What is Main Entry?

In library cataloguing, the main entry refers to the primary access point for a bibliographic record, serving as the central identifier for a resource. It is the key element used to organize and retrieve information about a specific item within a library’s catalogue. The main entry typically reflects the entity most responsible for the creation of the work, which can be an individual author, a corporate body, or, in some cases, a uniform title when the author is not readily identifiable or when the work has no clear author.

For example, in a book written by a single author, the main entry would be based on the author’s name. For instance:

• Main entry: Smith, John. The Art of Programming.

In this case, John Smith is the main entry because he is the sole author of the work.

However, when there are multiple authors, cataloguing rules vary, but the main entry is usually based on the first-named author. For instance:

• Main entry: Doe, Jane, and Smith, John. Collaborative Research Methods.

If a work has no identifiable author or is a collective work, the main entry may instead be based on a corporate body or organization. For example:

• Main entry: International Organization for Standardization. ISO 9001: Quality management systems.

In cases where the author is unknown or difficult to identify, or when there is a series of works with similar titles, a uniform title may be used for the main entry. For instance, many classical music scores or religious texts are catalogued under their uniform titles:

• Main entry: Bible. King James Version.
• Main entry: Symphony no. 5 (Beethoven)

The concept of the main entry has its roots in traditional cataloguing practices, where it played a critical role in ensuring consistency and standardization in library records. It remains essential for facilitating the discovery of materials, providing a clear point of reference for both cataloguing staff and library users. In modern cataloguing standards, such as Resource Description and Access (RDA), the approach to main entries has evolved, though its core function of creating a primary access point for library resources remains unchanged.

By establishing a main entry, libraries are able to maintain an organized, searchable catalogue, aiding users in locating materials based on their primary creator or title. Additionally, the main entry contributes to broader bibliographic control, ensuring that resources are catalogued and identified in a consistent, standardized manner that facilitates interlibrary sharing and access.

What is Main Entry?

Main entry in library cataloguing refers to the primary access point through which a library resource is identified and retrieved from the catalogue. It is the most important element in a bibliographic record, serving as the central reference for users seeking a specific resource. The main entry is typically determined based on the entity most responsible for creating the work, whether that is an individual author, a corporate body, or, in some cases, a uniform title. The purpose of the main entry is to provide a standardized way to access a resource, ensuring that the catalogue remains organized and searchable, facilitating easy discovery by library patrons.

In traditional cataloguing practices, the main entry was often linked to the name of the author or creator of the work. For instance, if a book was written by an individual author, the main entry would be based on that person’s name. In the case of a work with multiple authors, cataloguing conventions generally prioritize the first-named author as the main entry. In situations where a corporate body, such as an organization or government entity, is responsible for the creation of a work, the corporate body’s name becomes the main entry. For example, a document published by the United Nations would have the main entry as “United Nations.”

In some cases, especially when the author is not identifiable or the work is part of a well-known series, a uniform title is used as the main entry. This is common in works like religious texts or classical music compositions, where the title of the work itself serves as the primary access point. For example, the main entry for the Bible would be listed under the uniform title, rather than the name of any specific author or translator.

The main entry plays a crucial role in bibliographic control, helping libraries maintain consistency across their catalogues and ensuring that resources are catalogued in a standardized manner. In the modern era, cataloguing standards like Resource Description and Access (RDA) have refined the process of determining main entries, providing flexibility while maintaining clarity in how resources are accessed and discovered. Regardless of the specific approach used, the function of the main entry remains the same: to provide an efficient, consistent, and easily navigable cataloguing system that allows users to find resources based on a clear and identifiable starting point.

