Hello Jessica,

The answer to your question depends on what do you mean by “additional columns of data” to be added?

If you are looking to import new book information, then no, there is not a way through the program to update the book information, but there are ways to add books and edit that information to be what you need it to be.

If that data is just some additional values being added to the General information, Yes, you can do an update import to populate that new information. See How to import changes to existing assets for more information.
