When linking bib headings, Alma does not follow NACO comparison rules when checking for ambiguous headings. This results in numerous headings not linking at all, and being reported as ambiguous. This reduces the utility of Alma's authority control process, because there are too many headings to link manually.

Examples of headings that Alma won't link because they are "ambiguous"

• Peabody Essex Museum

• Peabody & Essex Museum

• Ciné+ (France)

• Cine France

• Mohammad, Ali

• Mohammad Ali (a cross-reference in the authority record for Ali, Mohammad)

• McFarland & Company

• McFarland Company (cross-reference in authority record for J. Horace McFarland Company)
