For names of persons living in countries where orthographic reform has taken place (e.g., Indonesia, the Netherlands, Portugal, Soviet Union), if the first item received gives the person’s name in the old orthography, establish the name in that form. Make one reference from the form in the new orthography but only if the primary elements of the name are affected (cf. LCRI 26.2.).

Example A

When, subsequently, the first item with the name in the new orthography is received, change the heading to reflect the new orthography. Make a reference from the earlier form without regard to the primary elements of the name.

If the person’s works issued during his or her lifetime are all in the old orthography and posthumous publications begin to show the new orthography, delay changing the heading until 80% of the file agrees with the change to the new orthography. Make a reference from the later form without regard to the primary elements of the name.
