I try to save paper these days by reviewing manuscripts via PDFs on my computer or my tablet. It also makes it easier to read stuff while traveling–both to read on a plane and to carry less paper around.
The biggest challenge in doing this is the habit/standard of people putting their tables/figures at the back of the document and having endnotes and not footnotes. I know most of the blame for this goes to journals which require such formatting, although that is changing (thanks Dan at ISQ). To be clear, the requirement is for submission of the final draft for many journals and not for the reviewing stage, but for whatever reason (path dependence, laziness, perceptions of what is required), people put heaps of relevant stuff at the back of a document. Please stop.
So, I am going to be annoying and ask my students/friends who give me stuff to read to format it the way I want it–in-text figures/tables and footnotes. Sorry, but the line is drawn here and no further.
And how about some page numbers, too?
