I think it would be useful to cite:

• NIST’s report on the economic impact of TREC [1] as motivation for why software citation is important
• "Assessing the impact of software on science: A bootstrapped learning of software entities in full-text papers" [2] - it has some nice stats on how much software is found in PLOS.. not OA :-( unfortunately
