Faced with a 385 page hardback history book (on the role Indian soldiers played on Gallipoli) to read and review I settled down to get through it on Saturday morning and got to the end midmorning Sunday : with notes. Best practice is then to read it again - right away. You can be suprised by what you missed the first time, so much so that it feels like reading a different book. More notes then write a review. I used to type up those notes: no more. The review is an adequate aide memoire.
