Los Angeles residential architecture : modernism meets eclecticism / Ruth Wallach. (OCLC #913768383)

In MARC, we indicate the number of non-filing characters in the title using 245’s second indicator. For example, The cardturner would have 245 second indicator 4 to indicate that four characters should be skipped (The word ‘the’ and the space following it) and file it starting with the “c”, rather than sorting all of the “The…” titles together. Articles in other languages are also skipped.

This indicator seems like a value that could be easily detected/automated if the system knew which words were articles in various languages, which may be why it doesn’t appear in many newer cataloging frameworks. I worry that some would be detected incorrectly, such as in this title:

245 10 ǂa Los Angeles residential architecture : ǂb modernism
    meets eclecticism / ǂc Ruth Wallach.

Though “Los” is an article in Spanish, “Los Angeles” in this case is a single proper noun, so the word should not be skipped. (This particular case could be handled by also detecting the language, but a Spanish-language book about Los Angeles would have the same problem.)

I like Wikipedia’s method of handling this, which is to have a sort key (if it’s different from the main title) as a separate field:

{{DEFAULTSORT:Cardturner, The}}

Mappa mundi = Studia in honorem Jaroslavi Daškevyč septuagenario dedicata : zbirnyk naukovykh prat︠s︡ʹ na poshanu I︠A︡roslava Dashkevycha z nahody ĭoho 70-richchi︠a︡ / [redakt︠s︡iĭna kolehii︠a︡, Ihor Hyrych and others]. (OCLC #39024881)

This book includes materials in many languages, as indicated in the 546:

546 __ ǂa Predominately in Ukrainian with articles
    also in English, French, German, Polish, and Russian.

Its Lang fixed field is encoded for Ukrainian (as that is the predominant language) but other languages are encoded in MARC 041. The old standard for this field was to concatenate all of the three letter codes in one subfield, like:

041 0_ ǂa ukrengfregerpolrus

But now each language gets its own subfield:

041 0_ ǂa ukr ǂa eng ǂa fre ǂa ger ǂa pol ǂa rus

Кандидат на престол : из истории политических и культурных связей России и Швеции ХI-ХХ веков / Г.М. Коваленко. (OCLC #43227577)

MARC field 530 is a general note about the availability of additional physical or digital forms:

530 __ ǂa Also issued online.

More specific information goes into 776:

776 08 ǂi Online version: ǂa Kovalenko, G.M. (Gennadii
    ̆ Mikhaĭlovich). ǂt Kandidat na prestol. ǂd Sankt-Peterburg
    : Russko-baltiĭskiĭ informat︠s︡ionnyĭ t︠s︡entr BLIT︠S︡, 1999 ǂw 
    (OCoLC)60730009

Currently, MARC records in OCLC are created at the manifestation level, and this method can be used to link together different manifestations of the same expression.

Up all night with Robert Downey Sr. [videorecording] / directed by Robert Downey Sr. ; screenplay by Robert Downey Sr. (OCLC #793654441)

When you are cataloging a collection of works on one record, the individual titles of those works should be recorded as analytical entries:

740 02 ǂa Babo 73.
740 02 ǂa Chafed elbows.
740 02 ǂa No more excuses.
740 02 ǂa Putney Swope.
740 02 ǂa Two tons of turquoise to Taos tonight.

No relationship designator is needed; it is already encoded in the MARC: in 740, second indicator ‘2’ designates the field as an analytical entry. The first indicator is the number of non-filing characters in the title; however, current practice is to always use first indicator ‘0’, and just enter the title without articles or other non-filing characters.

Cotton / edited by David D. Fang and Richard G. Percy. (OCLC #909779516)

When catalog electronic resources, I follow the Provider-Neutral guidelines (even if I only know of one instance of that resource) and label the provider in the 856 ǂ3:

Index of reports, 50th to 75th Congresses, 1888-1938. (OCLC #9796069)

There is a fixed field code for use when a book is an index to bibliographic material other than itself:

Cont: i

This code is not be used when the resource just contains an index to its own contents; there is a fixed field specifically for that:

Indx: 1

Nine seventeenth-century organ transcriptions from the operas of Lully / edited with an introduction by Almonte C. Howell. (OCLC #897477805)

The 048 field in MARC is for the Number of Musical Instruments or Voices Code. Each subfield $a typically contains a two-digit code for the type of instrument, followed by a two-digit number indicating the number of parts. This score contains pieces for a single organ player, so the code is:

048 __ ǂa kb01

All keyboard instruments start with k, and Organ is second on that list (ka is the code for piano).

Istorii︠a︡ grazhdanskoĭ voĭny i intervent︠s︡ii v SSSR : sovremennai︠a︡ burzhuaznai︠a︡ istoriografii︠a︡ / V.P. Naumov, A.A. Kosakovskiĭ. (OCLC #26511741)

Subfield ǂa of 050 is repeatable, and I often see this feature used for titles in a series. For example:

050 04 ǂa D410 ǂb .N652 1976, no. 11 ǂa DK265.9.H5

The first call number should be used if you class the series together under one call number:

D410 .N652 1976, no. 11

(That’s D410 for 20th century periodicals, cuttered on the romanized name of the series: Novoe v zhizni, nauke, tekhnike. Serii︠a︡ “Istorii︠a︡”)

The second class number is provided for those who class the series separately, with a specific call number for each volume. In this case, that is:

DK265.9.H5

(History of Russia, Revolution, 1917-1921, Historiography). Subfield ǂb is not repeatable, so no item number is provided.

We class this series separately, so I used the second class number, adding a cutter for the author, Naumov:

090 ǂa DK265.9.H5 ǂb N37 1976

Proceedings of the Second International Congress of Medieval Canon Law : Boston College, 12-16 August 1963 / edited by Stephan Kuttner and J. Joseph Ryan. (OCLC #4289022)

This volume has text in multiple languages:

546 __ ǂa Text in English, French, German, Italian, and Spanish.

which is also encoded in the 041 as:

041 0_ ǂa engfregeritaspa

This is hard to read and error-prone, as shown in a similar volume which had this encoded as

041 0_ engfregerha

There is no MARC language code “ha”; they are all three letters long. I have now corrected this record, and encoded in the current standard:

041 0_ ǂa eng ǂa fre ǂa ger ǂa ita

The king of desks : Wooton’s patent secretary / by Betty Lawson Walters. (OCLC #49110)

MARC field 019 is used in OCLC for OCLC Control Number Cross-Reference; that is, when two (or more) OCLC records are merged, one OCLC accession number is kept for the record, and the others are put into 019, each into its own ǂa like:

019 __ ǂa 253458412

Records can be merged when a duplicate is accidentally created, such as when a master record is not found for some reason, or when the cataloger did not realize that the differences between descriptions are not sufficient to justify a new record. They can also be merged when cataloging rules change; for example, many older ebook records have 019 fields from when the title was cataloged on multiple records (each specific to one vendor/aggregator), and have since been combined into one provider-neutral record.
