Recording parallel title proper (RDA 2.3.3)

The parallel title proper includes:

• ° an alternative title in another language and/or script is treated as part of the parallel title proper
• ° an original title in a language different from that of the title proper that is presented as the equivalent of the title proper

If an original title in a language different from that of the title proper is presented as an equivalent to the title proper, record it as a parallel title proper.
Examples:
2013560319
     245 10 Raíces = ‡b ("Roots")
2012564395
     245 10 Centenary song album = ‡b Jubiläumus-Liederalbum
2012563437
     245 10 Ah che la morte ognora = ‡b Ah I have sighed to rest me
2012396912
     245 10 Koncert pro violu a orchestr = ‡b Konzert für Viola und Orchester = Concerto for viola and orchestra
2010562251
     245 10 Melodie für Flföte, Oboe, Klarinette, Horn und Fagott = ‡b Melody for flute, oboe, clarinet, French horn and bassoon
2011568270
     245 10 Sonate za violinu i orgulje = ‡b Sonate pour violon et orgue
2012564397
     245 10 Barcarolle Fis-Dur, Opus 60 = ‡b Barcarolle in F# major, op. 60
          Note: on the resource "Opus" is spelled out in the German; it appears as an abbreviation in the English parallel title

     245 10 Melodie für Flöte, Oboe, Klarinette, Horn und Fagott = ‡b Melody for flute, oboe, clarinet, French horn and bassoon

If a parallel title proper is taken from a different source than the title proper, and that fact is considered important, make a note on the source (2.20.2.3)

Best practices for music cataloging:
If feasible, record all parallel titles proper appearing on the preferred source.
     Optionally, record parallel titles appearing elsewhere in the item.
Parallel titles from any source in the item may be transcribed in 245/‡b or ‡c, without square brackets.
Record the form in which the title appears on the source of information as a variant title if it is considered to be important for identification or access Parallel titles should also be recorded as variant titles (in the 246 field) to ensure proper indexing.

When a parallel title is taken from outside the preferred source and included in 246 (in addition to 245/‡b or ‡c), apply 2.20.2.3 (Note on title source) by including a note or or an introductory phrase in the 246/‡i.

Alternatively, parallel titles from outside the preferred source may be recorded only in 246 1_ with an introductory phrase in 246/‡$i.
Examples:
2012572074
     246 1_ ‡i Parallel title on caption: ‡a Ninnerella
2012564279
     246 1_ ‡i Parallel title in caption: ‡a Jin jiang ba jing

This approach may be preferable when multiple parallel titles appear in different sources, and therefore the second paragraph at 2.3.3.3 is difficult to apply

If the source of information includes statements of medium of performance, key, date of composition, and/or number that are treated as part of the title proper (2.3.2.8.1) in more than one language or script, record such statements in the order in which they appear on the source of information as part of the parallel title proper.

Examples:
OCLC #808842294
     245 10 Sonatina for violoncello and piano, C minor = ‡b für Violoncello und Klavier, c-Moll = ut mineur
OCLC #793653629
     245 10 Sonate für Flöte, Violine und konzertierendes Cembalo (Klavier), C-Dur = ‡b for flute, violin and obbligato harpsichord (piano), C major
OCLC #779254288
     245 10 Rêverie : ‡b für Violoncello und Klavier, g-Moll, opus 92/2 = for violoncello and piano, G minor = sol mineur

Some but not all of the key is in another language and the key is part of the title proper:
On resource:
     OCTET For 4 Violins, 2 Violas and 2 Violoncellos E♭ major/Es-Dur/Mi♭ majeur Op. 20
ISBD in MARC 245:
     245 10 Octet for 4 violins, 2 violas and 2 violoncellos E♭ major op. 20 = $b Es-Dur = mi♭ majeur
Explanation:
     The medium of performance, key, and number are considered to be part of the title proper because the title is a type of composition (2.3.2.8.1). Since "Op. 20" is linguistically neutral, it has been included as part of the title proper, even though it appears at the end of the title on the resource. For the parallel title proper, 2.3.3.4 applies since a statement of medium of performance, key, date of composition, and/or number is being treated as part of the title proper and the statement is in more than one language. Even though just the key is in multiple languages, it can be considered as a parallel title proper.
