Thanks Steve! I have learned a lot from your suggestions!
Yes, I generate PDF in order to proofread. Also, I have used child documents to organize the book, previewing the child document is acceptable, mostly less than 10 seconds I think. Writing a shell to generate the PDF of the whole book is a good idea! here is my 2 cents of the shell script: #!/bin/sh lyx --export pdf4 mybook.lyx Finally, Lyx is really a great tool! I think it is impossible to finished the book without LyX within 4 months. Thanks to LyX teams!
