[Eril-l] Cost per use from COUNTER 5 Ebook reports

[Sarah Glasser]

You’re welcome. It took me a while to understand it all myself. That’s why I thought maybe my notes would help. Hopefully they did.

Cheers,
Sally

Thanks. I was looking at the Friendly Guide earlier, but that’s when I got confused. I’m getting a better understanding I think.

Hi Cindy,

Multiple sessions are counted, but if person A downloaded 5 chapters of Ebook X within one session, and person B downloaded 8 chapters within one session, it would count as 2 uses.

I am not sure how long a “session” lasts and what triggers a new session (perhaps log-out or idling non-use for some amount of minutes). Perhaps someone else can answer that.

Page 9 of the guide I sent earlier states that the Unique_title_request measures “usage of a book by a user. It does not measure the amount of usage, such as the number of chapter downloaded for viewing.”  If you want to measure amount of usage, Unique_item_request does this better, I believe.  However, the guide does go on to state (also on page 9) that the Unique_title_request metric “enables you to work out cost per usage across the two main types of platforms used” (platform that deliver books as separate chapters and platforms that deliver whole books only).

I am NOT an expert on this. I am only looking over my notes because I went through the same thing a while back and did my best to understand the difference so that we could make a decision as to how to move forward.

Sally

But none of the COUNTER 5 metrics can show that person A used Ebook X for 5 sessions, and person B used it over 8 different sessions, and count that as 2 uses, correct?

Thanks,
Cindy

Hi Cindy,

At my library we decided to use the metric Unique_Title_Request for e-books because it is more in line with a print book circulation (i.e. a use of the book regardless of whether the patron used one or ten chapters). I think the unique-item-requests counts chapter/section use (the “item” can be either an entire book or a chapter).  On page 10 of the Friendly COUNTER 5 guide for books (attached – not sure attachment will come through distribution list but sending to your email too), it suggests using the Unique_Title_Request for calculating cost per usage.

Hope this helps.

Best regards,
Sally

Hello – I am just realizing I may not be computing the unique titles used/requested for an ebook resource properly.

In the past, I have taken the number of titles mentioned in a TR report as the unique ebooks – what we would have had to purchase as firmorders if we wanted to replace the use we got from the subscription.

At first, I thought that that’s what Unique_Item_Requests represented when I started using COUNTER 5 Report Tool. Now that I read the definition, I’m not so sure.  I haven’t gone back in and compared the number of titles in my TR report to the Uniquet_Item_Requests in my PR reports, but I suspect they’re not the same. And if I had used Unique_Title_Requests, would that have been better? Can anyone shed light on this please?
