I have a lot of files of book lists. Books I have read to the ducklings, which I might want to read again, to them or to a younger batch. Books I might want to read to the ducklings someday, but which they are still too young for. Books I want to read. Books I have read and now want to buy. Books I don't want to read (to save myself the bother of checking them out again).
Unfortunately, I have had no system of naming these files. So they're all named things like "Book List" "Reading List" "Books to Read Again." I usually have to open two or three files before I stumble upon the list I'm actually looking for.
It finally occurred to me today to at least name my personal reading list, the one I am most often looking for, "MY PERSONAL reading list." Now I hope that I can at least find it again on the first try.
