After reading about people's editing challenges ... sigh ...
We do a quarterly magazine which usually goes through three proofs, each of which has to be copyedited. We usually only get a one-day turnaround period ... but it's a small magazine (28 pages these days).
On the other hand, one of my long-term projects is reviewing and correcting a compendium of sections regarding various aspects of the design and construction industry as it pertains to the association I work for. They were "updated" a few years ago - mostly given a new look. The look is fine (except we've changed our logo and so they need to have new covers with the new logo). However, on going through, it looks like no one did a good copyedit on them. There are errors, places where it's not consistent with our style and, worst of all, there are references to figures which aren't in the current version. So I'm going to be reading several hundred pages of this and marking all the places that have to be corrected. Then I'll have to track down all the image files (they're in InDesign, so without the linked images, the quality would SUCK. In addition, we had a folder of stock images that were purchased years ago that was kept on our LAN that everybody could get to. I kept the files linked to those images in case some other poor soul had to work on them in the future. Well, someone's either deleted or moved the entire folder, and I can't find them. Luckily, I'd copied them all to my hard drive, so I just have to reset the links. A pain, but at least I can do it. People periodically bitch at me for not keeping everything on the LAN but, after this, and a few weeks ago when some absolutely vital files were deleted, I think I can say "told you so!"
