All citations answer the same basic questions for the reader and include the same basic information for each source. Consider these questions:
- What type of information/writing is the work?
- Who wrote the work?
- Who published the work?
- When was it published?
- What is it called?
- Where can I find a copy?
It becomes confusing when some of those things are unclear. Once you have all of these answers, the rest of citation is just formatting.
