How to digitise archival materials with Transkribus

Think of an archive and you might think of old, dusty basements full of disorganised boxes of papers. But in the technological age, archives are taking on a new role. No longer are they purely physical collections of papers, manuscripts, or physical media, such as photographs or artwork. Instead, archives are becoming fully searchable digital collections, making it easier for researchers and the general public to access historical records and items from anywhere, at any time.

However, digitising an archive in this way is a challenge. A large national archive can hold millions of pages of text, which all have to be transcribed in order to produce digital versions. Previously, this was done manually — each individual word in the document was typed into a computer program by a human being. As you can imagine, transcribing in this way is a very time-consuming process and it would take literally decades to transcribe the millions of archival materials in a large archive.

That’s where Transkribus comes in. Transkribus is an AI-powered platform that uses machine learning to learn how to read a specific type of handwriting, no matter which language the text is in or when it was written. Once the platform can sufficiently recognise the handwriting, it can then transcribe thousands of pages at the click of a button.

In this post, we would like to give you an overview of the different kinds of archival materials which can be transcribed using Transkribus. You will learn how to process materials using the platform and there are also examples of archives which have successfully digitised their collections with Transkribus and made them fit for the future.

What are archival materials?

There are many different types of archival materials but they all have one thing in common: they are all primary sources. This means they were written at the time a particular historical event took place, usually by someone who was there. Because of this, archival materials are particularly useful for historical research and most items in an archive can be used as scholarly sources. Some of the key types of archival materials include:

Manuscripts: These are any kind of material that is written by hand (“manu scripti” is Latin for “handwritten”). The oldest manuscripts still surviving today are thousands of years old and extremely fragile. Handling archival material such as old manuscripts is a delicate task and so creating digital versions of them makes it possible for everyone to access the contents without damaging the manuscript.

Archival records: These are documents written by individuals or organisations to keep a written account of events such as births, deaths, meetings, finances, and many others. According to the SAA Glossary, the term “archival record” usually denotes unpublished documents, rather than published artefacts such as books.

Letters, diaries, and personal papers: These very important types of material give an insight into the lives of the people who wrote them and the world they were living in at the time. They are particularly useful when studying a single individual or small group.

Organising archival materials is more than just writing a description and putting it on the right shelf. Each item is classified according to several “elements”, which are included in the archival description. These include intellectual elements, such as the name, date and type of material; physical occurrence elements such as the number of pages or location; and the media occurrence element, which covers the media type, colour, dimensions, piece count, and reproduction count. These archival materials elements make it easier for someone to find a certain material and immediately understand its context.

A step-by-step guide to digitising archival materials with Transkribus

Transkribus is an AI-powered platform which converts handwritten or printed text into digital transcriptions. It is used in many different archives around the world to transcribe materials in just a fraction of the time it would take a human being. This allows whole collections to be quickly digitised and made accessible to everyone.

Below is a short overview of how to transcribe materials with Transkribus. For more details, check out our Help Center, which contains detailed information on each step of the process.

Step 1: Create images of the archival materials

To use Transkribus, you need high-quality images or scans of the documents you want to transcribe. These should be in JPEG, PNG or PDF format.

You can create images using anything from sophisticated scanning technology to just your regular smartphone. If you are using this second option, we recommend using a device such as the ScanTent, to ensure optimal lighting and image quality.

Step 2: Sign up to Transkribus

Before you can do any transcribing in Transkribus, you first need to create an account. Go to , click on “Sign up for free” and follow the instructions. Find out more about registration and login in our Help Center.

Step 3: Upload your images

Images are stored in “collections” on Transkribus. You can organise collections however you like. For example, a collection could include all the scans from a certain book or physical collection.

Start your collection by clicking “Tools” and then “Create a collection”. Once the collection has been created, select it on your Workdesk and then click “Upload” from the left-hand toolbar. You can then select the documents you wish to upload.

