The LKR field in Cataloging 3 Introduction The LKR field may appear in a record for two reasons: It has been generated by the system (system- generated) It has been entered by a cataloger (user-generated) We will first discuss system-generated links, then user-generated links

The LKR field in Cataloging 4 System-Generated Links The ALEPH system holds information in different types of records and different types of "libraries" (databases). For example, a standard system has a bibliographic database for storing bibliographic data, and an administrative database for storing administrative data. The total picture of a record is dependent on the links between the other records in the system. The LKR field is an ALEPH field used to create these links.

The LKR field in Cataloging 5 Automatic creation of System-Generated Links When creating a holdings or an administrative record for the bibliographic record in the Catalog module, the new record automatically includes the LKR field. The following is an example of an LKR field for an administrative record. Note that subfield $a of the LKR field (administrative record) is set to ADM and subfield $b contains the system number of the bibliographic record.

The LKR field in Cataloging 6 Bibliographic Record We have the following record in library USM01

The LKR field in Cataloging 7 Holding Record When the HOL record is created for the bibliographic record, it automatically receives an LKR field

The LKR field in Cataloging 8 ADM Record Similarly, when an item is created, an Administrative record is also created, and contains an LKR field.

The LKR field in Cataloging 9 Structure of the system-generated LKR The system-generated LKR field contains three subfields Subfield a: type of link HOL: link from HOL record to BIB record. Link is built from BIB to HOL. ADM: link from ADM record to BIB record. Link is built from BIB to ADM.

The LKR field in Cataloging 10 Structure of the system-generated LKR Subfield l: library to which record is linked In the examples here the HOL record and the ADM record are linked to the USM01 library Subfield b: system number of record to which current record is linked

The LKR field in Cataloging 11 Structure of the system-generated LKR This is a Holding Record linked to system number in library USM01

The LKR field in Cataloging 12 Structure of the system-generated LKR This is an Administrative Record linked to system number in library USM01

The LKR field in Cataloging 13 User-generated LKR field You can use the LKR field to create links from one bibliographic record to another for example for analytical purposes for changed titles for serial publications

The LKR field in Cataloging 14 User-generated LKR field The available types of links and the values that must be entered to generate these links are shown in the next slides. Note that the LKR field is only cataloged in one of the records; the system creates the other side of the link. First we will discuss LKR subfield a, then the other subfields

The LKR field in Cataloging 15 User-generated LKR field – subfield a UP An up link to another bibliographic record. A record can have only one link of this type. A DN link is automatically built in the opposite direction. DN A down link to another bibliographic record. Multiple links are possible. An UP link is automatically built in the opposite direction.

The LKR field in Cataloging 16 User-generated LKR field – subfield a PAR A parallel link from one bibliographic record to another. A PAR link is automatically built in the opposite direction. ANA The ANA link creates both ITM and UP-DN type links. In other words, it creates a link between the two bibliographic records and to the item/s. * Note that subfield $b for this type of link contains the system number of the bibliographic record to which the record is linked (unlike the ITM type link).

The LKR field in Cataloging 17 User-generated LKR field – subfield a ITM The ITM link creates a link between one bibliographic record and the items of another bibliographic record. The item filter fields ($y, $v, $p, and $i must be used for this type of link). *Note that subfield $b for this type of link contains the ADM system number.

The LKR field in Cataloging 18 User-generated LKR field – other subfields b System number of the linked record (the target record) i Issue link k Pages l Library where target record is located. It must be entered in uppercase

The LKR field in Cataloging 19 User-generated LKR field – other subfields m Down link note n Up link note p Part link r MARC tag link

The LKR field in Cataloging 20 User-generated LKR field – other subfields s Sort sequence; can be alphanumeric (more information on the way this field affects the display of the link can be found in tab_fix_z103) v Volume link y Year link

The LKR field in Cataloging 21 Up and Down links The DN (down) link creates a down link from the record that has the LKR field to the record to which it is linked. An UP (up) link is created automatically from the linked record back to the record with the LKR field. The UP (up) link creates an up link from the record that has the LKR field to the record to which it is linked. A DN (down) link is created automatically from the linked record back to the record with the LKR field.

