Some of you might have noticed that IBM Knowledge Center does not include topic footers that provide a link to the information in PDF format. However, the DB2 for z/OS information is still available in PDF format.

From the product welcome page of each version in IBM KC (for example: http://www-01.ibm.com/support/knowledgecenter/SSEPEK_11.0.0/com.ibm.db2z11.doc/src/alltoc/db2z_11_prodhome.html), click the DB2 for z/OS PDF books link in the More information column. This link takes you to the DB2 for z/OS Product Documentation web page, where you can download the information in PDF format:
http://www-01.ibm.com/support/docview.wss?uid=swg27039165

Just like in the information center, the content in IBM KC is the most current.
