The author Bernie Folan:

“I carried out a similar project (collecting messages from librarians to
publishers) a couple of years ago and that data can be found here
https://drive.google.com/drive/folders/0B1bAnTSVq-LkcnVGUUtTVklMYlE as well as summarised in this
Insights article http://doi.org/10.1629/uksg.390
Please share within your organisation and encourage relevant departments and
senior management to read the messages so they can ensure they hear what
their partners and customers are saying, in a low-effort way.
Results of all research are made available openly and completely anonymously
with no mention of organisations or names. The objective of these research
projects has been to increase understanding and improve communication within
the scholarly communication environment, without any commercial objective. “
