The document describes an e-library system being developed for a university. It includes 3 sections: [1] an introduction describing the goals of allowing students to access and borrow electronic books, library staff to manage operations, and data entry operators to input book information; [2] an initial use case diagram showing basic user interactions; [3] the process for students to select, view, and print pages from electronic books, which involves logging in, searching, selecting a book, choosing pages to print, and paying printing fees deducted from their account.

4. Introduction
This is the requirements specification document for the new E‐Library system. E‐Library system main
goals are to allow students and other staff member in the university to access the books available in the
library in an electronic format. The system will also allow the library staff to perform their daily jobs with
ease.
The students will be allowed to perform the traditional roles usually associated with them going to a
library; like borrowing a book, returning a book, and browsing the available books. In addition, the
system will allow the students to search books based on their author name, title, ISBN number, or a
specific book category. They will also be able to view books (from its first page or by picking a specific
page/section/chapter). Students should also be able to print a specific page/section, but not a whole
chapter or book. There will be a limit on how many pages students are allowed to print in total and per
book. Printing is allowed in two forms: paper prints and in PDF format.
To allow students to read books with pictures, the system should support attaching pictures (including
their captions) to the pages of the book. The pictures can be shown on top or the bottom of the page.
To allow students to borrow books, return books, and add extra credit/money to the printing account,
library staff uses the system to record all these transactions. The library staffs information is entered
into the system by the system administrator. All the actions of the library staff are logged into the
system to handle any complaints from students. The library staff cannot borrow books as it might
become a conflict of interest.
The book’s data entry operators are responsible for entering the book’s data of information, text and
pictures. These employees have the same access as the students and staff in addition to their specific
functionalities. Once the data entry operators enter the book information, they are asked to enter the
chapters’ information, then sections’ information. By selecting a specific section, the data‐entry
operator can enter pages into that section. The pages consists of text and possibly images. For each
page the data‐entry operator inserts the text (copied/entered) and then select if an image to be placed
in the top of the page or bottom of the page (if one needs to be added) with its caption.

6. Paper Printing Process
In order to print a selected section of a certain book, students undergo several steps: first, they need to
login into the system by entering their university ID and the previously chosen password. If the fail to
enter the correct combination at the first time they are asked to reenter their password again (with
maximum of three times), if they are failed to do so their account will be suspended.
Once students enter their login information they are directed to the homepage where they can select to
search for the required book using its name. If they do not find the book, they can place a request and
leave the system. If they find the book they start by choosing (clicking) the book from the available
results, and then proceed to the view page functionality. There they can choose where they can start
viewing the book (by specifying a page number).
Once the view page pops up, the students choose the print option and then enter the total number of
pages they wish to print. If the total number of pages is less or equal to the maximum number of pages
allowed to be printed, the user proceeds to the next step. Otherwise, the students are alarmed that they
cannot continue with this print request. In the next step, the student’s account information is checked.
If the account balance holds the required money to print the selected papers, the account is charged
with the printing cost.
The system then displays a message showing that the printing process is successful and where they can
find the printed papers (location of the printer). If the printing process fails, then the account balance
should not be deducted, and the student is shown an error message instead indicating the problem.
After that the student is directed back to the main screen. The student can cancel the printing error at
any stage to go back to the main screen.
