Re: Bibliography: 2 works by same author

JP, it is only the citation of an author with two or more works that 
remains unsolved. I soon realised, with the chapter-level bibliography, 
that I needed a repeat=yes, since many of the same works are being cited 
per chapter. So we can forget that issue.

In brief response to the info you request below with regard to the 
Rogers 1951 and Rogers 1961 references issue:

  * single main file
  * no separate environment file
  * \startchapter...\stopchapter
  * we can ignore the \placebtxrendering info per chapter, because it
    was my omission of the repeat=yes that was resulting in the
    non-appearance of the chapter-level bibliography. Now resolved.
  * btx definitions and renderings are in the preamble of the single file.
  * end of thesis calls in the entire bibliography

The obvious difference between your MWE and my setup is that you are 
calling in a buffer, whereas I am calling in a references.bib file with 
[main::rogers1951client,rogers1961person], so I wonder if the issue lies 
there. But one test I did was to create a buffer in the preamble for the 
rogers material (I left in the Jacobi example as well), and I adapted 
your MWE into a setup and called that setup at the first appearance of 
the double Rogers reference:

\start

\setups[bib]

Psychotherapy and counselling can become important places of such 
encounter. At their best, they offer a disciplined relationship in which 
experience may be approached with honesty, safety, challenge and 
compassion. Carl Rogers’ person-centred tradition emphasised empathy, 
congruence and unconditional positive regard 
\cite[authoryear][rogers1951client, rogers1961person]. These qualities 
do not suspend moral judgement or make dignity dependent upon approval. 
They describe a way of meeting another person in which something 
painful, shameful or destructive can be faced without the person being 
discarded.

\stop


But I still got the result as (Rogers 1961; Rogers 1951).

If it would help, since this reference occurs in Chapter One, I could 
give you a minimal version of the entire file with the full preamble 
(minus my buffer attempt), and first chapter with just the 'Rogers' 
paragraph in it. Let me know if that would be of assistance.
