Hmm I think I will add a twist to mine.
First no time limit or particular order.
Second four alphabets
1) Author surname alphabet
2) Author First name
3)Title
4) Mish-mash for the books that don't fit - in this order, last word of title, author's middle initial, publisher, something else.
Theoretically based on mount tbr but as that is ever expanding and probably boundless really what appears next in the hand
