You can add query string or another argument to the link of article, for example:

node/[nid]/magazine or node/[nid]?ct=magazine
node/[nid]/book or node/[nid]?ct=book

After that you need to add visibility to the Book and Magazine block that appears in sidebar.

For Book block:

node/*/book

For Magazine block:

node/*/magazine

Hope it will help.

P.S. You can add argument or query string to the link of article through template_preprocess_node function by changing $vars['node_url'].
