A library (the public library, I think) isn’t seen but is mentioned in “Mother Hen-Pecked,” which I read in B&V Friends Jumbo Comics 261 (July 2018). It originally appeared in Betty 125 (July 2003).
The story is about Betty being kept up by birds chirping outside her window, but at one point Nancy drops by and reminds her about her entry for the library’s literary contest. Later we learn Betty did not win.
The story was written by Mike Pellowski, pencilled by Stan Goldberg, and inked by John Lowe. No colourist or letterer is given. It is copyright Archie Comics Publications.
