Do PhD Dissertations Typically Require an ISBN?

When it comes to PhD dissertations and whether they require an ISBN (International Standard Book Number), there is often a bit of nuance to consider. Generally, it is not a common requirement, but there are certain circumstances and regions where obtaining an ISBN for a dissertation can be necessary. This article will explore the reasons why some PhD dissertations need an ISBN, including specific examples and the practice in certain locations.

Why ISBNs Are Not Common for PhD Dissertations

The most straightforward answer is that PhD dissertations are generally considered 'unpublished' and therefore do not necessarily require an ISBN. In much the same way as many other scholarly papers, books, and research materials, dissertations are primarily used for academic purposes and are not widely distributed or sold in the commercial market. As a result, they are often not assigned an ISBN unless specific circumstances call for it.

ISBNs for PhD Dissertations in Special Cases

However, there are instances where obtaining an ISBN for a PhD dissertation is necessary. This can be due to the significant printing requirements, distribution to libraries, and other specialized circumstances. For example, some academic institutions, particularly in countries like Sweden, may require an ISBN for each printed copy of a dissertation. This practice ensures that the work is easily identifiable and accessible in various cataloging systems.

Sweden: A Case Study

Sweden stands out as one of the places where PhD dissertations are more likely to have an ISBN. According to personal experience, it is a requirement in Sweden due to the extensive distribution networks. In this scenario, a large number of copies, often between 20 to 30, are printed and distributed to a wide range of libraries and other recipients. Each full professor in the department also receives a copy. Given the extensive print run, the department typically covers the costs associated with obtaining an ISBN.

For instance, a decade and a half ago, a personal dissertation involved approximately 70 printed copies. The academic institution handled the costs of publishing, including the acquisition of an ISBN. This demonstrates how the substantial volume and the specific recipients of the dissertation contribute to the decision to assign an ISBN.

European Examples

Further confirming the occasional need for an ISBN in academic contexts, a specific example from the Netherlands serves as a useful reference. An examination of doctoral theses from Europe reveals that some dissertations do indeed have ISBNs. These theses are often printed and bound in a professional manner, such as the perfect-bound B5 format.

A notable example is a dissertation titled 'Uncertainties in Segmentation and Their Visualization' by Arko Lucieer. Despite the fact that the author later moved to the University of Tasmania, the dissertation maintained its ISBN, signifying its formal academic status and print status.

Conclusion

While PhD dissertations usually do not require an ISBN, there can be exceptions, particularly in regions where extensive printing and distribution necessitate the assignment of a unique identifier. The decision to obtain an ISBN often depends on specific institutional requirements and distribution plans. Authors and institutions should understand the potential reasons for requiring an ISBN to ensure compliance with academic and publishing standards.

For further information and guidance, it is advisable to consult the specific policies of the academic institution or publisher involved in the dissertation's release.
