Catalogo Cicognara Edge Cases

We have two sets of data records:

1. The MARC records from the microfiche (4,704 records)
2. The entries in the Catalogo (4,794 entries)

We must establish correspondences among them:

1. Every entry in the Catalogo ought to have a MARC record associated with it, because every entry in the Catalogo ought to correspond with one or more items in the fondo Cicognara and should therefore have been microfilmed by Proquest.
2. Every MARC record ought to have one or more corresponding entries in the Catalogo, because everything microfilmed in the fondo Cicognara should have been cataloged by Cicognara.

Acceptable Conditions:

1. Many Catalogo entries have more than one MARC record associated with them. This is because many of Cicognara's entries in his Catalogo describe more than one book.
2. Some MARC records have more than one Catalogo entry associated with them. This is because Cicognara cross-referenced or duplicated some books in his entries.

Problematic Conditions

MARC records without Catalogo entries

There are 14 MARC records that do not correspond with items in the Catalogo (see below). Almost all have 'n.C.n.' as a value for the Cicognara number; 'n.C.n.' most likely means 'no Cicognara number.'

Why are these MARC records included?

• Because they represent items on the microfiche?
• Other?
• What should be done about them?

Catalogo entries without MARC records

After normalizing the Cicognara numbers in the MARC records (i.e., removing the various supplementary symbols Proquest added to the Cicognara numbers while microfilming) and matching those normalized numbers to the Catalogo, there are still over 700 entries for which there are no matching MARC records. Possible reasons:

1. The items appear in the Catalogo but are not present in the fondo Cicognara in the Vatican;
2. The items are present in the fondo Cicognara but were, for some reason, not microfilmed.

What should be done about these?

• Should Mark Armstrong work through the Master Spreadsheet and other sources to establish possible matches now?
• How important is it for the application to have at least one MARC record for every Catalogo entry?
