For the filing segment, Ayman Abou-Sada which of the following are true?

• A. The key unit is Abou-Sada
• B. There are three units
• C. A cross reference should be prepared
• D. Both A and C

Answer: (D)

In personal-name filing, the key unit used for the filing segment is the family name. For Ayman Abou-Sada, the key unit is Abou-Sada, not the given name. Because people may search by different forms of the name, a cross reference should be prepared so that retrieval under the surname Abou-Sada points to the full name as well (for example, guiding someone who looks up Ayman Abou-Sada to the Abou-Sada entry). There aren’t typically three separate filing units for a personal name—the surname serves as the main filing unit, with given names as display elements or non-key fields. So both the idea that the key unit is Abou-Sada and the need for a cross-reference are true, making the combined understanding correct.
