I'm currently writing up my Advanced Higher Biology report and am having trouble with some of the referencing. A few of the website I've used don't seem to have any indication as to when the articles on them were written. I don't know how to tackle this when it comes to referencing them in the text, or when coming to write the bibliography and was wondering if anyone could tell me what I should do?
Are you using a particular referencing style? If the publication date is just unavailable, omit it - but include a 'retrieved on' date in either case. Or, do you have any particular examples so we can dig around to see if we can find a publication date?
