Creating local and multiple bibliographies

1. Creating local and multiple bibliographies

The previous guide distinguished the main layers of the bibliography system:

• bibliographic sources;
• datasets;
• specifications;
• citation alternatives;
• renderings;
• bibliography scope;
• repeated rendering;
• sorting rules;
• placement.

This guide applies those distinctions to documents that require more than one bibliography.

Typical editorial needs include:

• a bibliography at the end of each chapter;
• a final bibliography at the end of the document;
• several lists generated from one dataset;
• separate collections of primary and secondary literature;
• chapter-level lists associated with more than one dataset.

By the end of the guide, you should be able to:

• distinguish the roles of method , criterium ,

 and repeat;

• create chapter bibliographies and a final bibliography;
• define several renderings for one dataset;
• decide when several datasets are useful;
• combine structural scope with bibliographic classification;
• understand why one record may appear in several lists without being

 duplicated in the data.

2. Bibliography scope: method, criterium, and repeat

Chapter-level and final bibliographies depend on several different settings.

The three most important are:

method
criterium
repeat

They should not be treated as synonyms.

2.1. The role of method

The method setting controls how a rendering uses the bibliography reference state available to it.

Common values include:

Method	General role
method=dataset	Uses records from the dataset itself, including records that may not have been cited.
method=global	Uses bibliography references registered globally in the document.
method=local	Uses a local rendering context rather than the global rendering state.

The value local should not automatically be interpreted as “the current chapter”.

Structural scope is controlled separately.

2.2. Structural scope with criterium

The setting criterium determines the structural or reference scope requested for a bibliography rendering.

For example:

\placebtxrendering
  [chapterlist]
  [criterium=chapter]

restricts the rendering to the current chapter scope.

This distinction is essential:

method     = rendering/reference-state behaviour
criterium  = structural or reference scope

A bibliography placed at the end of a chapter is therefore not a chapter bibliography merely because of its physical position.

Its structural scope should be expressed explicitly.

2.3. Reusing records with repeat

A record may already have appeared in an earlier bibliography rendering.

The option:

repeat=yes

allows such a record to be rendered again.

This is particularly important when:

• the same work is cited in several chapters;
• chapter bibliographies are followed by a final bibliography;
• several different renderings intentionally reuse the same record.

Thus:

method     -> how the rendering uses bibliography state
criterium  -> which structural scope is requested
repeat     -> whether already rendered records may appear again

2.4. A common chapter-level pattern

A chapter bibliography may therefore use:

\placebtxrendering
  [chapterlist]
  [method=global,
   criterium=chapter,
   repeat=yes]

The three settings should be read separately:

• method=global uses bibliography references registered globally;
• criterium=chapter restricts the rendering to the current chapter;
• repeat=yes allows records already rendered elsewhere to appear again.

A final bibliography may then use:

\placebtxrendering
  [finallist]
  [method=global,
   repeat=yes]

3. One dataset, several renderings

A dataset contains records.

A rendering defines a particular bibliography list constructed from those records.

Several renderings may therefore use the same dataset for different editorial purposes.

For example:

\definebtxrendering
  [chapterlist]
  [apa]
  [dataset=main,
   sorttype=authoryear]

\definebtxrendering
  [finallist]
  [apa]
  [dataset=main,
   sorttype=authoryear]

The two renderings use the same records and specification, but they have different editorial roles.

The chapter rendering can be placed with:

\placebtxrendering
  [chapterlist]
  [method=global,
   criterium=chapter,
   repeat=yes]

The final rendering can be placed with:

\placebtxrendering
  [finallist]
  [method=global,
   repeat=yes]

3.1. Several renderings are several views

One dataset may feed:

• a chapter bibliography;
• a final bibliography;
• a complete catalogue;
• a list in dataset order;
• a list in author–year order;
• lists with different headings or typographical settings.

The renderings do not contain separate copies of the records.

3.2. The same record may appear in several lists

Suppose a work is cited in Chapter 1.

It may appear:

• in the bibliography at the end of Chapter 1;
• again in the final bibliography.

This is not a duplicated bibliographic record.

It is one record rendered in two editorial contexts.

4. MWE: chapter bibliographies and a final bibliography

The following self-contained example uses one dataset and two renderings.

The intended result is:

• the first chapter bibliography contains Jacobi and Beiser;
• the second chapter bibliography contains Ameriks;
• the final bibliography contains all three records.

Element	Role
main	Dataset containing all records
chapterlist	Rendering used for chapter bibliographies
finallist	Rendering used for the final bibliography
method=global	Uses bibliography references registered globally in the document
criterium=chapter	Restricts the chapter rendering to the current chapter scope
repeat=yes	Permits records already rendered in an earlier list to appear again

5. When to use several datasets

Several datasets may be useful when the records belong to stable and meaningfully distinct editorial collections.

Examples include:

• primary texts and secondary literature;
• archival sources and printed scholarship;
• works cited by the historical author and works cited by the editor;
• bibliographic collections belonging to independent parts of a project;
• editions and translations treated as independent editorial collections.

For example:

\usebtxdataset
  [primary]
  [primary-sources.bib]

\usebtxdataset
  [secondary]
  [secondary-literature.bib]

References can then be qualified explicitly:

\cite
  [authoryear]
  [primary::hegel1820]

and:

\cite
  [authoryear]
  [secondary::beiser1987]

5.1. Several datasets are not always necessary

Primary and secondary literature can be separated into two datasets, but this is an editorial choice rather than a universal rule.

A project may instead use:

• one dataset with several renderings;
• one dataset with project-specific classifications;
• several source files loaded into one dataset;
• several datasets when the collections must remain explicitly distinct.

