A colleague wishes to publish a pre-print as a "working paper" after the revised manuscript has gone through the peer review process and accepted for publication.
The rationale is that firstly, there is a long wait (over a year) until the manuscript is published by the journal; and, secondly, the publisher allows the author to deposit the pre-print at any time in an institutional repository.
My question is: Is a working paper series an "institutional repository"? Shouldn't the pre-print be submitted to the working paper series prior to peer review and journal acceptance?