The Purpose of a Main Entry in Library Cataloguing

The main entry in library cataloguing serves as a critical element for organizing and retrieving resources within a library’s catalogue. Its primary purpose is to provide a clear, standardized access point for each resource, ensuring that users can easily locate and identify materials. The main entry typically reflects the entity most responsible for the creation of a work, whether it is an individual author, a corporate body, or, in some cases, a uniform title when an author is not clearly identifiable. This organization allows library materials to be catalogued in a way that is consistent, ensuring that all works by a particular author or under a specific title are grouped together for easy discovery. For example, when searching for books by William Shakespeare, the catalogue will list all his works under his name as the main entry, facilitating the user’s search and increasing the likelihood of discovering additional related materials.

The main entry enhances the discoverability of resources by ensuring that similar works are grouped under a consistent reference point. This is particularly important when cataloguing works in various formats or editions, as the main entry remains the same regardless of the version or format. It also plays a vital role in bibliographic control, which ensures that resources are catalogued uniformly and consistently. This is crucial for interlibrary collaboration, as libraries rely on shared cataloguing standards, such as those outlined in Resource Description and Access (RDA), to maintain consistency across their records. A uniform main entry system allows libraries to manage and exchange cataloguing records more effectively, making resources easier to find and access, especially in large library networks.

In addition to improving access, the main entry is key to standardization in cataloguing practices. By adhering to established cataloguing conventions, libraries ensure that their cataloguing systems are aligned with international standards, such as those found in the Anglo-American Cataloguing Rules (AACR2). This standardization allows users to navigate various catalogues with similar expectations, promoting ease of use and efficiency across different institutions. Moreover, the main entry serves as the primary reference for citation purposes, ensuring that users can cite library resources accurately and consistently. Whether it is a book written by an individual author, a corporate body, or a classical work like the Bible, the main entry provides a reliable and standardized reference for proper citation.

How to Determine the Main Entry for a Book or Other Library Resource

Determining the main entry for a book or other library resource is a fundamental aspect of the cataloguing process. The main entry serves as the primary access point to a resource, and accurately assigning it is crucial for ensuring that the resource is properly catalogued and easily discoverable by users. The process of determining the main entry involves a series of guidelines and conventions that help catalogers identify the most appropriate point of access for a particular work. These guidelines vary slightly depending on the cataloguing standard in use, such as the Anglo-American Cataloguing Rules (AACR2) or Resource Description and Access (RDA), but the core principles remain consistent.

1. Primary Creator of the Work: Author, Corporate Body, or Creator

The main entry is usually determined by the entity most responsible for the creation of the work. In most cases, this is the author or creator of the resource. For instance, when cataloguing a book written by an individual author, the main entry is typically based on that author’s name. Catalogers will list the author’s name in the author-main entry format, which ensures that the resource can be found under the author’s name in the catalogue. For example, for a book titled The Great Gatsby by F. Scott Fitzgerald, the main entry would be:

• Main entry: Fitzgerald, F. Scott. The Great Gatsby.

In cases where a resource is created by a corporate body, such as an organization, government agency, or institution, the main entry would reflect the name of the corporate body. For example, a publication by the World Health Organization would have the main entry as:

• Main entry: World Health Organization. Global Health Report 2024.

2. Multiple Authors or Contributors

When a work is authored by multiple individuals, the main entry is usually based on the first-named author or the creator according to the cataloguing rules. In the case of a collaborative work, catalogers typically list the first-named author or contributor as the main entry and may include others as additional entries, known as added entries. For example, for a book co-authored by Jane Doe and John Smith, the main entry would typically be:

• Main entry: Doe, Jane, and Smith, John. Research in Modern Technology.

However, when the work is a collaborative effort with no clear primary author, catalogers may use the title or another significant creator as the main entry.

3. Title-Based Main Entry:

In some cases, the main entry is based on the title of the work itself, especially when there is no identifiable author or when the author’s role is not prominent. This often occurs with works such as classical music compositions, religious texts, or collective works. For instance, for the Bible, where no single author is credited with its entirety, the main entry would be:

• Main entry: Bible. King James Version.

Similarly, for musical compositions like Beethoven’s Symphony No. 5, the title of the work serves as the main entry:

• Main entry: Symphony No. 5 (Beethoven).

