There are three types of inner forms of a catalogue, viz. alphabetical, classified and alphabetico-classed. Author, Name, Title, Subject and Dictionary catalogue fall in the category of an alphabetical catalogue.
A Classified Catalogue is so named because it is arranged in a classified order. Classified order is an artificial order which may be difficult to use. Hence a classified catalogue has two parts the other part being alphabetical which is easy to use and leads the user to the classified part. Alphabetico-classed catalogue is a variation of the classified catalogue. It overcomes the shortcoming of the artificiality of a classified arrangement by making it classified alphabetically.
Author Catalogue
Author is the person who is chiefly responsible for the intellectual thought content of a work. In simple words, author is the creator of a work. In an author catalogue, the entries of documents are under author’s name and arranged alphabetically. It provides access to documents by the names of their authors. In other words, the leading section of an author catalogue would comprise the name of an author. An author is generally a person or a corporate body who is responsible for the thought contents of the document brought out under the name. Listing of personal names of author varies greatly because of the cultural traditions in the naming of person in different regions of the world. For example, names of persons in Western countries, Indic names, Muslim names, Chinese and Japanese names differ as per their own traditions.Which part of the names should be taken as the lead in a catalogue has been set by cataloguing codes and there are established practices. There are also a variety of corporate bodies under whose names documents are published. Although we are not concerned very much with rendering of names in catalogue entries here, it is important to note that their filing position is determined by the rendering of names. Inaccuracies in the rendering of names would seriously affect the alphabetical arrangement of entries in the catalogue.
The catalogues of the British Library, the Library of Congress, the National Library of India are some of the fine examples of author catalogues. Libraries may have author catalogues arranged in three different ways:
a) There may be an exclusive author catalogue without entries mixing it with any other entries such as titles, subjects, series, etc.
b) Author entries may form part and parcel of a dictionary catalogue.
c) Author entries may form part of the alphabetical index of a classified catalogue.
Irrespective of the form in which an author catalogue exists, it provides an important approach to a document. If the user approaches the catalogue with the correct name of an author, the catalogue immediately gives the person all the documents by the author. To help a user, the other variants of the name of an author are usually provided as cross-references in a catalogue.
Advantages of Author Catalog:
1. Grouping of Works: It organizes books by the same author in one location within the catalog, making it convenient for users to find all works by that author in one place.
2. Quick Identification: Users can easily identify which books in the library are authored by a specific writer, providing quick access to an author's works. However, this function can also be fulfilled by author entries in other catalog formats.
3. Prevents Scattering: It prevents the scattering of works by the same author throughout the catalog, ensuring a more organized and user-friendly system.
Disadvantages of Author Catalog:
1. Limited Search Options: It doesn't cater to readers who want to search by subject, collaborators, distinctive titles, or other criteria, limiting the search options available to users.
2. Requirement of Exact Information: Users must know the exact name of the author and title for effective use. If an author is known by different names or pseudonyms, see references may be necessary to assist users in locating relevant materials.
Name catalogue
A name catalogue is an expanded version of an author catalogue that includes entries not only for works authored by an individual but also for books written about that author. This type of catalogue combines author and subject entries into a single alphabetical sequence, organizing entries by the author's name. In a name catalogue, various types of entries are included, such as autobiographies, biographies, critical studies, memoirs, and diaries of the author, in addition to their original works. The author entries encompass:
- Corporate authors, both as an author and as a subject.
- Name series.
- Place names that form part of an author heading.
A name catalogue functions both as an author catalogue and as a subject catalogue, making it a valuable resource for readers interested in works by or about a specific author. In this type of catalogue, materials authored by Rabindra Nath Tagore and materials discussing him would be listed together under the heading "Tagore" in a single alphabetical order. While this catalog format is more common in Great Britain, it is relatively rare outside of the United Kingdom. The British Library's catalog is a notable example, which includes references from all names occurring in titles.
Advantages of a Name Catalogue:
1. Comprehensive Author and Subject Access: It provides a comprehensive view of an author's works and materials related to them, allowing users to easily locate both their writings and books about them.

Disadvantages of a Name Catalogue:
1. Limited Subject Entries: Subject entries in this type of catalogue are primarily focused on personal and corporate names, potentially limiting the breadth of subject access for users seeking materials on broader topics.
