Questions over controversial Homolka book

Julie Ourom writes \”A CBC Story.

If you aren\’t familiar with the story – Homolka and her then husband Paul Bernardo were convicted of the brutal sex slayings of two teenage girls back in the mid 90s. This is the second book Williams has written on the subject – and there\’s the usual controversy about capitalising on murders. An added dimension is that this one is only published in French, which will limit its audience.
How should libraries decide to add or not add this to their collections?\”

They say the book was written after 18-month correspondence with Homolka. This seems odd since part of her plea deal was that Homolka would not \”talk directly … or indirectly to the media for a book … or like endeavour.\”