4. Corporate or Conference Authors:
When a work is created by a corporate body, a conference, or an event, the main entry will reflect the name of that body or event. This includes works produced by organizations, government entities, or associations. For example:

• Main entry: American Library Association. Library Trends and Challenges in the 21st Century.

If a work is the result of a conference, such as a collection of papers or proceedings, the main entry may be based on the name of the conference or event:

• Main entry: Proceedings of the 2024 International Conference on Digital Libraries.

5. Uniform Title Main Entry:
In cases where a work is known by a specific title rather than an author or creator, such as a series or multi-volume work, a uniform title may be used as the main entry. This is common for classical works, collections, or editions of important texts. For example, different versions of The Odyssey may be catalogued under a uniform title like:

• Main entry: Odyssey. English.

6. Special Cases: Translators, Editors, or Creators of Adaptations-
In cases where the work is a translation, adaptation, or compilation, the main entry may be based on the translator, editor, or adapter rather than the original author. For example, if a work is translated into English by an individual, the main entry may reflect the translator’s name:

• Main entry: Sutherland, R. J. (Translator). Don Quixote by Miguel de Cervantes.

Similarly, for a compiled work or anthology, the editor may be designated as the main entry:

• Main entry: Harris, Mark, ed. Best American Short Stories 2024.

Determining the main entry for a book or other library resource involves following established cataloguing guidelines that prioritize the creator or title of the work. The main entry reflects the primary point of access for the resource, making it easy for users to locate and discover materials within the library catalogue. Whether based on an individual author, a corporate body, a uniform title, or a translator, the process ensures that each resource is catalogued in a consistent and standardized manner, contributing to the overall effectiveness and usability of library systems. By following these principles, catalogers maintain an organized, user-friendly catalogue that supports both library staff and patrons in accessing information efficiently.

The Role of the Main Entry in Organizing Library Collections

The main entry plays a pivotal role in organizing library collections by serving as the central access point for each resource, ensuring that materials are catalogued and retrieved efficiently. This organizational structure is crucial because it allows users to locate resources quickly and consistently. The main entry is typically based on the entity most responsible for creating the work, such as the author, corporate body, or title, and it helps to centralize similar works or related resources under a single access point. For example, if a user is searching for works by a specific author, all of that author’s works will be grouped together under their name in the catalogue, facilitating an organized search experience. The main entry not only centralizes access but also ensures consistency and standardization across the catalogue. Libraries adhere to established cataloguing conventions, such as Resource Description and Access (RDA) or Anglo-American Cataloguing Rules (AACR2), which help maintain uniformity in catalogue records. This consistency makes it easier for users to navigate different catalogue systems, as similar works are catalogued in the same way, regardless of the institution.

In addition to centralizing and standardizing resources, the main entry also plays a crucial role in supporting efficient search and discovery. By clearly defining the main entry for each resource, libraries create a system that allows users to find materials based on their preferred access point, whether that is an author, title, or organization. This structure streamlines the search process, especially in large libraries with extensive collections, making it easier for users to locate specific materials. Moreover, the main entry aids in cross-referencing and creating added entries, which further enhance search capabilities. For example, a book may be listed under both the author’s name as the main entry and the title as an added entry, allowing users to find the resource through either access point. This cross-referencing ensures that users can locate the same material from multiple search perspectives, improving overall discoverability.

The main entry is also vital in supporting bibliographic control, which involves managing and organizing catalogue records to ensure accuracy and consistency. Standardized cataloging practices allow libraries to track and manage resources effectively, which is especially important for libraries that share records with others. By using consistent main entries, libraries can exchange bibliographic data efficiently, fostering cooperation and resource sharing through systems like WorldCat or interlibrary loan services. Furthermore, the main entry plays a role in the classification of resources, as it helps categorize materials by creator or title, which supplements classification systems like the Dewey Decimal or Library of Congress classifications. For instance, all works by a particular author will be catalogued under that author’s name, making it easier for users to find related materials under the same entry.
