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]

You probably have two \setupbibtex commands then, and that is currently not allowed.

The \setupbibtex command with the database= line wins, and if that one doesn't have a sort=, the default cont-no.bst will be used.

Best wishes, Taco

That is exactly right: I did have two \setupbibtex commands. Thanks!

it is good to know that my glass orb is still working :-)
