Give readers the tools they need to build their own import files. A CSV specification with a list of required and optional columns of data would be useful for readers who previously used tools other than Goodreads or other common services.

I previously kept my Want To Read and Already Read lists in a big .txt file. I'd like to be able to take that file, format it to fit some specification with whatever columns are required, and then import it into my Want To Read/Read lists in Hardcover.
