The documentation has been moved from the old pdf manual based bookshelf to the new DocOps wiki platform. In DocOps the pages are updated continuously as changes are required. There is no longer a bookshelf with separate pdf books as there was in the past.
If you click on the PDF icon on the main page it will create one pdf file with all the CA Datacom pages.
If you first click on a topic and then click on PDF it will create a pdf with all the pages related to that topic. This will give you something similar to the old pdf books.
For example if you click on Getting Started and click on PDF you will get a pdf with all the pages related to this topic.
