Page count is down as 576 but I strongly doubt it is that. The last actually numbered page is 547 with a few pages of maps afterwards which, if they were numbered too, would take it to 557. After that there's only a blank page and four pages advertising the authors other books, so even if they were factored in, it would still only take it to 567 pages max.
Worldcat shows 547. Advertisements should not be included. I think maps are okay, as they are content, but I'll enter 547. Another librarian might change it, if they think I'm wrong.
