What is Entry in Library Science
The reader wants to explore any book from different dimensions. If someone remembers the author's name, he would like to search with the author; If someone remembers the legend, he would like to search through the legend; A subject wants to search with access.

Thus, keeping in mind the different approaches of the readers, various entries of a single book is made and those entries are arranged in a catalog cabinet in ascending order provided that the list is in sheet format.

Types of Entries

Generally, there are two types of entry, it can be understood as follows:

Type of Entries
Type of Entries

Parts of Main Entry A main entry is made for each book. The main entry is divided into the following five parts -

1. Heading
2. Description
3. Tracing
4. Call No.
5. Accession No.

1. Heading - The title of the main entry is the most important part. The title either gives the name of the author of the book or gives the title. It starts with the first margin on the mainline.

2. Description - Description is the largest part of the main entry. It has the following eight fields

  1. Statement of account
  2. Edition
  3. A specific description of the type of document or publication
  4. Publication, distribution, etc.
  5. Alphabetical description
  6. Granthamala
  7. Comment
  8. Standard Number and Availability Terms.

3. Tracing - Under this, the title of the redundant entries to be made in addition to the main entry is given in a separate paragraph and it is written at the end.

4. Call Number - Under this, there is a class number and a text number. The square number starts writing from the leftmost edge of the listing sheet on the line just above the mainline and it moves straight forward on the same line. The text number is written from the leftmost edge of the listing sheet on the mainline. Since the number is small, it ends before the title. The index is written with a pencil.

5. Accession Number - It is written on the fourth lower line, counting the mainline. Added Entry - In the lexicographic list, which is constructed according to the rules of AACR 2, the unit sheet method for redundant entries is adopted.

According to this method, as many copies of the main entry are prepared as exact entries are to be made. The title of the redundancy entry on each of those copies is written on the first line from the second margin. If the first line is not working then the second line is used with the third imaginary margin.

1. Subject Added Entry - Subject redundancy entry is made first in redundancy entries. This requires a subject title.

Texts like 'Sears List of Subject Headings', 'Library of Congress Subject Headings', etc. are used for standard subject titles. All the subject titles are described in sequential order in this book.

2. Author Subject Added Entry - Author Subject Added Entry needs to be created only if there are books written by more than one author. 

For example, if there are texts written by two authors and neither of them is the head writer, then the first author is given in the title of the main entry and the second author is made under the author's redundancy. 

If there is a book written by three authors and none of them is the lead author, then the first author is given the title of the main entry and two author redundancy entries are made separately for the remaining two authors. 

In the case of works with more than three authors, we first, see if there is a principal writer or if the principal is not the author, then only the author is made redundant from the first author.

3. Title Added Entry - The need to create a title redundancy entry occurs when the main entry is made under the author. If the main entry is made under the number then it is not necessary to create a redundancy entry.

Since the main entry with the first-level description does not mention co-operatives and texts, there is no need to create redundant entries from these approaches.
