Methods Used for Copying Documents and Library Materials: Complete Guide to Reprography, Scanning and Digitization
Introduction
Libraries are not only places where books and other information resources are collected and stored. They are also centers for accessing, reproducing, preserving, and sharing information. In many situations, library users need copies of articles, book chapters, reports, photographs, manuscripts, maps, newspapers, or other documents for education, research, reference, or personal study.
The process of making a copy or reproduction of a document is commonly associated with reprography.
Reprography has become an important area of modern library and information services. Traditionally, libraries depended mainly on photocopying and photographic reproduction. Today, technological developments have introduced scanners, digital cameras, multifunction printers, microforms, Optical Character Recognition (OCR), digital repositories, and other digitization technologies.
The method selected for copying a library material depends on several factors, including the type of material, physical condition, size, age, value, purpose of reproduction, required quality, available technology, cost, and copyright restrictions.
For example, photocopying may be appropriate for an ordinary modern textbook, while digital photography may be safer for a fragile historical manuscript. Similarly, scanning and OCR may be appropriate when a library wants to create a searchable digital version of a printed document.
This article explains the major methods used for copying documents and library materials, their advantages and disadvantages, applications, preservation considerations, and the role of modern technology in document reproduction.

Frequently Asked Questions
1. What Is Document Copying in Libraries?
Document copying refers to the process of creating a reproduction of an original document or information material.
A copy may be:
A paper copy
A photocopy
A scanned image
A PDF file
A digital photograph
A microfilm copy
A microfiche copy
A printed reproduction
A searchable OCR document
The purpose is usually to provide access to information while reducing the need to repeatedly use or handle the original material.
For example, if a researcher needs a particular article from an old journal, the library may reproduce the required pages rather than allowing the original volume to be handled repeatedly.
This can improve both access and preservation.
2. What Is Reprography?
Reprography is the process and practice of reproducing documents and information materials using various techniques and technologies.
In library and information science, reprography may include:
Photocopying
Scanning
Photography
Microfilming
Microfiche
Printing
Digital reproduction
Document imaging
OCR
Other reproduction technologies
Reprography is closely connected with library services because it allows information to be reproduced for authorized users and, in appropriate circumstances, supports preservation and digitization.
The development of reprographic technology has changed the way libraries provide information.
3. Why Do Libraries Copy Documents and Materials?
Libraries reproduce documents for many reasons.
3.1 User Requirements

A library may have:
Modern books
Old books
Journals
Newspapers
Manuscripts
Maps
Photographs
Government publications
Theses
Reports
Rare documents
Archival materials
Digital resources
Not all of these materials can be copied using the same technique.
The correct reproduction method helps libraries balance two important objectives:
Providing access to information + Protecting the original material
This balance is particularly important in special collections and archival libraries.
5. Major Methods Used for Copying Library Materials
The major methods include:
Photocopying
Scanning
Digital photography
Microfilming
Microfiche
Photographic reproduction
Printing
Optical Character Recognition
Digital duplication
Large-format reproduction
Each method has a different purpose and application.
6. Photocopying
Photocopying is one of the most familiar document reproduction methods used in libraries.
A photocopier creates a paper reproduction of a printed page.
Photocopying is commonly used for:
Book chapters
Journal articles
Reports
Notes
Printed forms
Reference materials
Ordinary documents
Advantages of Photocopying
Fast
Multiple pages can usually be copied quickly.
Convenient
Users can obtain physical copies immediately.
Easy to Use
Modern multifunction photocopiers are relatively simple to operate.
Suitable for Ordinary Documents
It works well with many modern printed materials.
Limitations
Photocopying may not be suitable for:
Very fragile books
Extremely old manuscripts
Materials with damaged bindings
Oversized documents
Certain valuable archival materials
Repeated photocopying can place physical stress on the original.
Therefore, librarians should carefully assess the condition of the material before copying it.
7. Scanning
Scanning converts a physical document into a digital image.
A scanner uses light and sensors to capture the appearance of a document and produce a digital file.
Common output formats include:
PDF
JPEG
TIFF
PNG
Scanning is one of the most important technologies used in modern library digitization.
Uses of Scanning
Libraries can scan:
Books
Journal articles
Reports
Manuscripts
Photographs
Newspapers
Maps
Theses
Archival documents
Advantages of Scanning
Creates digital copies
Enables remote access
Supports digital libraries
Makes preservation copies possible
Reduces repeated handling of originals
Allows digital backup
Can support OCR and full-text searching
However, scanning settings should be selected carefully because resolution, file format, color depth, and image quality affect the usefulness and long-term preservation value of the resulting file.
