You haven't told us how it's supposed to be writing it out to file. One way to do it would be to build your data structure then output it to file with Data::Dumper and then recreate the struture in you file with require 'file'. This is a simple way of storing data from a hash. Alternativly have a look at a database such as DBD::CSV which is a backend for DBI allowing you to use a plain text file like a full database.

For the code you are showing you may want to eithier display a list of books ie. print(join "\n",keys %borrowed_DB) or use inexact matching, maybe grepping the keys for a book title that contains the specifed text.
