As per the restrictions of the above photos, the edited versions used here are also CC-BY-SA 2.0 (They're older, they'd likely be 4.0 these days, but no chances taken.)
Library Card gif drawings are all by me, and the materials used in the collage one are from photos I took. CC-BY-SA 4.0 upon them!
