The Personal Author field should be filled in as in bibliographic references: the author’s name is usually entered in reverse order, with the author’s last surname followed by the first name.

Example:

Souza, João Paulo de

However, in cases where information such as Filho, Neto, Júnior is included, the surname preceding this information should also be recorded.

Example:

Souza Filho, João Paulo de

For author names in Spanish, the middle surname should be followed by the last surname in the surname field.

Example:

Contreras Toro, Laura Beatriz