The architecture should follow the needs of the project.

6. Two datasets and two independent dimensions

When several datasets are used, two editorial dimensions operate together:

1. the dataset identifies the bibliographic collection;
2. criterium identifies the structural scope requested for a rendering.

The rendering method remains a separate setting.

For example:

\definebtxrendering
  [localprimary]
  [apa]
  [dataset=primary,
   sorttype=authoryear]

\definebtxrendering
  [localsecondary]
  [apa]
  [dataset=secondary,
   sorttype=authoryear]

At the end of a chapter:

\subject{Primary sources used in this chapter}

\placebtxrendering
  [localprimary]
  [method=global,
   criterium=chapter,
   repeat=yes]

and:

\subject{Secondary literature used in this chapter}

\placebtxrendering
  [localsecondary]
  [method=global,
   criterium=chapter,
   repeat=yes]

The first rendering asks, in editorial terms:

Which records from the primary dataset belong to the current chapter scope?

The second asks:

Which records from the secondary dataset belong to the current chapter scope?

The dataset and the chapter criterion answer different questions:

dataset    -> which collection?
criterium  -> which chapter or structural scope?

7. MWE: chapter bibliographies from two datasets

The following example defines two datasets and two chapter-scoped renderings.

• 

The first list contains the record used from primary in the current chapter.

The second list contains the record used from secondary in the same chapter.

The unused records remain available in their datasets but do not appear in these chapter-scoped lists.

8. Choosing the right architecture

Editorial requirement	Recommended architecture
One final bibliography	One dataset and one rendering placed with method=global
One bibliography at the end of each chapter	One dataset and one rendering placed with method=global and criterium=chapter
Chapter bibliographies and a final bibliography	One dataset with chapter and final renderings; use criterium=chapter for chapter lists and repeat=yes where records must reappear
Complete catalogue and cited bibliography	One dataset with one rendering using method=dataset and another using method=global
The same collection in different orders or formats	Several renderings from one dataset
Primary and secondary collections that must remain structurally distinct	Separate datasets and separate renderings
Editions and translations treated as independent collections	Separate datasets may be appropriate
Chapter-level primary and secondary bibliographies	Two datasets, two renderings, and criterium=chapter

9. Common problems

9.1. The wrong rendering scope is used

The setting:

method=dataset

can include records from the complete dataset, whether cited or not.

A chapter bibliography normally requires an explicit chapter criterion:

criterium=chapter

Do not use method=local as a synonym for “current chapter”.

9.2. A rendering is associated with the wrong dataset

A rendering such as:

\definebtxrendering
  [secondarylist]
  [apa]
  [dataset=primary]

cannot render records stored only in secondary.

Check the dataset attached to every rendering.

9.3. Several renderings are confused with several datasets

Several renderings provide several views.

Several datasets provide several collections.

Do not duplicate bibliographic data merely because the document contains several bibliography headings.

9.4. A record appears in both a chapter and a final bibliography

This is normally intentional.

A chapter-scoped rendering and a final document-wide rendering may both use the same bibliographic record.

The record remains stored only once in the dataset.

9.5. A chapter bibliography contains unexpected records

Check:

• whether criterium=chapter is used;
• whether the rendering is placed inside the intended chapter scope;
• whether the citations belong to the expected dataset;
• whether the records were registered in the intended structural context;
• whether method=dataset is unintentionally including uncited records.

9.6. A final bibliography omits a record shown in a chapter bibliography

Check:

• whether the final rendering uses the expected dataset;
• whether it uses method=global when a bibliography of used records is intended;
• whether repeat=yes is needed;
• whether the record was actually cited or otherwise registered;
• whether the document has been processed again after structural changes.

9.7. A record appears in one chapter but not another

If the same record is cited in several chapters and chapter bibliographies are placed repeatedly, check whether:

repeat=yes

is required.

The structural criterion and the repeat policy answer different questions:

criterium=chapter  -> does the record belong to this chapter scope?
repeat=yes         -> may it be rendered again?

10. A practical diagnostic table

Symptom	Check first
A chapter bibliography is empty	Rendering dataset, qualified keys, chapter placement, and criterium=chapter
A final bibliography is empty	Rendering dataset, registered citations, and method=global
An uncited record appears	Whether method=dataset was used
A primary source appears in the secondary list	Dataset loading and rendering association
A record appears in two lists	Whether two renderings intentionally include it
A record shown in a chapter bibliography is missing from the final bibliography	Final rendering scope and repeat=yes
A list contains records from another structural unit	Placement context and criterium
A record cited in two chapters appears only in the first bibliography	repeat

11. What you have learned

This guide has shown how datasets, renderings, structural scope, and repeated rendering combine to produce chapter-level and multiple bibliographies.

Question	Mechanism
Which collection contains the record?	Dataset
Which bibliography list is being produced?	Rendering
Which bibliography reference state is used?	method
Which structural or reference scope is requested?	criterium
Should every stored record be available to the rendering?	method=dataset
May a record already shown in another list appear again?	repeat=yes

The main principles are:

• one dataset can feed several renderings;
• several renderings provide several views of the same records;
• several datasets may represent stable and distinct editorial collections;
• chapter-level and final bibliographies can render the same record without

 duplicating it in the data;

• the dataset and criterium answer different editorial questions:

 the dataset identifies the collection, while the criterion identifies the
 requested structural scope;

• repeat controls whether an already rendered record may be used

 again.

The essential distinction is:

dataset    -> which collection?
method     -> which rendering/reference state?
criterium  -> which structural scope?
repeat     -> may an already rendered record appear again?
