<div>I agree that in general ILL isn't great
for predicting future usage, partly because the number of requests
for any individual journal tends to be small and given to
fluctuation--we've actually had much better luck with judicious
use of turnaway data, though in all cases it's best to look at a
minimum of 2-3 years. At our undergraduate-masters institution,
we often see usage spikes that we strongly suspect are
attributable to one person's capstone project, so we like to look
at average usage over time.<br>
<br>
That said, there can still be useful information to be found in
the ILL stats. In our case we found a handful of titles that were
generating a disproportionate number of requests (and costing a
bundle in copyright clearance fees). Subscriptions to those
titles have been a runaway success, generating usage numbers many
times the number of requests. I would expect such finds to be
fairly rare, but it's wise to keep an eye on the ILL anyway
because it can surface emerging research needs.<br>
<br>
Regarding researching ILL vs subscription usage, I imagine it
would be difficult to compile a large enough data set. Cancelling
a big deal provides plenty of evidence of subsequent ILL usage
(with the caveat that retained perpetual access may result in very
small amounts inaccessible content in the first year), but
subscribing to titles en masse based on ILL evidence is probably
less common. In our case, we've used a back-of-the-envelope
estimate that 15% to 25% of subscription will translate to ILL,
depending on the journal and its primary users, and saw roughly
the inverse of this when we subscribed to our "frequent flyers."
That is, where we saw approximately 1 ILL request where there had
been 5 subscription uses, we now saw 5 subscription uses for every
1 ILL request we had before for those titles. However, we
cherry-picked the obvious winners for subscription and our data
set is miniscule, so I'd hesitate to extrapolate beyond cases
where ILL demand is above average and ongoing.<br>
<br>
In terms of turnaway data, we used it to inform purchase of
several backfile packages and saw that while it was not
necessarily predictive of usage for any one <i>individual </i>title,
<i>in aggregate</i> turnaways from backfile content translated
well to usage of that same content once subscribed. In this case,
we were able to study a large number of titles and multiple years
of data. Backfile usage may also be different from frontfile
usage. As turnaway data becomes more available with widespread
adoption of COUNTER 4, perhaps we'll see more research in this
direction.<span class=""><br>

<p class="MsoNormal"><span>This article lends
credence to my hunch that ILL data has limited validity as
indicator of future use. First, you need to look at the age
of the items requested at the time of the requests – are
they requesting older articles or the latest articles?
Secondly, you need to examine trends in usage over time –
has there been a steady direction of the number of
requests? Finally, examine the number of individuals making
these requests. Do all of the requests for this title come
from 1 or 2 people?<u></u><u></u></span></p>
