Perhaps this should not be a new topic, but having found the previous topic I started on a similar subject in the archives I could not find a way to continue that topic, so here we are. Thanks to Brian and Tim for answers to my first query on the pros and cons of FM books. I've taken your suggestion, brian, and bought a copy of FM Classroom in a Book. 
My current question relates to conversion of an FM book to PDF. Are all book files converted to a single PDF, or is it possible to select particular files that should be part of the same PDF and others in a separate PDF? The reason for asking is that I have a number of maps and a glossary. Ideally I'd like to have them as pop-ups, but I don't think that is possible from a PDF (please correct me if I'm wrong), and the next best option seems to be to create the maps as a separate PDF file to the main PDF and open the maps as a new window (similarly for the glossary file). If I can't prevent them all from becoming 1 PDF then I'll need to plan to keep the map and glossary files out of the main book from the start. Hope that is reasonably clear <G>, 
�and thanks in advance for any ideas or advice
