Backlist Digitization Services: What Publishers Should Check Before Choosing a Partner

Your Backlist May Hold More Value Than You Think

A publisher may have thousands of valuable titles sitting in print archives, scanned PDFs or older digital formats.

The content still has value.

The problem is that it may be difficult to search, reuse, distribute or prepare for modern digital publishing.

This is where backlist digitization services become important.

But digitization is not simply about scanning every page.

The real question publishers should ask is:

“Can this content be converted accurately into structured, searchable and reusable digital assets?”

A good digitization partner should be able to answer that question clearly.

What Are Backlist Digitization Services?

Backlist digitization is the process of converting older publishing content into modern digital formats.

The source may be:

• printed books;
• scanned pages;
• image-based PDFs;
• older digital files;
• archived publishing assets.

The required output may include:

• searchable PDF;
• EPUB;
• accessible EPUB;
• accessible PDF;
• structured XML;
• POD-ready files;
• reusable digital content.

A typical workflow may look like:

Assess → Scan → OCR → Structure → Convert → Validate → QA → Deliver

Each stage matters.

A problem introduced during scanning or OCR can affect every stage that follows.

What Should Publishers Check Before Choosing a Partner?

Choosing a backlist digitization provider should not be based only on page price or turnaround time.

Publishers should understand how the complete workflow is managed.

A reliable partner should be able to explain the process from source intake to final delivery.

Why Scanning Alone Is Not Digitization

Scanning creates a digital image of a page.

That is useful for preservation, but an image alone does not automatically make the information easy to search or reuse.

Imagine a publisher scans a 300-page academic book.

The pages now exist digitally.

But can a reader search for a particular phrase?

Can the publisher extract the text?

Can the book be converted into EPUB?

Can sections be identified automatically?

If the answer is no, the content still has limited digital value.

That is why scanning is normally only the first production stage.

OCR Turns Page Images Into Usable Text

OCR converts text visible in scanned pages into machine-readable text.

This makes content searchable and gives production teams a foundation for further digital conversion.

But OCR quality depends heavily on the original source.

Older books may contain:

• faded printing;
• damaged pages;
• unusual fonts;
• multi-column layouts;
• footnotes;
• tables;
• mathematical expressions;
• captions;
• text mixed with illustrations.

An OCR process may recognise most of the text correctly while still introducing small errors.

For publishing content, those errors matter.

OCR should therefore be followed by appropriate quality checks rather than treated as the final output.

Structure Is What Makes Content Reusable

Correct words alone are not enough.

A publication also has relationships between those words.

For example:

Book → Chapter → Section → Subsection → Table → Figure → Footnote

If those relationships disappear during conversion, the text may still exist, but much of the publication's meaning and organisation is lost.

Structured conversion preserves those relationships.

That makes the content easier to use for:

• EPUB production;
• digital distribution;
• accessibility;
• online publishing;
• content reuse;
• future format conversion.

For publishers with large backlists, structured content can create value well beyond the original digitization project.

When Should EPUB Be Included?

Publishers planning digital distribution should decide early whether their backlist also needs EPUB conversion.

Waiting until later may mean processing the same content multiple times.

Compare these two workflows.

Separate Workflow

Scan → OCR → Store

Then months later:

Open again → Structure → Convert → Remediate → QA

Integrated Workflow

Scan → OCR → Structure → EPUB → Accessibility → QA → Delivery

An integrated workflow can reduce repeated handling when the publishing objective is already known.

The right approach depends on the title, source and intended use.

Accessibility Should Be Discussed Early

Accessibility is easier to manage when it is considered while the content is already being structured.

For suitable digital publications, this may include:

• semantic headings;
• logical reading order;
• navigation;
• meaningful image descriptions;
• table structure;
• accessible EPUB;
• accessible PDF;
• accessibility metadata;
• human accessibility QA.

If a publisher converts thousands of titles first and considers accessibility only afterwards, additional remediation may be required.

A better question at the beginning of the project is:

“What will these titles need to support when production is complete?”

That helps define the correct workflow before large-scale conversion begins.

Why a Pilot Batch Matters

A publisher should not discover major workflow problems after hundreds of titles are already complete.

A pilot batch helps test the process before production scales.

The pilot should contain different types of publications.

For example:

Simple title
Mostly paragraphs and standard headings.

Medium-complexity title
Images, tables, footnotes and references.

Complex title
Academic, technical, STEM or heavily illustrated content.

Testing only the easiest title gives an incomplete picture.

“A useful pilot should test the difficult parts of the backlist, not simply prove that the easiest book can be converted.”

A Better Workflow for Large Backlists

1. Inventory

Understand how many titles exist and what source formats are available.

2. Sample

Select representative books from different categories and complexity levels.

3. Classify

Group titles according to source quality, layout and conversion complexity.

4. Define Output

Decide whether each group requires PDF, EPUB, XML, POD or other formats.

5. Pilot

Test representative titles before starting full production.

6. Convert

Run scanning, OCR, structural conversion and digital production.

7. Validate

Check technical quality and required output specifications.

8. Human QA

Review accuracy, meaning, accessibility and important complex content.

9. Correct

Resolve identified issues and apply lessons to later batches.

10. Deliver

Complete final QA and prepare approved files for delivery.

This turns thousands of individual books into a controlled publishing programme.

7 Questions Publishers Should Ask Before Starting

1. What condition are our source files in?

Poor-quality scans and older books may require a different workflow from clean digital PDFs.

2. What digital outputs do we actually need?

Decide whether the content requires searchable PDF, EPUB, XML, POD or several formats.

3. How will OCR accuracy be checked?

Recognising text and verifying text are not the same task.

4. Will content structure be preserved?

Headings, lists, tables, notes and sections should remain meaningful after conversion.

5. Should accessibility be included now?

Adding accessibility during conversion may prevent another large remediation project later.

6. How will difficult titles be handled?

Complex tables, STEM material, images and unusual layouts may need specialist workflows.

7. How will quality stay consistent at scale?

The process should include clear specifications, QA checkpoints, corrections and final acceptance criteria.

“The objective is not simply to digitize more books. It is to create digital content publishers can confidently use again.”

• scanning and digitization;
• OCR and post-scan processing;
• EPUB2 and EPUB3 conversion;
• XML and structured-content conversion;
• backlist conversion;
• accessible EPUB;
• accessible PDF remediation;
• POD;
• typesetting and composition;
• digital-content production;
• publishing QA;
• human accessibility QA.

Gentize has completed a 35,000+ title large-scale academic digitization project, delivering scanning, OCR, EPUB, POD, and accessible PDF.

Gentize also has 1,000 books per day digitization capacity, supported by a 200+ member production team.

For publishers with large backlists, the focus is not simply on converting individual titles.

The goal is to build a production workflow that can maintain accuracy, structure, accessibility and quality across large volumes.

Final Takeaway

Backlist digitization should not end with a scanned page.

A stronger workflow brings together:

Scanning + OCR + Structure + Digital Conversion + Accessibility + QA

For one book, that creates a useful digital publication.

Across thousands of titles, it creates something more valuable:

a searchable, reusable and future-ready publishing backlist.
