Why was there no side by side comparison of EBSCO's Academic Search/ Business Source products and ProQuest Central

At the 2015 renewal, pricing and trial of ProQuest Central was provided to partner libraries. At that time, the vast majority of libraries showed no interest in moving to ProQuest Central. At the time of the common suite investigation in 2017, there had been no change in interest levels. During conversations with partners, an almost unanimous desire for Academic Search Premier, Business Source Premier, and at leas one Complete was expressed. Hearing limited interest in ProQuest's competing product from stakeholders, a side by side comparison was not undertaken.
