Cataloguing of Web Resources

 

Cataloguing of Web Resources/Digital Materials and Retro-conversion


With the increasing use of digital resources and web-based materials, libraries and information centers must adopt specific cataloging practices to manage these types of resources effectively. Cataloguing of web resources and digital materials and retro-conversion are important processes for ensuring that digital content is accessible and organized for users.


Cataloguing of Web Resources/Digital Materials


Cataloguing digital materials such as websites, e-books, online journals, digital images, and other web-based resources requires the adaptation of traditional cataloging standards to account for the unique characteristics of these digital objects. The cataloging process ensures these resources are discoverable, organized, and easily accessible to users.


Principles and Guidelines for Cataloguing Web Resources/Digital Materials


1. Use of Metadata Standards:


Web resources and digital materials require metadata that conforms to international standards. Popular standards include Dublin Core and MARC 21 (Machine-Readable Cataloging), as well as specialized metadata schemas for different resource types.


Dublin Core is widely used for web-based resources and includes basic elements like title, creator, subject, description, publisher, date, format, and identifier.




2. Identification and Description:


Title: The title of the web resource should be recorded as it appears on the webpage or in the digital document.


Creator/Author: Identify the individual, organization, or entity responsible for the content. For web resources, this may be a company, government agency, or academic institution.


Date: For web resources, record the publication or last update date if available. If the date is not provided, use “[n.d.]” for no date.


URL/Identifier: Include the URL or any other unique identifier (e.g., DOI for academic articles) to ensure that users can directly access the resource.


Format: Specify the format of the digital resource (e.g., HTML, PDF, ePub, JPEG). For multimedia resources, note if they contain audio, video, or other media types.


Access: Indicate if the resource is freely accessible or requires special access (e.g., login or subscription).




3. Additional Elements:


Publisher or Sponsoring Organization: For web resources, this could be the website host, institution, or publisher (e.g., "Published by the World Health Organization").


Content Description: Provide a brief description of the resource’s content and purpose.


Language: Note the language(s) in which the resource is available (e.g., English, French, etc.).




4. Special Considerations for Digital Materials:


Preservation: Digital resources need to be preserved for long-term access. Cataloging systems should include details on the preservation format and requirements (e.g., PDF/A for archiving).


Digital Object Identifiers (DOI): For academic papers, research, and journals, DOIs provide permanent identifiers for digital content.


File Size and System Requirements: For downloadable resources like e-books or software, file size and system requirements should be specified to ensure users can effectively access the content.





Example of a Web Resource Catalog Record:


245 00 History of the Internet /

260 [Washington, D.C.] : National Science Foundation, 2020.

300 [1 screen] : HTML file.

520 An overview of the development of the internet from its inception in the 1960s to the present day.

Retro-conversion of Catalog Records


Retro-conversion refers to the process of converting legacy catalog da kota (often stored in physical or older computerized formats) into a more modern, standardized, and accessible format. This is particularly important as libraries move from traditional card catalog systems to automated library management systems (ALMS) or digital databases.


The Need for Retro-conversion


Transition from Card Catalogs: Many libraries still have physical card catalogs that are outdated and inefficient. Retro-conversion allows these records to be integrated into modern library systems, making them accessible and searchable digitally.


Digital Resource Integration: Libraries that have begun to adopt digital resources, such as e-books, digital archives, and web resources, may need to convert older catalog records to accommodate these new types of materials.


Improved Accessibility: Retro-conversion enables libraries to create comprehensive, searchable digital catalogs, improving resource accessibility for users.



Steps in Retro-conversion:


1. Data Extraction:


Physical Records: For physical card catalogs, data is manually entered into a computerized system. In some cases, Optical Character Recognition (OCR) technology is used to scan and convert text.


Legacy Databases: Older digital catalogs may need to be extracted from outdated formats (e.g., DOS-based systems) and converted into a modern format (e.g., MARC 21, XML).




2. Data Cleaning:


Validation: During retro-conversion, data may need to be cleaned to ensure accuracy. This includes fixing formatting errors, correcting typos, and ensuring consistency in bibliographic details.


Standardization: The converted records must conform to the required cataloging standards, such as MARC 21, to ensure compatibility with modern library systems.




3. Data Integration:


Import into New System: Once cleaned and standardized, the data is imported into the library's new cataloging system or database.


Mapping to Modern Formats: In cases where the legacy system uses proprietary or outdated formats, the data must be mapped to modern standards (e.g., Dublin Core for web resources or MARC for traditional materials).




4. Quality Assurance:


Verification: After conversion, the data should be thoroughly checked for errors, omissions, or inconsistencies. Some libraries run tests to ensure the data is properly integrated and that users can search and access records without issues.


User Feedback: After the system goes live, user feedback may be used to identify and correct issues with the retro-converted data.




5. Ongoing Maintenance:


Updating Records: As libraries continue to acquire new materials and resources, retro-converted records should be periodically updated to reflect new additions and metadata changes.





Challenges of Retro-conversion:


Time-Consuming: Retro-conversion can be an intensive, resource-heavy process, especially for large libraries with extensive legacy catalogs.


Cost: The process may involve significant costs for equipment, software, and staff time, especially when OCR technology or manual entry is required.


Data Integrity: Ensuring that legacy data is accurately transferred and formatted without loss or corruption is crucial for maintaining catalog integrity.



Example of a Retro-converted Record (from a physical card catalog to MARC format):


Original (card catalog):


Title: The Great Gatsby


Author: F. Scott Fitzgerald


Publisher: Charles Scribner's Sons


Date: 1925


Subject: Fiction



Converted to MARC format:


=245 00  The Great Gatsby /  

=100 1Fitzgerald, F. Scott, 1896-1940.  

=260 0  New York :  Charles Scribner's Sons, 1925.

Conclusion


Cataloguing Web Resources and Digital Materials: As libraries expand their digital collections, cataloging web-based and digital resources becomes critical. The use of metadata standards such as Dublin Core and MARC 21 ensures that these materials are discoverable and organized, supporting easy access for users.


Retro-conversion: The retro-conversion process is vital for libraries transitioning from physical card catalogs or legacy systems to modern, computerized systems. This enables libraries to integrate and manage both traditional and digital resources in a unified, efficient, and accessible catalog.



Both cataloging of web resources and retro-conversion contribute to the modernization of libraries, improving access to information and enhancing the user experience in the digital age.
