BibTeX, biblatex and biber ⇒ grouping citations in bibliography

[juliette]

Is there a way I get more than one reference grouped into the same enumeration in the bibliography ?

For example:

[1] article 1,
article 2.

[2] article 3,

[3] article 4,
article 5, and
article 6.

[4] article 7

Any suggestions would be greatly appreciated

Take a look at the micteplus package: this needs a suitably-designed .bst file but does the job very well. Or look at biblatex and the "reference sets" idea.
