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

[Melissa Belvadi]

Another reason to use unique_title_requests compared with unique_item_requests for ebooks is that some providers only allow the user download one chapter at a time, but others allow both individual chapter downloads and also the entire ebook as a single PDF. There has been a lot of debate about whether the provider should count that entire ebook download as just 1 item requested, or count the number of chapters and count that many. At this point, you can't know vendor by vendor which way they are handling that.  But you can count on unique_title_request to count it all as 1 use for sure.

Librarians have been debating the issue of print-circulation equivalency to ANY ebook metrics pretty much since ebooks became popular.
Unique_title_requests have been COP5's way of addressing at least some of the objections to drawing those equivalencies.
But I know some anti-ebook librarians are going to refuse to accept ANY metric.

In my experience, the numbers for unique title requests and total requests are very similar – unless they aren’t. If you look at the numbers month by month, they mostly correlate and then sometimes there will be one month where there’s WAY more in total, and I’m not quite sure why.



I think Cynthia is correct, that the way it counts unique uses is not precise enough to make that much difference. I don’t think unique would be like a print circulation – I wouldn’t compare those numbers directly for sure. I have usually gone with total, myself, assuming a use is a use, whether it’s by the same person or not.



I think this is one of the things that makes COUNTER 5 so confusing – instead of clearing up confusion, the additional data just creates more questions and makes me not sure what to think.



I think as long as you’re consistent in which count you use, and don’t try to compare the numbers to COUNTER 4, then you’re doing the best you can.



I like to see how many titles are used, myself, and maybe how many months they got used. Neither of those are official COUNTER numbers, but I think they give me a better picture of how the ebooks are doing (compared to other ebooks) and how likely they are to be used again than how many item requests one book gets in one year, given how weird that number can be.

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

EXTERNAL MESSAGE

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?
