I have my library listing all the books I checked out. I have a pdf/epub reader that has a history of the books I read(although a new phone will probably wipe that out).
For a while, I was merely writing down my books in a dedicated notebook, but I realized that it didn't really matter, if a book was important, I remembered it. If it was bad, I forgot about it. I could have typed these into google sheets so it was sharable. I wonder if that is an acceptable option.
