We haven't had any concern about the "current issue" date ranges.  Ours
cover from 1-5 years (i.e., all computer science journals are kept 5 years
on the current shelves with no archives).  We keep all our information in
an Excel spreadsheet that shows the retention, use, and prices (use and
prices for 5 years).  We also separate our use into current, bound, mf,
and electronic.  We have less than 900 current subscriptions.

We follow a similar procedure as Dana as far as scanning everything that
gets reshelved, item records for bound volumes in Innovative, etc.

Couple of hangups we have found and not gotten past yet:

Some of our librarians are concerned about the date range of "current
issues"; as we all know, depending on your binding schedule, there could
be anywhere from two weeks to two years of "current issues" on the shelf
at any given time.  The average is likely around one year but I haven't
verified this.  Dana, can I ask you what assumptions you make regarding
the time span of current issues?  Some librarians feel that they need more
precise usage data for current issues (specifically in
chemistry/physics/engineering), and we are not sure how to obtain this
conveniently in an automated way w/out barcoding every issue.

Dana, could you also tell us the size of your collection and the software
you are using to manipulate the data?

We are exploring various cost per use methodologies too.  Is anyone doing
anything experimental?  How about journal impact factors, half-life, etc.?
Use of eletronic versions of titles?  Any preferred approaches, experience
to share out there?
