Introduction
• Where or from whom does ProQuest obtain coverage data for each
title in our databases?
• In what format does ProQuest receive raw holdings data?
• What are the data elements in these source data? (For instance, are
enumeration and chronology both present in the title lists we receive
from the source, or does ProQuest supply the data? If ProQuest
supplies the data, how much research in involved, and how difficult is it
to provide holdings data for content coverage?
• How does ProQuest pass these coverage (holdings) data to Electronic
Resources Access and Management Services like Serials Solutions,
and in what format during data transfer?
• Is ProQuest implementing ONIX SOH standards in their coverage data
for ejournals? What are the issues in implementation, if any?
