National Geographic magazine with orange cover found

I found a National Geographic magazine with a bright orange cover this afternoon around 3:15pm near the downtown Lincoln library entrance on O Street. It's the June issue from a few years back, the spine is creased and the pages show light wear. Inside the front page there's a small sticker with the initials 'R.S.' and a bookmark sticking out between pages 42-43. It smells like coffee and it clearly mattered to someone. If this is yours, I can drop it at the library desk or we can meet at a nearby cafe; I just want to get it back to you.