8. Digital Photography
Digital photography is another important method of reproducing library materials.
A digital camera or specialized document camera can capture a high-resolution image of a document.
This method can be particularly useful for:
Manuscripts
Rare books
Historical documents
Paintings
Photographs
Maps
Fragile materials
One advantage is that the original material does not necessarily need to be pressed against a scanner surface.
For valuable collections, libraries may use specialized photographic equipment and carefully controlled lighting.
9. Microfilming
Microfilming is a traditional document reproduction technology in which documents are photographed and stored on photographic film.
Microfilm was widely used for:
Newspapers
Government records
Historical documents
Journals
Archives
Large collections of printed records
One major advantage of microfilm is its compact storage.
Thousands of pages can be stored in a relatively small physical space.
Microfilm has also played an important role in preservation programs.
However, users generally need a microfilm reader to view the information.
10. Microfiche
Microfiche is another microform technology.
Unlike microfilm, which is commonly stored as a roll, microfiche uses flat sheets of photographic film containing reduced images of documents.
Microfiche was historically used for:
Reports
Technical documents
Theses
Journals
Catalogues
Government publications
Like microfilm, it significantly reduces storage requirements.
Although digital technologies have replaced microforms for many new projects, existing microfilm and microfiche collections remain important in many libraries and archives.
11. Photographic Reproduction
Photographic reproduction uses photographic techniques to create copies of visual and documentary materials.
It can be used for:
Historical photographs
Artwork
Manuscripts
Maps
Illustrations
Rare documents
Photographic reproduction can produce high-quality copies when appropriate equipment and expertise are available.
For special collections, controlled lighting and careful handling are particularly important.
12. Printing from Digital Documents
Libraries may also reproduce digital documents by printing them onto paper.
For example, a user may need a physical copy of:
An electronic article
A digital report
An e-book section where permitted
A digital thesis
An online document
Printers can create paper copies from authorized digital sources.
This method demonstrates how modern library reprography works in both directions:
Physical → Digital
and
Digital → Physical
13. Optical Character Recognition (OCR)
Optical Character Recognition (OCR) is a technology that identifies characters in scanned images and converts them into machine-readable text.
For example, a library may scan an old printed book. The scanner creates an image, but the text inside the image is not automatically searchable.
OCR can analyze that image and create a text layer.
This allows users to:
Search for words
Copy text where permitted
Extract information
Improve accessibility
Create searchable digital collections
OCR is particularly valuable for digitization projects involving large quantities of printed material.
However, OCR accuracy can be affected by:
Poor image quality
Old fonts
Damaged pages
Handwriting
Unusual layouts
Multiple languages
Historical printing styles
Therefore, human quality control may still be necessary.
14. Digital Duplication
Digital duplication involves creating an authorized copy of an existing digital file.
Examples include:
Copying a PDF to preservation storage
Creating backup copies
Moving files to a digital repository
Replicating data across secure servers
Digital duplication is extremely important for digital preservation.
However, simply having multiple copies does not automatically guarantee long-term preservation. Libraries also need appropriate file formats, metadata, storage management, integrity checking, and migration strategies.
15. Large-Format Document Reproduction
Some library materials are too large for ordinary scanners or photocopiers.
Examples include:
Maps
Architectural drawings
Posters
Engineering plans
Large photographs
Historical charts
Libraries may use specialized large-format scanners or cameras to reproduce these materials.
This is particularly useful in:
University libraries
Map libraries
Archives
Engineering libraries
Architectural collections
Special collections
16. Audio and Video Material Reproduction
Library collections are not limited to printed documents.
Libraries and archives may also hold:
Audio recordings
Music recordings
Interviews
Films
Educational videos
Oral history recordings
These materials may require specialized digitization equipment.
For example, an old analogue audio recording may be digitized into an appropriate digital audio format.
Similarly, older video formats may require specialized playback equipment and capture systems.
Digitization can help preserve content that might otherwise become difficult to access as older playback technologies disappear.
17. Reproduction of Rare and Fragile Materials
Rare and fragile materials require special care.
Examples include:
Ancient manuscripts
Palm-leaf manuscripts
Rare books
Historical letters
Old newspapers
Damaged photographs
Archival documents
Ordinary photocopying may not be appropriate for these materials.
Libraries may instead use:
Non-contact digital photography
Specialized scanning
Overhead scanning
High-resolution imaging
The objective should be to obtain a useful reproduction while minimizing stress on the original.
18. Reproduction of Maps and Drawings
Maps and technical drawings often contain fine details and may be larger than standard paper sizes.
