What is the problem?

PSI has been working with publishers for many years, helping them to detect, investigate and prosecute subscription fraud. In that time we have won and settled many cases recovering substantial damages for our publisher clients. In recent times we have turned our attention to the IP ranges publishers hold to authenticate their institutional customers; on average these are incorrect in 58% of cases; either by human error or maliciously. Inaccurate IP data can be costly to publishers for a number of reasons:

Unlicensed access – too broad an IP range can facilitate institutions piggy-backing on the licences of others and thus gaining free access.

Inaccurate usage statistics – wrongly entered, duplicated or over-lapping IP ranges can cause accesses and/or downloads to be counted multiple times. Too narrow an IP range can mean institutions have insufficient access and lead to increased turn-aways.

How does the IP Registry help Open Access Publishers?

OA publishers have difficulty in gauging impact of content when they cannot measure usage nor identify consumers.

By linking log files to the IP Registry publishers can understand where access is coming from, better measure impact and target future marketing activity.

How it works

The IP Registry currently holds around 1.5 billion validated IP addresses from over 60,000 content licensing organisations worldwide. Designated administrators at each institution will log additions, edits and updates for validation by PSI and these will be made available to publishers.

Either manually or via our API, publishers will populate their access management systems with the appropriate and validated IP addresses for each customer organisation or consortium.

Publishers can be confident that only the licensed organisations are accessing their content and that their usage stats provide a true reflection of actual access.

Eyes down for the afternoon session at #APE2017 with the focus on a transition to #OpenAccess across Europe

And that's lunch on Day1 of #APE2017 after an examination of 'Integrity in Academic Publishing' from the viewpoint of all stakeholder groups

Battle for Berlin scars still visible inside the Berlin Brandenburg Academy of Sciences & Humanities #APE2017

Of the 60,000 organisations with validated IP ranges in the Registry 40% are academic, 40% are corporate and 20% are government

A belated Happy New Year to all our followers. We're working hard to launch the Registry soon and have made major breakthroughs this week 🙂
