Hi, I am not sure if some has had this problem before, but I encountered difficulties when using the endnotes package with lyx and did not find any answers on the LyX WiKi site describing how to use Jurabib with LyX.
The core problem was that although I had inserted \usepackage{endnotes} in the preamble, references inserted as footnotes still appeared as footnotes in the final output and an ERT containing \theendnotes resulted in errors. After studying both the Jurabib documentation and TLC2e (both giving no direct answer to this question either), I tried out inserting \renewcommand\footnote{\endnote} into the preamble - and now everything works. I think this issue should also be described in the LyX WiKi. Or am I missing something? Kind regards, Kimmo
