Assessing the coverage by LOCKSS of open access journals

At DMU we have an electronic journal digital preservation system using LOCKSS and an OpenURL Resolver using SFX that makes information available to people on which journal they can get access to and from where. We are the first university in the UK, at least, to get these two services talking to each other.

This has an advantage for staff and students at the university who can see and use the preserved journal articles when they are needed. I also gives us the chance to start assessing how running the LOCKSS service is helping to guarantee continuing access to the journals we value in the university.

For example, we can compare the Open Access journals recognised in the Directory of Open Access journals (DOAJ) with our local holdings in LOCKSS. SFX has a Collection Tool that enables this.

Of the 676 journal titles represented in LOCKSS at DMU 188 or 27% are journals in the DOAJ. More than a quarter of the journals being collected and preserved in LOCKSS are open access journals.

On the other side, of the 8524 journals in the DOAJ, that same 188 represents 2.2% of the journals. That covers the actual preservation work we are doing with this set of journals. The potential is likely to be higher, but we do only select the journals of interest to the mission of the university. If we were to attempt the preservation of DOAJ journals without discrimination we would find that 559 or 6.4% of journals could be covered.

This does look like at interesting area for further investigation. I can see a further blog post is called for taking this farther.
