Bridging the Digital Gap (Part I)
By isabelle.reynolds-logue.13, on 16 July 2019
I joined UCL in October 2018 as the Bridging the Digital Gap trainee from The National Archives. I have been learning about all things digital in relation to archives, working with UCL’s Special Collections and the Institute of Education archives. In order for me to produce meaningful work with the material, I first needed to understand a bit more about archive repositories and what they contain. As part of my training, The National Archives runs a Moodle course where I have learned about archives, records and repositories, as well as about a key problem facing holders of archives today: digital preservation.
My work so far has ranged from cataloguing to digitising material. A key part of my work at UCL has been digitisation. I photograph or scan original items so that they can be put online and be made more accessible to a wider audience. In addition to accessibility, digitisation aids in preservation. The copies of the original items generated through digitisation are archived so that we have a digital version in case anything happens to the original, or if, for example, it becomes too fragile for readers to view in person.
Most of the time I use a Canon EOS5D camera alongside a Kaiser RS1 copy stand and lights for digitisation. For some material I use an Epson12000XL flatbed scanner. Some items cannot be completely flattened for scanning, for example rare books, as this would cause severe damage to the item. In these cases, I will always use the camera and copy stand. In digitisation, we aim to get the most true to life image of the item whilst handling and moving the item as little as possible, in order to cause the least damage or deterioration to it. As digitisation requires handling and placing items in particular ways, we must liaise with the conservation team prior to digitisation, to make sure the item is in a suitable condition to be used. If an item is badly torn, falling apart, or very dirty, for example, it would have to be conserved before digitisation.
Once all of this is sorted out, I capture the photographs in RAW before editing them in Adobe Photoshop and saving them as high quality TIFF files for archiving, and JP2 files for use online. For some items with text, it is possible to use OCR software such as Nuance to generate searchable PDFs. However, some text proves too tricky for the software to pick up, for example unusual fonts or handwriting, so we don’t use it every time. However, we have begun to work with the OCR for handwriting software, Transkribus, so watch this space!
Now that you have an overview of what I have been up to, stay tuned for the next post where I will show you some of my favourite projects so far…
