It can be achieved with equipment used, in recording medium, in post, print, tilt, angle, it can even go into minute details like consistency with focal distance. As for the more direct answer to the question, strict organization is your best friend. Rating, keywording and grouping photos regularly will net a good base from which it is possible to draw photos faster. Then, when there exists a smaller batch, it can be pruned and further organised as a complete work. A good tool for that is printing small samples and making a collage out of them.
