Re: Daily Link Maintenance

Mieko,

I'm not sure this is true.  I run Daily Link Maintenance Monday through 
Friday after all catalogers leave for the day.  There are hundreds of 
items in the link maintenance file by morning.  On Monday morning there 
are thousands of items in this file even though there has been no 
cataloging activity over the weekend.  I have always assumed that records 
that are checked out and/or checked in and maybe even placed on hold are 
going into the file.  Not very efficient.

If Betsy Graham says this isn't so, maybe there's a bug in the program or 
some parameter is not set correctly on our system.
