Include location of your location of source

[nus-se-bot]

Please describe the problem
Currently, your Infinity Machine records sources but it makes more sense if you have an additional field to save where the source is located, especially if it's a website. It doesn't really make sense to collate a list of resources but not know where they are from.

Describe the improvement you'd like to suggest
Have an extra field that saves the location of the source (URL, journal name and volume no. etc)

will be settled once BiblioFields is ready.

@DoItTomorrow Will need your assistance in checking if this is possible once the bibilo fields are up and running.

seems to be solved with the new addition of bibliofields, closing.
