[Koha] Importing biblio fields from CSV

Hi all, I am trying to import biblio items (biblionumber, author and title is all I have) into Koha. It is in .dbf format and I can play around with it in Excel and change it into a CSV format. So far, so good. I imported 800 borrowers straight into MySql this way without a hitch, using LOAD DATA INFILE. All information shows up nicely in Koha. Now I tried the same thing with the only 3 fields I have for books, (biblionumber, author and title) but absolutely nothing shows up in Koha. It is present in MySql, I entered it into the biblio table. Did I miss something? I appreciate any help, I do not want to enter 6200 records by hand...
