[Koha] import records in marc display formats?

Hi I'm sure this has been asked before but I didn't know what search terms to look for in the mail archives. I'm trying to catalog books using records from other libraries. Unfortunately, the only ones I can find are online and they display it in those nice marc formats like this: 001 054 020 09783848x8 100 1 $aLee, Harlety etc Is there some sort of script that will covert this web view into a nice marc record so that I can import it into Koha? thanks! nancy
