In the Library Browser, I am trying to access the problems in the National Problem Library.
For example, doing a search for problems in the National Problem Library, I click on:
Subject: Calculus – single variable
Chapter: Differentiation
Section: Definition of the derivative
Webwork says that “There are 94 matching WeBWorK problem files”
However, only 28 problems are shown. (The same type of misinformation happens with other searches.)
