1. Main series is unnumbered:

LC practice: Do not give separate series added entry for the main series unless the main series has already appeared by itself on other publications. Instead, give a series added entry for the main series/subseries combination. Derive the series added entry or make it explicitly, depending upon whether the series statement and the numbering of the subseries (if the subseries is numbered) are in exactly the same form as the heading and form of numbering on the series authority record.

440 #0 $a Progress in nuclear energy. $n Series V, $p Metallurgy and fuels

490 1# $a University publications series. The social sciences ; $v no. 4

830 #0 $a University publications series. $p Social sciences ; $v no. 4.

(made-up example)

Exception: If the main series appears on a later publication without any subseries, at that point establish the main series separately and make the series added entry separately for this and any other item showing only the main series. However, if later forms show both the main series and a subseries, use in the added entry only the form in which the subseries is already established.

2. Main series is numbered:

LC practice: Give two series added entries: one for the main series and one for the main series/subseries combination.

490 1# $a Biblioteca de arte hispánico ; $v 8. $a Artes aplicadas ; $v 1

830 #0 $a Biblioteca de arte hispánico ; $v 8.

830 #0 $a Biblioteca de arte hispánico. $p Artes aplicadas ; $v 1.

3. Hierarchy of numbered and unnumbered main series/subseries:

LC practice: If a hierarchy of main series and multiple subseries is involved and only some are numbered, treat the unnumbered ones under 1. above and the numbered ones under 2. above.
