Subject: [SERIALST] Comparing tiltes in databases

Helo
I'm not sure if this question has already been adddressed by this group.
 
I have been asked to compare journal titles in our 70 databases for overlap. Assuming that each databases has a conservative guess of 5,000 journal titles would mean there are 350,000 journal titles to compare.
 
Does anyone have any suggestions on how I would go about performing this request?
 
Thanks in advance,
 
Susan Oxford
