I would like to have a list of references sorted alphabetically by author surnames. My environment file has \setupbibtex[sort=author] and \setuppublications[sorttype=bbl] As I understand it, the \setupbibtex instruction is supposed to influence the .aux file. Specifically, the .aux file is supposed to include this line: \bibstyle{cont-au}. Then, bibtex will read the aux file and produce a .bbl file that is sorted alphabetically. Then ConTeXt's bib module will read the .bbl file and follow the sorting it finds in that file. However, after each ConTeXt run this line in the .aux file is set as \bibstyle{cont-no}. This happens in both Mk IV and Mk II, ConTeXt ver: 2008.08.05 18:47 I can change the relevant line in the aux file by hand, from \bibstyle {cont-no} to \bibstyle{cont-au}. This gives me the desired result when the file was processed by ConTeXt. The reference list is sorted alphabetically. In fact, subsequent ConTeXt runs using Mk IV (but not Mk II) produce an alphabetically sorted reference list, despite the changed line in the .aux file, provided bibtex is not run in the meantime. (Mk II runs it automatically but Mk IV doesn't ... I think) But this is not a fully stable situation. Suppose the bib file changes. Then I would run bibtex again. And then the alphabetical sorting is undone. Or, it was when I tested it. I don't know if this is a bug, a misunderstanding on my part, or a feature to be added later. If my memory is correct, this is not the way that Mk II used to behave. But in any event, It would be great to know of a more automatic way of handling this if one is available. Thank you! Michael
