What is a concise citation format for grant proposals given constraints on page counts? Many grant applications have page limits. They also often allow the writer to chose their preferred  format for references.

Thus, I was wondering:

What is a good concise referencing system that minimises the impact of references on page count?

Equally, perhaps there are other considerations beyond being concise, such as readability or highlighting that an author on the paper is also an investigator on the grant. Or perhaps it's better to stick to the reference format dominant in your discipline?

My initial thoughts were:


Use numbered references rather than author (date) format
Use first author and then et al for other authors
Use abbreviated journal names
Show only first page number
Depending on whether the grant proposal is computer read only or not there is a possibility of hiding the References list from your MS Word (or some other word processing applications). Once clicked on, the References will pop up as a full list.

If the references have to be visible at all times, then the shortest way of referencing would be to use in-text numbered references. And in the end of the research proposal, you could change the font size/style to accommodate "more" space for your full references.

There are many different referencing styles (some more academic than others) but if the goal is to use up as little space as possible for the references then short form full references would work for you. A short googling session yielded this result for a short form citation style: http://anton.cromba.ch/2016/02/07/a-minimal-citation-stylefor-grant-proposals/

Another way of referencing to consider could be the under-line references on each page. That font style can be changed more before it begins to clash with the overall "style" of the document, making it possible to create very space efficient references. Although space efficient, some extra space is needed to accommodate the paragraph styles and readability.
