I would like to create a course that is modularised into topics, so that I can deliver it in bite-size chunks. This also means the topics may use common resources. I have been using pages to create some content, but have realised it is not easy to share these pages between courses nor within the same course. I'd like my courses to be mobile compatible hence my preference for HTML rather than downloadable files.

I considered: 

• Repositories - but these seem like more to do with files than HTML pages (so not easily updated within Moodle)?
  
• Autolinking - but this is only for glossary and activities, not resources
  
• Sharing cart - but this seems to duplicate the resource, which would mean updating all instances of the duplicated resource
  
• Links - this means giving the resource a different name, and having an necessary two step click process, I am concerned about URL changes and portability as the links might not apply in a new environment.

I am wondering if I should change my tactic of creating separate courses for my modularised topics and perhaps create lessons, though it seems having pages within the same course will not solve my issue? 

Any suggestions appreciated.
