My manual is not looking so hot now. It’s been used and referenced many times - particularly during the 6 dev cycle (but the least said about that the better).
My copy of Real World Bryce 4 is now in two halves. The spine tore down where the color plates are when the book fell from a shelf. I grieved the tearing…
...But now, I’m kinda happy about it. Paperbacks tend to absorb water no matter what the environment, so a big manual turns into an even bigger one, sponging up atmospheric dampness. These days I only use the second half for reference, which has the plates and the complex sections, and occasionally use the first half for the history.
I don’t encourage ANYONE to destroy books deliberately, but I have to say: I had no intention to keep this book as a collector’s item, so the practicality of having a manual in two volumes has sincerely been a net positive experience for me.
