SPARQL > does have "ORDER BY" Because I need to count the number of results in an author-year group. If there are more than one, I then need to number them (using a letter). That's why "2000" does not have a suffix, but the two 1999s do. Likewise, I need to be able to replace the name with the three em-dashes for all but the first in the author group. So it helps to have the results sorted, but that's not enough, and it's a hassle if I then need to use XSLT (particularly 1.0) to do the additional processing. I'll add that grouping is a common problem issue on the XSLT list, and the new grouping support in XSLT 2.0 arguably the most useful new feature. Bruce
