2. Book catalog: This is a catalog that is printed in book form, it is organized alphabetically by author, title, or subject, and it contains bibliographic information about the items in a library’s collection.
3. Microform catalog: This is a catalog that is stored on microfilm or microfiche, it is organized alphabetically by author, title, or subject, and it contains bibliographic information about the items in a library’s collection.
4. Electronic catalog: This is a digital catalog, it can be accessed through a computer or other electronic device. It contains bibliographic information about the items in a library’s collection, and it can be searched by keyword, author, title, subject, or other bibliographic data.
