It’s been a while since we ran the Jerome project at the University of Lincoln, but it’s far from dead, and thanks to the recent leaps forward in establishing a proper data.lincoln.ac.uk (and data.ac.uk) portal, you can now access a permanent copy of our open catalogue data, at:

Just as in the original Jerome application, this data is constantly harvested from our catalogue over a number of days, one record at a time in an endless cycle.
It’s a ‘minimally invasive’ method that doesn’t put too heavy a load on the catalogue itself, or require us to run any additional software on our catalogue server – and it means that, on average, no record in the open data is more than a couple of days out of date. The data harvested is stored in Nucleus before being processed and published to data.lincoln.ac.uk.
If you have any technical questions about the process, it’s worth contacting LNCD (specifically, Nick Jackson).
The biggest difference between the original Jerome and this new process is that Jerome scraped XML views of catalogue records from our web OPAC, while son-of-Jerome harvests the records one at a time over Z39.50, using the YAZ PHP extension. We’re also publishing the data this time as BibJSON, rather than MakeItUpAsWeGoAlongJSON.
There’s a lot more data to come, including:
- Richer bibliographic data on each item (it’s somewhat bare-bones at the minute!)
- Library item data (i.e. copies of particular works)
- Reading lists
- Repository records
- Usage and activity data




The Jerome search portal itself is [still] at
