When I get a release, it comes via .pdf, and I open it on an ipad with .pdf Expert. I know others who use Goodreader, etc. I use an apple pencil and the annotation tools in the .pdf program to highlight and underline, or write on the release, for reference in the airplane. I usually get my release one or two hours prior to report time, and I'll highlight anything relevant, including NOTAMs.
I suspect there are a variety of ways to do that, but this works for me. I keep company documents in the same program, so I can open anything relevant alongside the release. If there are maintenance deferrals, I can pull up the MEL and review them, and make any notes on the release, or references, etc. I can put the deice manual nearby, and relevant holdover charts, etc. Whatever I need, from the QRH to operations manuals, so it's available in one spot, quickly. If I have to reference that in a briefing, it's a tab away, already open, and also highlighted.
