Thanks. In lack of the right importer I created
Catmandu::Importer::MARC::Pseudo:

https://github.com/LibreCat/Catmandu-MARC/commit/ee12f3dcfb98c5d16980c470f7bf75b16a5d2965

Could anyone help out with how to convert Leader and control fields? 
Lack background knowledge in MARC I cannot make any sense of this:

Leader/00-23 	*****nam##22*****#a#4500
007/00-01 	ta
008/00-39 	820305s1991####nyu###########001#0#eng##

Cheers
Jakob
