Measuring the electronic library resources usage is increasingly crucial.
Prices are rising, and many economies around the world need to decide on what information resources to invest.
Based on the existence and quantity of use (downloads) that library managers can objectively be able to decide to renew or cancel a subscribed resource: from a unique journal subscription costing from USD 50 to USD 13000, or a database, ranging from USD 1000 to USD 40000.
Currently we find three general scenarios:
- Vendor does not indicate to the customer how many hits each title had. As it is not a rule, this lack of data happens, mainly on minor publishers…
- Vendor indicates how many hits each title had, with or without standard metric (ex Counter), and with no ability to the customer to audit that data.
- Customer captures the number of accesses by itself, using logs of its own proxy server – being the only channel of exit (the only IP authorized by the vendor is the proxy server IP).

4 different ways of measuring library eresource usage

“How does one measure library eresources usage? This is a question I’ve bumped into numerous times recently in the course of my work whether it be trying to do correlation studies between student success and electronic usage , choosing the right metric for the library dashboard or even more mundanely just evaluating a database for subscription.
My way of looking at it is two fold.
Firstly you can classify metric by the source, that is where you get the data from. Secondly you can classify by the type of usage metric.
For many electronic resource librarians, when you talk about electronic resource usage, the main source of such statistics would be via publishers, which usually but not always is COUNTER compliant.
But that’s not the only possible source. A secondary source of electronic resource usage perhaps less commonly used would be via the library’s own systems which typically means via Ezproxy (or perhaps openathen logs).
Of the usage statistics that you can derive from these two sources, I divide them into 2 main types of statistics, download based and non-download (session) based.”
