CDL: Questions about statistics harvesting methodology.

Questions about statistics harvesting methodology.
From: George Boston <george.boston_at_wmich.edu>

Good afternoon:

I have been asked to compile various statistics about print/electronic serials  and 
e-books for reporting to the ACRL by our Associate Dean for Collections. There are a 
number of documents that outline the basic parameters and methods at 
http://www.arl.org/stats/annualsurveys/arlstats/09statmail.shtml

But I was hoping I could get some advice about the best way to go about this.

There are a number of tools that we have that item counts, etc. These are:

- Serials Solution 360 Resource Manager
- Ex Libris SFX Link Resolver
- Voyager ILS (I can use Access/SQL to query the database)
- A Variety of manual/Excel files we keep during the year

After reading the ARL documents and looking at the various reports that the products above 
can produce, I've come up with a couple ways of going about collating the statistics. The 
problem is, depending on what system is used different results can occur.

I was wondering if others on the List are having the same dilemma and do you have a 
preferred methodology to deal with this problem?

Thank you,
