The concept of “linking” can refer to two things: linking on bibliographic level and link on local items level.
- Different titles in the same series can be linked by the series title (MARC bib record 490+830 fields).
- Two or more bib records can be also linked by item records on local OPAC (here, Millennium).
In the first case, item records under each bib are not shared. In the second case, item records are shared with both bib records. In other words, the same item record will show up under either bib record opened.
Linking on bibliographic level is useful for regular series. In MARC environment, this is achieved by adding series title field (i.e. 490+830) in bib records made for each title. A search for the series title on the catalog then will retrieve all titles belonging to this series.
Note: There are some very complicated series in terms of multi-volume titles, complex numbering pattern, and the fact of being published over a long period. For instance, 十五年戦爭極秘資料集 (Jūgonen Sensō gokuhi shiryōshū) has 73(?) titles, and some titles cover more than one volume.
Linking at item records level. The linked-item-record feature comes handy when
(1) There is a stand-alone bib for the whole series*
(2) Special or additional issues of a serial title
(3) A serial is published in a way that each issue is an stand-alone title
*Note, there are exceptions!
(1) Link item to stand-alone bib (sometimes called a “container bib”)
Example 1. A small collection of irregular series
[Situation]
An order record is created for a multi-volume set (the set is relatively small). Each volume has a different title (and can be received in different time).
[Approach]
- Make individual bib record for each title
- Link each item to the bib that holds the order record — this bib maybe a very brief one
Examples,
This is not a “serial” (there is no indication anywhere of any volume or issue numbers etc.) and all six pieces have unique titles, but they seem to be related because “NHKは何を伝えてきたか” (NHK wa nani o tsutaete kita ka) appears on all six pieces. And, when the library ordered them, an “order-holding bib” was created. Because the individual pieces are so different, the order-holding bib bears little information about them (except the common phrase “NHKは何を伝えてきたか”). When we received these 6 volumes, we cataloged them as though they were unrelated (i.e. individual records were created for all six pieces). After exporting the records into Millennium, we linked all the six item records individually to the order-holding bib.
The order-holding bib used the shared title: NHKは何を伝えてきたか NHK wa nani o tsutaete kita ka (bib b64847585)

(2) Special issues of a serial
Sometimes a periodical will publish an additional or special issue with a unique title. We can make individual bib records for these special issues and then link the items to the periodical record.
Examples,
Serial title: 建築と都市Kenchiku to toshi = Architecture and Urbanisam (B11618334; OCLC#3010408)
This journal sometimes will publish an additional issue (臨時增刊) like this:
- ル トロネのアルヴァロ シザ : 経路と作品Ru Torone no Arubaro Shiza : keiro to sakuhin = Siza au thoronet (B40815389; OCLC#682542230)
This is an additional issue in Nov 2010. Other “regular” issues do not have unique title, and therefore are not cataloged separately.
(3) Serial with each issue being a stand-alone title
When a serial is published in a way that each issue is a separate title, we can make a bibliographic record to describe the serial as a whole, and then make individual bib records for each issue/title. In this case, the bib made for the whole serial is called the “container bib” record. The item record for each volume is linked to both the container and the individual bib records.
Examples.
Title: Palaeontologia Sinica. New series B (this is part of a larger serial in hierarchical form)
Container bib b45922901 Call number QE756.C6 A33
Individual issues include
- 华北及东北南部上寒武统长山阶三叶虫 / 钱义元著 b68322926
- 浙江西部寒武紀三叶虫动物群 / 卢衍豪, 林焕令著 b68322914
(4) Order bib stands alone – individual bib – no linking
[Situation]
The library ordered a large series collection. All volumes bear the series title. However, the publication is still ongoing, and library receives volumes not all at once.
[Approach]
- Make individual bib record for each title (note, sometimes, one title covers more than one volumes).
- Because the collection is too large, do NOT link items to the order-holding bib, leave the order-holding bib alone.
- The order-holding bib is suppressed on OPAC (so users won’t see it). Order unit staff will keep updating it when new volumes received.
Examples,
A Japanese series title 中西進著作集 (Nakanishi Susumu chosakushū) has many individual titles. The bib record b6266086x is just an “order-holding bib” and contains only order and funding information. And in this collection, some titles run into multiple volumes –
古事記をよむKojiki o yomu; 1, 2
日本神話の世界 ; 神話力 ; 神々と人間Nihon shinwa no sekai ; Shinwaryoku ; Kamigami to ningen; 3
etc.
万葉集全訳注原文付Man’yōshū zen’yakuchū genbuntsuki; 19, 20, 21
etc.
Note:
- These books come to us with a streamer bearing the “order-holding bib” number. We should not use this bib number, but make new bib records in stead.
- Cataloger may assign different call number for each title, but if we want them to be shelved together in one place, we will need to insert a common call number (also used by the order-holding bib) to each item record under in addition to their volume numbers.
