I want to print selected pages from a Microchip PIC data sheet which is in .pdf format, with 436 pages, so printing it all out would use up an awful lot of paper and ink. I would like to open it with LibreOffice and use that to remove most of the pages from the copy. With, in Linux, "bookbinder" software I would convert the result into two other .pdf files, backs and fronts of the sheets, which I can then print out, with four A5 sized pages per A4 sheet, ending up with a nice little booklet with just the information I want to refer to.

I have no intention of doing any other editing to affect the original document, nor will I be attempting to sell any of it or make money from it, so this seems an innocent wish. Please is there a way to do it?

Thank you @fvu for your suggestions. In the meantime I have found a solution that works for me. I simply print the locked file to another .pdf file, using the printer software, and the destination file is identical but unlocked. I can open it in LibreOffice Writer, and I could edit it if I wished.

To do what I really want, that is to extract some of the data, I can set up the print job to include just the pages I need, so the file size can be kept to a minimum. No need to involve LibreOffice or any other software for this task.

The process is simple, and probably no more complex than any other method would be.
