Book pockets, also known as book covers, are pockets or covers that are placed on the inside covers of books to protect them from wear and tear. They are typically made of plastic or paper and have a clear or translucent front and a flap on the back that can be folded over the cover of the book.

Book pockets are used in libraries to protect the books from damage such as from spills, dust, and regular handling. They also help to keep the books in good condition and extend their lifespan. Book pockets can also be used to add identification to the book, such as a barcode or a call number, which can be used in the circulation process.

Book pockets come in different sizes and designs to fit different types of books and they can be adapted to the size and format of the book. Some book pockets are designed to be reusable and can be removed and repositioned easily, while others are designed to be permanent and are attached to the book with adhesive.

In summary, book pockets are an essential item for libraries, they help to keep the books in good condition, and make them easy to identify and circulate.

A barcode scanner is a device that is used to read barcodes and convert the encoded data into a digital format that can be understood by a computer. Barcode scanners are commonly used in libraries to automate the circulation process.

When a patron checks out an item, the library staff member will use a barcode scanner to scan the barcode on the item and the barcode on the patron’s library card. The scanner will then send the encoded data to the library’s computer system, which will update the item’s availability status and the patron’s account with the due date for the item.

When a patron returns an item, the staff member will use the barcode scanner to scan the barcode on the item, which will update the item’s availability status and remove the item from the patron’s account. If the item is overdue, the system will calculate any fines that are due and update the patron’s account accordingly.

Barcode scanners can also be used in other areas of the library, such as for inventory management, tracking the location of items on the shelves, or for security purposes.

There are different types of barcode scanners such as handheld, CCD, laser, and 2D barcode scanners. Handheld barcode scanners are portable and easy to use, while CCD scanners are small, lightweight and inexpensive, laser scanners use laser beams to read barcodes, and 2D barcode scanners are capable of reading 2D barcodes, which can store more information than traditional linear barcodes.
