I am desperate to have a paper published on a pre-publication server - I need it 'out there' for strategic reasons. I initially submitted it to SAGE Advance. There was no movement on having it approved, and the actual submission to a peer-reviewed Sage journal was desk-rejected. I withdrew the paper from Advance.
I am now planning to resubmit the paper for peer-review to a journal within an Elsevier Group (will do that tomorrow). They allow pre-publication and suggested the SSRN pre-publication service. Submitted the paper there last week and again, no movement on having it approved. Argh - any experiences on how long this might take?
