Hi Thomas, after thinking about the issue I wrote in my last message, I guess that implementing a general method with any counter could be better. I mean, implement three commands that could be applied to any counter: \getrangeinpage: first--last counter in page. \getfirstinpage: first counter in page. \getlastinpage: last counter in page. With first in page, as I wrote in my previous message, I don’t mean the first that happens in page, if the page doesn’t begin with it, but the last opened in previous page.. To be able to get the first in page and last in page is important in cases where works are divided in books and chapters. Information in headers should contain both. I think that the general method is a better approach (although I know that margin data aren’t counters [maybe this should be implemented in a different way]). I hope it helps, Pablo -- http://www.ousia.tk
