I disagree based on my decade+ experience working with Federal employees. I would guess that 50% of GS-13 to GS-15 (heck even SES) are mostly incompetent, 40% get the basic minimum of their job complete, and the final 10% shoulder most of the work accomplished. I have come across many GS staff given busy work roles so they are "out of the way" of leadership's objectives. :edit: For folks downvoting me, this is just my personal opinion based on my experience working within IT and cybersecurity. My observations can easily be (and may actually be) untrue elsewhere (as noted by replies to my comment). Early in my career, I was a GS-13 myself.
Libby and Overdrive are the same thing with different skins. Neither app is good but Overdrive is simpler (IMO) for reserving books and downloading them, so I stuck with Overdrive.