The LKR field in Cataloging 22 Up and Down links Example: we have Sysno 67342: Economic History of Europe Sysno 67343: Economic History of Poland Sysno 67344: Economic History of Portugal We will make a DN link from to both and An UP link will automatically be created from and to 67342

The LKR field in Cataloging 23 Up and Down links Thus, in record we will add the following: LKR L $$a DN $$b $$l USM01 $$n The economic history of Poland $$m The economic history of Europe LKR L $$a DN $$b $$l USM01 $$n The economic history of Portugal $$m The economic history of Europe

The LKR field in Cataloging 24 Up and Down links And therefore when user views record in web OPAC he will see the following as part of the record: Clicking “The economic history of Poland” will link to record Clicking “The economic history of Portugal” will link to record 67344

The LKR field in Cataloging 25 Up and Down links And therefore when user views record or record in web OPAC he will see the following as part of the record: Clicking “The economic history of Europe” will link to record 67342

The LKR field in Cataloging 26 The PAR (parallel) link The PAR (parallel) link creates a parallel link from one record to another. For example, we may have two similar bibliographic records, and we want to tell the reader to see the other bibliographic record when he views one of them in the web OPAC. (Perhaps for example we have two editions of the same monograph).

The LKR field in Cataloging 27 The PAR (parallel) link Scenario We have record 67348: L $$a > Cambridge economic history of Europe;$$cgeneral editors, M.M. Postan and H.J. Habakkuk. 250 L $$a1st ed. And we have record 67342: L $$a > Cambridge economic history of Europe;$$cgeneral editors, M.M. Postan and H.J. Habakkuk. 250 L $$a2nd ed. We can make a parallel link between the two records

The LKR field in Cataloging 28 The PAR (parallel) link In record 67342, which is 2 nd edition, cataloger can catalog as follows LKR L $$a PAR $$b $$l USM01 $$n other edition available:1st edition $$m other edition available:2nd edition The subfield “n” points to the other record (not the record in which the LKR field is being cataloged

The LKR field in Cataloging 29 The PAR (parallel) link When web OPAC user views record 67348, which is 1 st edition, he will see as follows: Clicking the link will cause user to arrive to record (2 nd edition) When web OPAC user views record 67342, which is 2 nd edition, he will see as follows: Clicking the link will cause user to arrive to record (1 st edition)

The LKR field in Cataloging 30 The ITM (item) link ITM Links The ITM link creates a link between a bibliographic record and the items of another bibliographic record. The following is an example of an ITM link. In this example, Northern Albania (system number 67350) is the first volume of the series Albania (system number 67349). Central Albania (system number 67351) is the second volume of the series Albania. The items for all volumes are managed under the record Albania.

The LKR field in Cataloging 31 The ITM (item) link All items are entered via GUI in record Albania which is Bibliographic record number and Administrative record number Vol. 1Vol. 2 No items are entered for and 67351

The LKR field in Cataloging 32 The ITM (item) link Bibliographic record (Volume 1) contains the following LKR field: LKR L $$a ITM $$b (ADM record of the item) $$l USM50 (ADM library of the item) $$v 01 (Volume Enum. Level 1) Bibliographic record (Volume 2) contains the following LKR field: LKR L $$a ITM $$b (ADM record of the item) $$l USM50 (ADM library of the item) $$v 02 (Volume Enum. Level 1)

The LKR field in Cataloging 33 The ITM (item) link User goes to web and views Bibliographic record (Volume 1) and he gets the following link: Which brings the following item:

The LKR field in Cataloging 34 The ITM (item) link User goes to web and views Bibliographic record (Volume 2) and he gets the following link: Which brings the following item:

The LKR field in Cataloging 35 The ITM (item) link But… When user view the “main” record, 67349, where all of the items are entered, he will get the following link (to all items): Which brings all items:

The LKR field in Cataloging 36 The ANA (analytic) link Analytic Links ANA is a link between bibliographic records of different levels. When an analytic link is created the system generates UP / DWN links between the two records and an item link between the source record and the item that corresponds to it (according to vol.,part, year and pages) on the ADM record of the second record. For a list of all possible subfields for the ANA link see the “tag information” tab of the cataloging module

