As I understand it, the reason to use templates is so that users can alter the relevant Koha display. I am however finding it very difficult to see how to make one particular change in the current version. As I have said, the library I am concerned with is a professional library, ie similar to a reference library save that the books can be borrowed. The edition of a book is in most cases relevant since the user may well want an old edition rather than the current one - or vice versa ... (I have one old book where the 3rd edition is in my view much better than the 4th which was abbreviated because of post-war paper shortages.) Alternatively he may need to ensure that he has the latest edition. So I would like eg http://radchams.co.uk/cgi-bin/koha/opac-detail.pl?bib=123 to include a line such as Edition: 17th Ed. I can see how to alter opac-detail.tmpl using something like <!-- TMPL_IF name="edition_statement" --> ...<!-- /TEMPL_IF --> but I cannot see where or how I would add the appropriate $template->param() command (and what the command would be to get what appears to be 250a). The koha docs are in the main excellent but I cannot see how to do this. Roger -- Roger Horne roger@hrothgar.co.uk http://hrothgar.co.uk/YAWS/
