I am creating an index for a non-fiction book, and I am using LibreOffice writer. It has functions that help generate an index. When it does so, some of my entries look like this:
stuff..... 9, 12pp., 20, 27, 134p.
What I can't figure out is what these "p." and "pp." designations stand for. I think it has to do with the entry being on contiguous pages or not, but by looking through my index and their entries, sometimes more than one page is involved, sometimes not... it's not easy to discern the pattern from what is happening in my book.
Also, of course I looked around the web, and I've seen "pp" used when designating sequences of pages, but in that case the beginning and end are identified, something like "pp18~20". I've also seen "pg" mentioned as being a single page, but I'm not clear on why you would need that, and if it's different from a single "p".
What does "pp." mean, and what does "p." mean?
Note that this is not a technical question about whether or nor I can or can make LibreOffice create or not create these "pp." and "p." designations. First I want to know what they mean from the point of view of creating an index in general. Once I understand what they are, then I'll work out whether or not it's worth dealing with the software.
