I’ve gone fully digital with my reading.
Recently starting adding tag words to favorite quotes that is a word not found in the quote itself. For example I’ll add note “Favorite quote” with another tag work like “destiny” or “death” from my own defined list of categories. So to find quotes about destiny I’ll search for “Favorite quote destiny”. Easily searchable digitally without hitting on every “destiny”.
Saw at least 18 other ideas both digitally and analog.
Just wish I had started this system years ago.
