[Koha] import records in marc display formats?

[smurfett at gmail.com]

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!
