Book Tracking was an online reading platform that allowed users to find published novels and to receive regular updates. However, not all novel updates came from the Book Pursuit. Some authors might choose to publish their novels on other platforms instead of updating on the Book Pursuit. In addition, the novel updates on the book tracking device may also be affected by the author or editor. Some novels may stop updating for some reason. Therefore, although the Book Tracking Device was a convenient platform, it was not the source of updates for all novels. Sometimes, authors or editors would decide not to update their novels on the Book Tracking Device.
