Easy set-up, intuitive interface

After two cycles of subscription renewals using CELUS to inform decision-making and report usage, we've really appreciated the easy set-up, the intuitive interface, the ease of use, and your responsiveness to questions and suggestions. The site looks good, which is helpful when reporting to management. Thanks, CELUS!

Permanently accessible, extremely flexible

CELUS brought us permanently-accessible, extremely flexible tools in terms of granularity, deeper views, selections, and so on for looking at each individual consortium member's data as well as a plethora of other possibilities for selections, groupings, comparisons, and beyond.
As CzechELib consortium leader, before CELUS, we had to rely on statistics supplied by e-resource providers, which were only raw data and which were often provided late.

Using the same tools, all individual consortium members can analyse their own statistical data and can compare  this with anonymized data from other consortium participants. The reaction to the introduction of CELUS was immediate, ranging from positive to enthusiastic.

Sustainable solution for harvesting, uploading, and reporting electronic resources usage data

We are pleased that we partnered with CELUS, and now we finally have a sustainable solution for harvesting, uploading, and reporting electronic resources usage data.
The training we received during the software's implementation was exceptional, and we continue to be impressed with their ongoing technical support.

Ensuring compatibility with future COUNTER releases

It goes without saying that since we aim to be the #1 tool for analyzing e-resources usage stats, we need to be active members of COUNTER’s Technical Advisory Group. We are participating in the development of the COUNTER Code of Practice itself, which makes us aware of any upcoming changes to the COUNTER format well in advance. Thanks to that, we can make sure CELUS will be always compatible with the latest COUNTER releases.

We are also very proud that we were asked by COUNTER to develop the new interactive Registry of COUNTER-compliant platforms.
The Registry is a great place for librarians to go to see reports supported by publishers plus required SUSHI information such as SUSHI credentials. CELUS integrates with the Registry and is automatically pre-populated with publisher SUSHI URLs. It can also tell you what parameters are required or what report types are available for a particular platform.