2. Lack of Title, Collaborator, and Series Entries: This form of catalogue may not include entries based on book titles, collaborators, or series, which could be a limitation for users who prefer searching by these criteria.
A name catalogue is a valuable resource for those interested in specific authors but may have limitations in terms of subject access and other types of entries, such as title, collaborator, and series.
Title catalogue
A title catalogue is a cataloging system where entries are primarily organized in alphabetical order based on the titles of the documents. This type of catalogue is especially useful for readers who remember the exact title of a document they are looking for. However, it's important to note that many readers may not recall titles verbatim, particularly for non-fiction works. To accommodate readers with this kind of recall, title entries can be selectively provided in public library catalogs for fiction and well-known titles.

Advantages and disadvantages of a title catalogue:
Advantages of a Title Catalogue:
1. Specific Title Access: It effectively serves readers who have the exact title in mind, ensuring they can quickly locate the desired material.
Disadvantages of a Title Catalogue:
1. Specific Title Access: It effectively serves readers who have the exact title in mind, ensuring they can quickly locate the desired material.
Disadvantages of a Title Catalogue:
1. Limited Access for Other Approaches: A title catalogue is primarily geared towards satisfying the title-based approach, making it less suitable for readers who want to search by other criteria like author, subject, or genre.
while a title catalogue is valuable for those who recall specific titles, it may not adequately serve readers who prefer alternative approaches to finding materials in a library, such as author, subject, or genre-based searches. This type of catalogue is particularly preferred for classical languages and for organizing fiction, drama, poetry, and classical literature.
Alphabetical subject catalogue
An Alphabetical subject catalogue is a cataloging system where books are listed in a collection, and each entry is organized under the name of a specific subject as a heading. The entries are then arranged alphabetically based on these subject headings. This type of catalogue brings together several books on the same subject, making it easier for users to locate materials related to a specific topic.
Here's how entries are typically arranged in an alphabetical subject catalogue:
1. Subject Heading: Each entry is placed under a specific subject heading. This subject heading represents the main topic of the book.
2. Alphabetical Order: Entries under subject headings are arranged alphabetically. If there are multiple books on the same subject, the author's name is used to determine the alphabetical order. In cases where several books on the same subject have the same author, the title of the book is considered for arrangement.
The alphabetical subject catalogue is a useful way to organize a library's collection, ensuring that materials on similar topics are grouped together and easily accessible to users. This cataloging system helps users locate books based on their subject interests.

Dictionary Catalogue
A Dictionary Catalogue is a type of library catalog where all the entries, including authors, titles, subjects, and related references, are arranged together in a single alphabetical order, just like the entries in a dictionary.
Here are its features, advantages, and disadvantages:
Features of a Dictionary Catalogue:
1. Mixed Type: It combines two distinct approaches - the author and title approach for those who know the author or title and the subject approach for those seeking material on specific subjects.
2. Arrangement: Entries are strictly arranged alphabetically, resembling a dictionary's alphabetical order.
3. Subject Entries: Subject entries follow the principle of specific subject headings and are entered under the specific subject.
4. Cross References: Cross references are used extensively to unify related subjects and provide systematic and logical order. A dictionary catalogue with cross references is known as a syndetic or connective catalogue.
5. Two Files: It is divided into two files, one for author, title, series, and collaborator entries and another for subject entries.
6. Types of Entries: Various types of entries include personal, corporate, added entries, subject analytical entries, and cross-references (see and see also references).
Advantages of a Dictionary Catalogue:
1. Popularity: It is widely used in public, school, and college libraries due to its familiar alphabetical arrangement.
2. Satisfies Different Needs: It caters to the specific needs of readers who may approach the catalogue with different types of information in mind.
3. No Need for Class Numbers: Users do not need to be aware of classification numbers to use this catalogue.
4. Guidance through Cross References: Cross references and general references guide readers from one heading to another, aiding in information retrieval.
5. Direct Subject Access: It provides direct access to specific subjects. Readers can easily find books on a particular subject by looking it up in the catalogue.
Disadvantages of a Dictionary Catalogue:
1. Limited for Comprehensive Subjects: It may not be suitable for readers seeking comprehensive information on complex subjects, as it can be slower and less satisfactory compared to classified catalogues.
