You need to use Comma Quoted
import.
Authors (most strings) are Quoted so those are a single cell
OTOH numbers do not have commas, so the use the comma as a column separator
EG
Code:
"62","2013-08-18T07:04:21-07:00","The Exotic Enchanter","","L. Sprague deCamp & Christopher Stasheff","Harold Shea","6.0"
Is an empty field
