Database Function - Haskell beginner needing help?

You just want to see if Book appears anywhere in the list. The simple way to look at this is via induction on the list of books. When there's one book loaned out, you want to compare that.

I'm assuming the database is a list of pairs of a person and a book that person has checked out.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
