". The 13 white/gray vertical lines on the left represent each of the 13 main sequences from 1 to 13 (Epilogue). Above these it will show your current percentage completion across all main sequences. Highlighting each of the vertical lines will give you an overall synchronization percentage for its respective sequence. By pressing A on any of the sequences, you will be presented with the list of memories within each.

To replay a memory, scroll up or down using the left stick until you see the memory in that particular sequence you wish to replay and press A.

Each memory will state the current synchronization percentage achieved and lists the optional objectives (if any) to be completed. Please note that not all memories have optional objectives. Completed objectives are yellow with the bullet coloured in, whereas objectives still to be completed are white.

You need to complete the memory from start to finish to register any optional objectives you have unlocked. Do not abort the memory after completion of optional objectives because it will not save your progress and you will have to do them again.

Additional Information
- Thanks to Jodmeister for giving some very useful info. regarding objectives which require you to "Stay out of combat";

"You can assassinate from cover and not lose the 'no combat' objective. Also the berserk darts are your friend for the no combat constraints as you can kill and distract at distance from concealment."

It's important to note that the Blowpipe, along with Beserk and Sleep darts, are not available until Sequence 4, Memory 4. For the staying out of combat objectives before this, I would advise you to take your time to see the routes where guards go and to gauge where you can either get past or assassinate them from cover.

- Thanks to PackageDonkey who has also provided some useful information regarding the 'No Combat' objectives;

"To add, I (Edward) was spotted in a no combat sequence, booked out of the area before any actual combat and still got the no combat objective."

This is when the radial minimap turns yellow; they have spotted you however you are still in a 'No Combat' scenario. As long as it does not turn red and ring the alert sound you can still earn the objective.

- You do not need to complete both optional objectives at the same time to gain 100% on each memory. You can complete one optional objective and then replay to focus on the other. Thanks to RSDAY for confirming this.

Due to the reporting of the solution there is now a link to where these videos can be located which I hope will assist with this achievement. All these videos have been posted on Youtube by IGN; I take no credit whatsoever.

Thanks for taking the time to look through my solution; I hope you found it useful. Incidentally if there is any additional information you think will be helpful to include please feel free to leave a comment and I will credit you for your input.
