Other people's copyright material in your research
Employing good copyright management practices will ensure you have the permissions necessary to publish other people's copyright material that is included in your research. If you have not obtained such permissions you need to consider removing the third party content or delay publication until you have all necessary permissions.
Publishing agreements and licences
When publishing your research such as in a journal you are likely to enter into a publishing agreement. Quite often you are required to assign (i.e. transfer) copyright in the work to the publisher. Assigning copyright (whole or in part) to a publisher can limit your ability to deal with the work later on. Therefore you should ensure that no future contractual or other obligation inhibits your ability to publish.
If you are not sure about what rights you will retain under a publishing agreement seek clarification from the publisher.
End user licence (How can other people use your research publication?)
It is good practice to inform end users of your research publication and what they can do with it. (e.g. download or print for personal use; adapt the work for educational or non-commercial uses etc.)
