[Koha] Validating bibliographic records

Hi, In our library we have two types of cataloguers: professional and non-professional ones. When a non-prrofesisional adds a record, we would like this record to b validated by a professional before being integrated in the running catalogue. Is there a way to achieve this ? Perhaps somehting that would let the non-professional enter the record as usually, but add it to the reservoir rather than to the catalogue ? Many thanks in advance for any hint, Sébstien.
