It is important that you try to find a date of publication rather than use (no date) in your reference. The currency of the information is a very important criterion for deciding whether a source is valid and whether you should use it in your academic work.
There are some tips you can try. To find the date of a webpage try looking at the page information in your browser for a 'created' or 'modified' date. Right click on the webpage and select the appropriate option. Please note: this information may not be available. For PDF documents, look at 'document properties' or find the webpage where the PDF is held.