2. Bulky and Complex: Extensive use of cross references can make the catalogue bulky and complex, making maintenance more challenging.
3. Time-Consuming: For readers seeking information on various aspects of a subject, it can be time-consuming and tedious to navigate this catalogue.
4. Dependence on Verbalization: It heavily relies on textual descriptions, which can lead to difficulties when updating subject terms.
A dictionary catalogue is a widely used cataloging system due to its familiar alphabetical arrangement, but it may have limitations for readers seeking comprehensive subject information or dealing with extensive cross references.
A Classified Catalogue is a cataloging system that provides access to information primarily by subject and is distinct from an alphabetical catalogue in that it arranges entries based on class numbers. This system introduces an artificial aspect, as users are expected to be familiar with the library's classification scheme. To assist users in navigating the classified part, a classified catalogue typically consists of two parts, with the other part being alphabetical in nature.
Definition of a Classified Catalogue:
- According to the Encyclopaedia of Librarianship, it is "a catalogue of subject entries arranged in a systematic order according to a scheme of classification."
- Dr. Ranganatham defines it as "a catalogue in which some entries are numbered and some are word entries." Consequently, a classified catalogue consists of two parts: the classified part (with numbered entries) and the alphabetical part (with word entries).
Key Characteristics of a Classified Catalogue:
1. Subject Access: It primarily provides access to information by organizing entries according to class numbers, representing specific subjects.
2. Arrangement by Class Numbers: Entries are organized using class numbers that follow a predetermined classification system (e.g., Dewey Decimal Classification or Library of Congress Classification).
3. Artificiality: Users are expected to have knowledge of the library's classification scheme, which may pose a challenge for those unfamiliar with it.
4. Two-Part Structure: To assist users, a classified catalogue typically consists of two parts. The classified part arranges entries using class numbers, while the alphabetical part serves as a guide to help users navigate the classified section.
A classified catalogue offers structured access to information based on subject classifications. However, it relies on users' familiarity with the classification system and includes an alphabetical part to aid navigation within the catalog.
Classified Part:
- This part arranges entries by class number, providing a systematic and structured display of subjects.
- It reflects the logical thinking of specialists in various subjects.
- Verbal equivalents of class numbers, known as "Feature Headings," are provided to make the entries intelligible to users.
- The class number represents the subject matter of the book.
Alphabetical Part:
- It complements the classified part and includes author, title, subject entries, and other entries.
- Supports the classified part by fulfilling functions similar to a dictionary catalog, such as grouping works by an author, collecting different editions of a title, and cross-referencing subjects.
- Brings together related subjects and distributed relatives.
- Essentially, it allows the classified catalog to fulfill all the functions of a library catalog.
Features:
1. It's a subject catalog where entries are made under class numbers representing the book's subject.
2. Comprises two parts: classified (number entries) and alphabetical (word entries).
3. Success relies on the soundness of the chosen classification scheme and its ability to collocate subjects effectively.
4. Entries are arranged from general to specific.
5. Shortcomings in the classification scheme can affect the catalog.
Advantages:
1. Main entries closely align with related subjects, facilitating subject exploration.
2. Offers a logical and systematic arrangement due to its reliance on a recognized classification system.
3. Familiarizes readers with a large number of books due to the similarity between catalog entries and bookshelf arrangements.
4. Reveals the library's strengths and weaknesses by subjects.
5. Can produce printed parts class by class with a consolidated index.
6. Specific sections of classes can be used as subject bibliographies.
7. Arrangement based on notation supports international standardization.
8. Useful for exhaustive literature searches due to multiple approaches.
9. Can accommodate more readers simultaneously with separate catalog cabinets.
10. Changes in subject terminology have limited impact.
11. Index entries are user-friendly.
12. Entries in the classified part mirror bookshelf arrangement, while the alphabetical part resembles a dictionary, making it easy to understand.
Disadvantages:
1. Users need to consult the alphabetical part before the classified part, which may require additional steps.
2. Success depends on the chosen classification scheme; drawbacks can affect the catalog.
3. Revision of the classification scheme may necessitate corresponding revisions in the catalog.
A classified catalog offers a structured and systematic approach to organizing library materials by subject, supported by an alphabetical part.