Your images and data will be stored on the servers of READ-COOP SCE, which are all located in Innsbruck, Austria, in a GDPR-compliant manner, and may be processed according to our terms & conditions. If data cannot leave your infrastructure for privacy reasons, check our On-Prem solution (

Find out more about creating collections and uploading documents in our Help Center.

Step 4: Create an automatic transcription

Open your collection and select a particular image. Click “Start automatic transcription” to begin the transcription process.

You will then need to select a model. This is a piece of code that contains all the information Transkribus needs to transcribe the text accurately. There are over 100 public models available, covering different languages and time periods. Select the one that is most relevant to your material and then click “Start”.

Once the processing is complete, the automatic transcription will appear on the right side of the screen. Find out more about automatically transcribing documents in our Help Center.

How to improve the accuracy and efficiency of your transcriptions

Public models like the ones described above are trained to transcribe a broad range of archival materials with reasonable accuracy. However, if you want to improve the accuracy or efficiency of your transcriptions, here are a couple of tips.

Check the quality of your scans

The better the quality of your scans, the better the automatic transcriptions will be. Therefore, it makes sense to check that all the text on your scans is clearly legible — as mentioned above, good lighting when taking the images helps a lot here. You should also make sure that there are no marks or other “noise” which might affect how Transkribus processes them.

Finally, check that all the scans were uploaded with the correct orientation (portrait or landscape), as this will also have an impact on the layout recognition. Rotate any incorrect scans back to their original orientation and re-upload them to Transkribus.

Improve layout recognition

Before the text can be recognised, Transkribus first needs to know where on the page the text is located. It does this using layout recognition. This analyses which parts of the document contain text and visibly marks each individual line. It is these lines of text which are then recognised by the platform.

However, that also means that if the layout recognition is incorrect, then the text will also be incorrectly transcribed. Therefore, any errors in the layout recognition must be corrected manually to ensure an accurate transcription. If you have a material based on a table — for example, a birth register — then you can also programme this separately into Transkribus, so that the platform recognises the rows and columns correctly.

Train a custom model

Transkribus doesn’t just provide public models, it allows you to train custom models, too. These are models that are tailor-made to your individual materials, resulting in more accurate transcriptions.

To train a custom model, you first need to manually transcribe around 5,000-15,000 words, depending on the complexity of the handwriting. Transkribus will then use this transcribed material to learn how to read the handwriting and create a model so that it can recognise similar texts in the future.

Many archives train custom models to recognise a specific type of collection, for example, council records from a particular time period or notarial deeds written by a select group of notaries. This allows the collections to be transcribed much more accurately, with less post-editing required afterwards. Find out more about training models in our Help Center.

3 archives that have successfully digitised their materials with Transkribus

Archives around the world have used Transkribus to transcribe many different types of materials and create digital versions of them. For more information about some of our most successful archival projects, check out the blog articles below.

Transcribing 3 million scans at the National Archives of the Netherlands

The National Archives of the Netherlands is home to literally millions of pages of material, both printed and handwritten. As part of their digitisation strategy, the archives used Transkribus to transcribe 3 million pages of records and notarial deeds from the 17th-19th centuries. The custom model they trained is also now available to all as a public model. Find out more about the project here.

Creating a digital scholarly edition of the Lovelace papers

Housed at the Bodleian Library in Oxford, the Lovelace papers are the private letters and memos of 19th-century mathematician Ada Lovelace. There are around 14,000 pages in all, which researcher Jessica Cook is using to train a custom model tailored to Lovelace’s individual handwriting, as well as the handwriting of other contributors, such as her husband and mother. Find out more about the project here.

How the State Archives of Zurich published 50,000 pages online

The State Archives of Zurich is a mine of historical information about the Swiss city. However, physically accessing the archive’s premodern collection was a challenge, prompting the archive to create a digital version which could be easily accessed online. Thanks to an accurate model, the team was able to transcribe and publish 50,000 pages of council minutes in just three years. Find out more about the project here.
