[Mcls-print-storage] Allocation numbers

[Randy Dykhuis]

At the end of last week, we received data from SCS about several potential 
allocation schemes. Based on conversation during our last conference call, 
the preferences seemed to lean either toward an allocation distributed by 
collection size or by the proportions we agreed to when we thought we had 
735,000 candidates. Neither of these were perfect for everyone. This week 
I spoke individually to several participants and I think with a little 
rearranging, we can make this acceptable to everyone.

Barbara posted to the list that WMU would be happy with 110,000 titles on 
their discard list and when I talked to Pamela, she indicated that CMU 
would be willing to reduce their title list as well. Given that, here's 
where we are:

CMU: 37,000 titles
EMU: 67,145 titles
GVSU: 48,228 titles
MTU: 49,177 titles
SVSU: 52,673 titles
WMU: 110,000 titles
WSU: 169,844 titles

That should add up to 534,066 titles. In addition, you all have your lists 
of unique titles that will increase your possible withdrawals somewhat.

That leaves open Rick's question about how to use circulation data when 
creating the title lists. Should the lists be created without regard to 
where an item has circulated most? Or do we want to make sure that 
libraries that have the most circulations retain the titles (or conversely 
titles can be discarded in libraries that have zero circs). 

The ideal is that we have both predictable target numbers, such as shown 
above, and the titles on the discard lists are titles that are low use 
within each library. Since those are "competing objectives" as Rick says, 
my reading of the group is that you would rather have a predictable number 
of titles to discard and if that means that some titles on your shelves 
have zero circs you'll live with it. 

Is that an accurate assessment?
