Here are a couple more practical resources for help with writing skills, citing sources, and organizing research.
For citing sources and doing assignments: Here is a good website that provides lots of examples of formatting sources in APA style.
For managing research and citations: Programs such as Endnote or Zotero can store and organize your resources and format your citations for you. Check out A comparison of citation managers. Endnote software is free for McGill students and is supported by the library (meaning you can contact a librarian for help using the software if you need it).