The LKR field in Cataloging 37 The ANA (analytic) link Scenario 1: We have the following records Studies in library science Vol. 1 of the series, titled “Developments in cataloging” Vol. 2 of the series, titled “Developments in acquisitions”

The LKR field in Cataloging 38 The ANA (analytic) link In record 67352, which is the “main” record, we add no LKR field, and we add items:

The LKR field in Cataloging 39 The ANA (analytic) link In record (Vol. 1) we add: LKR L $$a ANA $$b (number of the linked document record) $$l USM01 (bibliographic library) $$v 01 (vol. enum. Level of linked item) $$n Studies in library science (text for UP link) $$m Developments in cataloging (text for DWN link) And no items are added to this record

The LKR field in Cataloging 40 The ANA (analytic) link In record (Vol. 2) we add: LKR L $$a ANA $$b (number of the linked document record) $$l USM01 (bibliographic library) $$v 02 (vol. enum. Level of linked item) $$n Studies in library science (text for UP link) $$m Developments in acquisitions (text for DWN link) And no items are added to this record

The LKR field in Cataloging 41 The ANA (analytic) link Users views “main” record (67352) in web and sees link to all items And sees both items

The LKR field in Cataloging 42 The ANA (analytic) link Also in “main” record (67352) in web user sees links to both bibliographic records of the series: Clicking these links will cause user to arrive to each of the bibliographic records

The LKR field in Cataloging 43 The ANA (analytic) link In record and (Vol. 1 and Vol. 2) the user in web will have an UP link to the “main” record (67352)

The LKR field in Cataloging 44 The ANA (analytic) link Record (Vol. 1) will also have an item link which will bring only volume 1

The LKR field in Cataloging 45 The ANA (analytic) link Record (Vol. 2) will have an item link which will bring only volume 2

The LKR field in Cataloging 46 The ANA (analytic) link It is also possible to make an analytic link to a specific section of a bibliographic record. For example we have a record titled “Academic libraries: a collection of papers “. It is system number It includes many articles, two of them: Academic libraries in North America (pp 23-67) History of Academic Libraries (pp 68-97)

The LKR field in Cataloging 47 The ANA (analytic) link Bibliographic record is catalogued and one item entered (There are no volumes) Bibliographic record is cataloged as the first article from the previous slide “Academic libraries in North America” Bibliographic record is cataloged as the second article from the previous slide “History of Academic Libraries”

The LKR field in Cataloging 48 The ANA (analytic) link Bibliographic record is catalogued and one item entered (there are no volumes). Bibliographic record is cataloged as the first article from the previous slide “Academic libraries in North America”. Bibliographic record is cataloged as the second article from the previous slide “History of Academic Libraries”.

The LKR field in Cataloging 49 The ANA (analytic) link We enter one item for the “main” biblographic record, 67355, and no LKR field No volume

The LKR field in Cataloging 50 The ANA (analytic) link We enter no item for record 67356, and we add the following LKR field LKR L $$a ANA $$b (number of the linked document record) $$l USM01 (bibliographic library) $$k (pages) $$n Academic libraries: a collection of papers (text for UP link) $$m Academic libraries in North America (text for DWN link) It is customary to also put the pages of the article as part of the bibliographic record

The LKR field in Cataloging 51 The ANA (analytic) link We enter no item for record 67357, and we add the following LKR field LKR L $$a ANA $$b (number of the linked document record) $$l USM01 (bibliographic library) $$k (pages) $$n Academic libraries: a collection of papers (text for UP link) $$m History of Academic Libraries (text for DWN link) It is customary to also put the pages of the article as part of the bibliographic record

The LKR field in Cataloging 52 The ANA (analytic) link We enter web OPAC and view record It has a down link to both articles, and a link to the item.

The LKR field in Cataloging 53 The ANA (analytic) link We enter web OPAC and view record It has an up link to the main record, as well as the item of the main record

The LKR field in Cataloging 54 The ANA (analytic) link We enter web OPAC and view record It also has an up link to the main record, as well as the item of the main record
