I am applying for a postdoc position, and one of the required documents is a covering letter. Internet has models and templates and guides for such letters in rich supply. One thing, however, strikes me as strange: they normally contain the address. At first glance, maybe it is to be expected that a letter should have an address - but in this situation, I am uploading the file directly into an electronic application system, so it is utterly obvious what the document is, and who it should reach. I suppose almost all applications work in a similar way these days.
Firstly, I am curious if the address still serves any useful function. Or is it just a decorative element / historical artefact / etc.?
Secondly, should I actually include the address in an electronically submitted cover letter?
To clarify: I am asking about the address of the recipient of the application, not my own address. (While it is the case that I give my contact details in a separate form, I see how it could be convenient to duplicate this data.)
