If I don't add a novel to the bookshelf, I can find it in the following ways: 1. Search my bookshelf to see the list of novels I have read and find unread novels; 2. Find the novel folder on my device, usually in the reading or documents folder; 3. Search for the name of the novel in the search engine. If you find a relevant website or online reading platform, you can read the novel there; 4. I'll share the novels I've read through social media platforms and ask others to help me find them. If the novel is already on my bookshelf but I don't want to read it, I can choose to delete it.
