Modifying Book Data


Screenshot
     


Description
If a book exists in the database, it is possible to change the information about that book. It is not possible, however, to modify the ISBN number. If the ISBN number is wrong, the only way to change it is to delete the book with the incorrect ISBN number and proceed to add the book to the database with the correct ISBN number included. Modifying book data is not the same as modifying book copy data. Modifying a book allows for modification of data such as title, author, publisher, etc., while modifying a book copy allows only for the modification of location, floor number and circulation status.


How To Use This Function
  1. Left click on the 'Book Administration' button from the Main Menu. This will bring up the Book Administration menu.
  2. Left Click on 'View Book' button from Book Administration Menu. This will bring up the View Book form which contains an empty field for entry of the ISBN number of the book that will be modified.
  3. Enter ISBN number. If the ISBN number is valid, a window will be brought up which will display the book information of the book that corresponds to that ISBN number. Left click once on the 'MODIFY' button. This will allow for the modification of the data displayed.
  4. Proceed to enter/change field information. For a more detailed description about how to enter/change the book information, refer to the detailed user manual. For information strictly on data field format, refer to the reference manual.
  5. Once that is done, left click once on the 'SAVE' button.
     Once this process is completed without errors the Book (or whatever media type) is modified and saved in the database.
     To exit this information page, left click once on the 'EXIT' button. The system will then return to the View Book form. Note that if any fields have been modified, but the 'SAVE' button was not pressed, the changes will not be saved.
     To exit the View Book form, left click once on the 'CANCEL' button. This will return to the Book Administration menu. Note that if the ISBN number field has data entered, but the 'CANCEL' button is pressed, the system will not attempt to bring up the information about that book.
     To quit the Book Administration menu, left click once on the 'QUIT' button.
