ABSTRACT:
A reference list for use with a book comprises a plurality of information bearing lines which are initially masked and are progressively unmasked as the book is read. This provides a progressive index which may in the case of a narrative provide a list of characters as a memory aid or in the case of a teaching book it may provide the answers only to the questions previously attempted.
