When working with a package in GOKb, you may wish to add some manual enhancements, such as adding missing TIPPs, adding publication history information and previous titles, or populating other fields manually. It's really a matter of judgement regarding how much manual enhancement you do. You'll need to evaluate what's missing, the number of titles affected, and the amount of work required.
Once you're confident that your data is complete, you can finalize the package status.