For such materials, libraries may use:
Large-format scanning
Digital photography
Specialized reproduction equipment
High resolution is important because small details, symbols, labels, and lines may be essential to the usefulness of the reproduction.
19. Reproduction of Photographs
Photographs can be reproduced through:
Digital scanning
Digital photography
Photographic reproduction
High-resolution imaging
For historical photographs, color accuracy and resolution can be important.
Libraries should also record appropriate metadata about the photograph, including information such as:
Creator
Date
Subject
Description
Original format
Collection
Rights information
20. Reproduction of Newspapers
Newspapers are among the most frequently digitized library materials.
Historical newspapers can be:
Photographed or scanned.
Stored as digital images.
Processed using OCR.
Added to a digital repository.
Made searchable through a suitable discovery interface.
Digitization is particularly valuable for newspapers because old paper can deteriorate over time and newspapers may be heavily used by researchers.
21. Reproduction of Manuscripts
Manuscripts can present special reproduction challenges.
They may contain:
Handwritten text
Drawings
Marginal notes
Multiple scripts
Different ink colors
Fragile paper
Irregular page sizes
High-quality digital photography is often useful because it can capture the document without requiring aggressive physical handling.
Metadata and contextual information should accompany the digital reproduction so that researchers can understand its origin and significance.
22. Reproduction of Theses and Dissertations
University libraries often preserve theses and dissertations.
Older theses may exist only in printed form.
Libraries may digitize them by:
Scanning pages
Creating PDF files
Applying OCR where appropriate
Adding metadata
Storing them in institutional repositories
Digital thesis collections can make research more discoverable and accessible, subject to institutional policies and copyright restrictions.
23. Traditional vs Digital Reproduction

27. Copyright and Legal Considerations
Copyright is an important consideration when copying library materials.
A library may own a physical copy of a book without owning the copyright in the work.
Therefore, librarians and users should consider:
Copyright law
Licensing agreements
Permission requirements
Institutional policies
Fair dealing or fair use provisions where applicable
Restrictions on commercial reproduction
Privacy considerations
The exact legal rules vary between countries.
Libraries should therefore follow the copyright laws and institutional policies applicable to their jurisdiction rather than assuming that every document can be copied freely.
28. Preservation and Handling During Copying
Copying should never be treated as simply pressing a button.
The original material must be handled carefully.
Important practices may include:
Clean hands or appropriate handling procedures
Supporting fragile bindings
Avoiding excessive pressure
Controlling lighting and heat
Using appropriate scanning equipment
Avoiding unnecessary page turning
Using trained staff for special collections

| Existing digital files | Authorized digital duplication |
The final choice should always consider the material's condition, purpose, technical requirements, and legal restrictions.
34. Difference Between Copying and Digitization
These two terms are related but are not exactly the same.
Copying generally means creating another reproduction of a document.
Digitization means converting an analogue or physical resource into digital form.
For example:
Photocopying a book page = copying
Photographing a manuscript = reproduction
Scanning a book into a digital image = digitization
Applying OCR to the scanned image = creating machine-readable text
Digitization is therefore a broader process that often involves reproduction plus additional activities such as metadata creation, quality control, storage, preservation, and access.
35. Reprography as a Modern Library Service
A library's reprographic service can provide considerable value to users.
A well-managed service can help users obtain authorized copies of information while protecting library collections.
Modern reprographic services may combine:
Photocopiers + Scanners + Digital Cameras + Printers + OCR + Digital Repositories
This combination allows libraries to support both traditional and digital information needs.
Conclusion
Document copying and reproduction are important functions of modern library and information services. From traditional photocopying and microfilming to modern scanning, digital photography, OCR, and digital preservation, libraries use different technologies according to the type and purpose of the material.
Photocopying remains useful for many ordinary printed documents, while scanning and digital photography have become especially important for digitization and preservation. Microfilm and microfiche continue to have historical importance and remain relevant for existing archival collections. OCR adds another important capability by converting images of text into searchable digital content.
The selection of a reproduction method should never be based only on convenience. Librarians must consider the physical condition of the material, required quality, intended purpose, copyright, cost, preservation needs, technology, and user requirements.
For rare and fragile collections, careful reproduction can help provide access while reducing unnecessary handling of originals. For digital library projects, high-quality reproduction combined with metadata, OCR, quality control, secure storage, and preservation planning can transform historical collections into valuable digital resources.
As artificial intelligence, advanced imaging, cloud computing, and automated digitization continue to develop, the future of library reprography will become increasingly sophisticated.
Ultimately, the purpose of document reproduction is not simply to make another copy. It is to preserve information, improve access, support education and research, and ensure that valuable knowledge can continue to serve users in the future.
