HARVESTER TOOLS
Harvester tools make it easier to automatically gather COUNTER reports using the COUNTER API. They’re particularly useful if you need to collect COUNTER reports for a lot of platforms, or for lots of libraries. We’ve listed the tools we’re aware of on this page.
The friendly guide to working with COUNTER reports tells you more about harvesting. And remember, the tools in this list all work differently. If you want specific information about any of them, please get in touch with the relevent developers!

CC-PLUS
CC-PLUS is an open source software, community, and administrative tool set for usage statistics management designed to support libraries and consortia in data-driven decisions and effective stewardship of electronic resources. CC-PLUS was originally developed by eight international library consortia with ongoing development through the Kentucky Virtual Library.
CC-Plus is a standalone web-based Laravel application connected to a MySQL database and a web server. It allows for consortia to be managed within a host system, and requires COUNTER Release 5 reports. To try out the latest enhancements, request a demo space courtesy of the Kentucky Virtual Library (KYVL) or visit CC-PLUS on GitHub.
Celus
Developed by Big Dig Data for the Czech National Centre for Electronic Information Resources, Celus is an open-source solution for managing usage metrics. It is suitable for both single libraries and consortia. Celus processes COUNTER Release 5 and Release 5.1 reports as well as non-COUNTER data.
You can try the online demo for free at https://www.celus.net/ or download the source code from GitHub (https://github.com/techlib/celus).
Clarivate / Ex Libris Alma Analytics
Alma Analytics is the built-in business intelligence and reporting tool for the Ex Libris Alma library services platform.

EBSCO’s R5 Harvester Tool
Led by Oliver Pesch, the EBSCO Information Services team created this free tool and an associated easy-to-follow manual, which explains how to quickly get the Microsoft Access tool up and running and how to use it. The project is made available to the knowledge community under a Creative Commons Attribution Non-Commercial ShareAlike 3.0 Unported License.
While designed to allow small to medium-sized consortia to gather COUNTER reports for their affiliated libraries, single-site libraries can also use it.
System requirements: Microsoft Access 2016 or later, specifically working with Release 5-compliant COUNTER reports.
OCLC License Manager
WorldShare License Manager simplifies electronic resource management by consolidating the information you need to keep licenses active and to show your users exactly what resources they can access. License Manager stores, shares, manages and reports on all information and actions related to licensed resources in a central, searchable system.
You can find more details on the OCLC website (https://www.oclc.org/en/license-manager.html).
ReadMETRICS
Based on the existing open source ezPAARSE and ezMESURE tools, this is a new tool from the Inist-CNRS and Couperin consortia.
You can download the source code from GitHub (https://github.com/ezpaarse-project/readmetrics).
University of Prince Edward Island COUNTER Harvester
A harvester designed for Release 5.1 is now available from UPEI, and can be found on GitHub at https://github.com/Melissa-Belvadi-Library-Projects/C5.1_Harvester. The tool is designed for individual libraries rather than consortia, and it works entirely on a local desktop – no server required.
