Re: Bibliography: 2 works by same author

Julian,

I think the two issues you are seeing may be related less to the individual bibliography commands than to the overall structure of the thesis.

For a 400-page document, ConTeXt’s structural context matters quite a lot. In particular, method=local may be something of a false friend here: what we really need to know is how the chapter scope is being established, where the bibliography rendering is placed in relation to the chapter boundaries, and how already-rendered entries are subsequently reused in the final bibliography.

Could you therefore show us the basic architecture you are using for the thesis? In particular:

- are you using a project/product/component structure, or a single main file?

- do you have a separate \environment file?

- how are chapters and sections actually opened and closed (\chapter, \startchapter...\stopchapter, etc.)?

- where exactly does \placebtxrendering[chapterlist][method=local] occur in relation to \stopchapter?

- and where are the btx definitions and renderings set up: in the environment, the product, or the main text?

We do not need the whole thesis, of course. The environment file (or the relevant parts of it), the main project/product skeleton, and the beginning/end of Chapters 1 and 2 should probably be enough.

My suspicion is that we need to separate three things more carefully: the structural scope of the chapter, the method by which references are collected/rendered, and whether entries already rendered in a chapter may be rendered again later in the final bibliography.

Once we see your document structure, it should also be possible to make a small two- or three-chapter test that reproduces exactly what you need:

Chapter 1 → local bibliography

Chapter 2 → local bibliography

…

End of thesis → complete bibliography containing everything.

That may also help explain why the Rogers example works correctly in the small MWE but not inside the full thesis.

Best wishes,

JP

Okay, JP, I solved the second problem (no chapter-level
bibliography for Chapter 2) easily enough: had forgotten to
include repeat=yes

\placebtxrendering
[chapterlist]
[method=local,
repeat=yes]

Now let's see if I can solve the first problem!

Hi Julian,

I tested your suggestion with the current LMTX APA
specification, and it turns out that the grouping logic is
already there.

With:

\cite[authoryear][beiser1987,beiser1990]

ConTeXt produces:

(Beiser, 1987, 1990)

whereas two different authors give:

(Beiser, 1987; Jacobi, 1785)

There is also the authoryears variant,
which produces the narrative form:

Beiser (1987, 1990)

So your suggestion is still very useful: this would
make a good additional example for the Garden page, since the
existing simple example does not show that APA already handles
repeated authors this way.

I attach the small MWE I used for the test.

Best, JP

It just occurs to me, looking at one of the
simple examples in https://wiki.contextgarden.net/Creating_a_bibliography_and_citing_sources ,
that it might be a good idea to include an example of two
works by the same author, as well as 2 works involving
different authors.

The example provided is

\cite
[authoryear]
[beiser1987,jacobi1785]

and that will produce, in-text, (Beiser, 1987;
Jacobi, 1785).

But let's say Beiser wrote a second work in 1990.

\cite
[authoryear]
[beiser1987,beiser1990]

will produce (Beiser, 1987; Beiser, 1990). It
might look better if we could get (Beiser, 1987, 1990). At
the moment I can't quite see how to get that.
