Wow, man. That's exactly what I've been compiling for my own con-world over the last several years, though yours looks much prettier.

here's a link to my own OP wiki to give you an idea of what you can do at the portal.
so, a bit of an update on the 'Hinterlands' map (the word hinterlands being a bit of a misnomer here as it covers an area far larger than that of the empire that created the map itself...). I say bit of an update, but i basically wen't back to the drawing board and started over as i wasn't happy with the layout of the previous version (largely the fact that i was repeating so many regions in the north-west of the map from the previous map. so i repositioned the continents and came up with this:
Nice encyclopedia thing. I'm like you in that I prefer the look of a book but what can you do. I think your effort to get the book feel on your finished pages is quite nice. Now you just need to find a booklet app or something that allows you to turn pages like a book.
That's… quite a lot of pixels. 300 dpi is rather excessive for even a standard poster print, and that's large even by poster standards. Are you aiming merely to give yourself a lot of flexibility for the future, or is your intended presentation format a huge poster that viewers can view at less than arm's length?
Not that I object to lots of pixels, but it seems like it would be cumbersome to work with. Anyway, you might get better results from your rescale if you use a different filter. If you're using Photoshop, go to Edit > Preferences > General (Ctrl-K). In the Image Interpolation drop-down, try Bicubic Sharper. Recent versions of Photoshop conveniently give you hints as to which filter is best for certain tasks. It's usually best to leave it at Bicubic for general work, but if you're getting artifacts from a rescale, it can be worthwhile to try the others. Just don't forget to change it back when you're done.
