- 11. 11 @BL_Labs #DHA2018 @BL_DigiSchol labs@bl.uk The Story of the Digital Collection… Digital Collection Curator Who paid for the digitisation? Who did the digitisation? Technology used Born digital? Published Unpublished Where is it? Access / API? Can it still be accessed? Generates income Reputational risk in using? Legalities / Ethics / Morality Politics when digitised Personalities involved Surprises (e.g. gaps) Descriptive information Old format not supported What media was the digitisation done from? Is there any background documentation? No Descriptive information Inconsistent descriptive information Still there? Good to know the background ‘story’ of a Digital Collection if you want to use it for projects …
- 12. 12 @BL_Labs #DHA2018 @BL_DigiSchol labs@bl.uk https://goo.gl/qpCLlk https://goo.gl/wMTS3Z • Dialogue typically: – you are ‘lucky’ & we have the digital content / data relevant to your research – we don’t have exactly what your looking for, but is there anything of interest? Let’s talk… – engagement is hard work and it’s constantly required to maintain interest in our digital collections! • Artists find this dialogue easier… • We also tend to attract researchers with ‘fuzzier’ research boundaries and possibly open to more interdisciplinary / collaborative research What engagement does the BL have with researchers wanting use our digital content?
- 13. 13 @BL_Labs #DHA2018 @BL_DigiSchol labs@bl.uk Open Content vs Onsite Only Access • Access easier for openly licensed content • More challenging for on-site, in-copyright, non-print legal deposit, data protected, old content media & contemporary material (post 1877) https://goo.gl/Y5zCXg ©

- 16. 16 @BL_Labs #DHA2018 @BL_DigiSchol labs@bl.uk Accessing digital collections onsite OPEN £ • Have to be ‘onsite’ (interpretations vary) • Need to be ‘security cleared’ ‘trusted’ for some collections – Hence ‘Researcher in Residence Model’ • Permission required (depending on ‘story’ of collection) • Content could be on various media formats (not always online) • 5 - 20 % re-use of material for non commercial research for some collections, depends on agreements in place • We are learning ‘pathways’ so that this becomes ‘everyday’ to provide onsite access to some digital collections in the future

- 20. 20 @BL_Labs #DHA2018 @BL_DigiSchol labs@bl.uk Working with British Library Digitised Newspapers • Digitised through public / private means • Can use commercial products to look manually for content, with search interfaces but no APIs, useful starting point though, manual methods can translate into computational ones • OCR quality is not great, metadata is OK, but plenty of hidden material, approaches require to consider this, e.g. ‘Good, Bad and Ugly’ OCR • You can purchase drives from GALE Cengage with content (dependent on subscription)
- 21. 21 @BL_Labs #DHA2018 @BL_DigiSchol labs@bl.uk Good, Bad, Ugly Image Quality / OCR • Original image capture of newspaper images can effect the quality of the OCR • A poor image, very difficult to re-OCR • Good image quality much better chance for re-OCR • Bi-tonal, Grey Scale, Colour can effect the quality of the OCR • Methodology of working with collection at scale needs to acknowledge OCR and image quality

