Suggested citation management tools


Note: CityU Library will end its subscription to ProQuest RefWorks and RefWorks (legacy) on August 31, 2019.


The Library now has a subscription for the citation management tool, EndNoteIt has a range of powerful features that make citation management more effective.

To get started with EndNote, and to find out how to move your references from RefWorks to EndNote, please refer to the Library's EndNote Research Guide.


(Library subscribed; available to CityU staff and students only)

ProQuest RefWorks, a new and improved version of the legacy RefWorks, is a cloud-based collaborative document and citation manager.  In addition to citation management, ProQuest RefWorks allows you to manage the full text of articles and share your work with other users. You can also cite references from your ProQuest RefWorks account in your Google Docs documents.

Try the new RefWorks!


    (Library subscribed; available to CityU staff and students only)

Use RefWorks, a citation manager, to help you store and manage the citations of your references, and generate bibliographies for your research papers.

This legacy version of RefWorks will be retired on 31 August in 2019. A new and improved version of RefWorks (ProQuest RefWorks) is available now.  Legacy RefWorks users may create a new ProQuest RefWorks account and try it out simply by clicking the link “Move to the newest version of RefWorks from ProQuest” at the top of the screen in their legacy RefWorks accounts.

Important notes on migration:

  • All contents in your legacy RefWorks account including references, folder structure, attachements and custome styles will be automatically copied to your new ProQuest RefWorks account.
  • Users can keep and use both their legacy and new RefWorks accounts in parallel before legacy RefWorks retires.
  • Migration from legacy to new RefWorks can occur multiple times (new RefWorks will only import new references from legacy on subsequent imports).  However it is a one-way migration, meaning reference changes will not migrate back to legacy from new RefWorks.