Notes de l'éditeur
- 23 seconds (71 words) Though the project focusses on working and communicating with Digital Humanities and Digital Scholarship researchers, we have also engaged with amazing Artists, Librarians, Curators, Educators, Entrepreneurs, Archivists, Software Developers and other innovators. Hopefully, I will show you<CLICK> some inspirational examples of work they have done which have used our digital collections.<CLICK> I will also reflect on our experiences, challenges and lessons we have learned working with some amazing and pioneering people.
- 85 seconds The picture you can see is inside the main building in London, it’s the King’s Library – King George the Third’s personal library! Sometimes known as the ‘stack’, I walk past this everyday and I sometimes forget that the collections the British Library have are truly staggering! We currently estimate them to exceed <click>150 million items, representing every age of written civilisation and every known language. Our archives now contain the earliest surviving printed book in the world, the Diamond Sutra, written in Chinese and dating from 868 AD…. So some big numbers… Over …<click>14 million books <click>60 million patents <click>8 million stamps <click>4 million maps <click>3 million sound recordings <click>1.6 million music scores <click>over .3 million manuscripts <click>0.8 million serials titles (which are of course made up of many many volumes/editions), this is where a lot of our content is, just in case you thought the numbers didn’t add up!
- 28 seconds (85 words) This what I imagine it feels like for a researcher looking for our physical collections. <CLICK> Everything is on an industrial scale and it can feel overwhelming. Sometimes it isn’t always straightforward to find our items, as there are many that are not on our digital library catalogue, e.g. still on card catalogues and some items are in the secret and very secure parts of the Library where you would need very special permission because the items are extremely valuable and fragile for example.
- 24 seconds (72 words) The BL are world renowned experts in digitising materials from our physical holdings. One common misconception that many people have is that much if not all of our collections are digitised. So, the actual proportion of our collections that are digitised surprises many<CLICK> The figure is around 3% of our physical collections.<CLICK> Much of our digitisation activity happens through partnerships with commercial, philanthropic, charitable and foundation partners<CLICK> What is for certain, is the amount we are digitising is increasing rapidly. Our new programme called Heritage Made Digital for example prioritises those collections for digitisation where there is a clear researcher demand.<CLICK> One important thing we have learned is that researchers need to take heed when doing research based on our digital collections, as they are rarely complete, having gaps and not necessarily being representative of our physical collections.
- 36 seconds (109 words) Our digital offering is perhaps like this.<CLICK> Imagine entering a boutique sweet shop. We have some lovely things to tempt you, but it’s much smaller than the hypermarket you just visited. The shop keeper tells you there are some things behind the back door in a giant warehouse. However, you will need special access to enter that space. She also states that there are rooms in that warehouse, even she isn’t allowed to look. She isn’t even allowed to share the full list of stock because there are items on there she may never be able to be see because they were meant to be secret.
- 12 seconds (37 words). In another way, we are trying to match our audiences research needs and digital interests <CLICK> With the digital collections we have<CLICK> It is at this intersection where Labs works best and it usually starts with a conversation.
- 41 words (125 seconds) Our work in Labs has taught us that it always pays for researchers to know the back ‘story’ of a digital collection especially if they want to use it for research and analysis.<CLICK> There are too many things to consider right now, but a few highlights are such as, ‘are there gaps in the collection?’, ‘can they still be accessed?’, but perhaps most important of all is whether the curator or a human being who knows about the collection is still around who could be asked about it. Our experience has told us that so much will probably be in their head that isn’t written down, information that could be vital, important and useful for knowing about before carrying out research or re-use.
- <click>The British Library faces many challenges of access to our Digital collections! <click> Sometimes digital content is only available onsite due to license restrictions, <click>or even only on a specific computer in a reading room! Technically there are very few reasons why digital content can’t be online <click> though it might be too big or hasn’t been transferred from other digital storage media. <click>Sometimes access is through a paywall. Finally, <click>some content is in the happy sunny place, online, open and freely available. The real reasons why there are challenges to accessing digital content are of course human. They require different approaches from the Library and may often involve an honest, open dialogue and negotiation with the publishers. The Labs project has tried to address this problem my creating a ‘residency model’ for researchers to work intensively with a digital collection on-site, so as to not infringe access conditions, I will say more about this later.
- 24 seconds (72 words) Let’s look a little further at the types of interactions we have with our researchers. We have summarised these phases as ‘Exploration’ where people often ‘rethink’ their ideas of what they want to do with the data, ‘Query-Focused’ where they often have to iterate to come up with a realistic proposal of what they want to do and a ‘Wrap-up’ phase to end their project with us, if it is relevant.
- 970 files from a selection of 19th century newspaper titles from the BL corpus for us to correct using the overProof post-OCR correction software The best way to measure the improvement made by the correction process is to compare the OCR'ed text and the automatically corrected text with a perfect correction made by a human (known as the "ground truth"). Hannah-Rose's 5 small human-corrected samples are show as green dots. These are not only smaller than the other files, but their raw error rate is much lower at 13.3%. OverProof was measured as reducing this to 5.4%, a removal of almost 60% of errors. The red dotted-line indicates the correction "break-even" point: the further under the line, the better the quality of the document after correction. In the graph below, the grey line shows distribution of files across error rates before correction and the green line after correction.
- Posts small illustrations taken almost at random from the digitised book corpus to a Tumblr blog. This experiment with undirected engagement was a by-product of work to uncover the hidden wealth of illustrations within the digitised pages.
- 50 seconds Here is the anatomy of a Flickr record, importantly we have created links to many of the Library’s services <click>some of this lovely traffic is going back to the Library and hopefully generating more interest in our services, from downloading a pdf of the book to purchasing a high res scan of the image. <click>Tags are added from the original book record, including the approximate page number the image came from<click>users of Flickr can add their own tags, and I have mentioned they have already started doing it.
