A collection is usually divided into the following categories: print books, online books, children's books, rare books, and special collections. Physical collections usually have a classification system to help them be organized, and digital collections usually use a computer program to do the same. The print collection includes books that are printed in some way, such as color, Braille, large print, and books made of cloth. The online collection includes books available electronically, whether in a format such as a PDF or EPUB for ebook readers, or in a format such as a digital video that can be viewed on a computer. The children's collection covers children's literature, usually in the form of pictures, comics, or other materials. This collection is sometimes divided into the picture book collection and the fiction collection.
There are many different formats used to store books, both in traditional print and online. Digital libraries use a variety of formats, including ebooks, a digital video medium that uses data compression and storing multiple images on a single disc. The advantage is that it is usually cheaper to produce discs than books and can hold more information. On the other hand, it is much harder to search for information, since there are usually no keywords. There are also substantial differences between online and print formats. Online formats are often not searchable for digital books, due to the lack of good search tools, and the search space is usually too large to allow a computer to search through. Online book readers typically access books either through dedicated electronic products, such as ebook readers, or through browsers such as Firefox or Internet Explorer.
Most libraries with book collections, whether physical or digital, provide access to their holdings to the public. A collection is usually thought of as a group of books that have been acquired for the purpose of use by the public. Collections can be public or private, and in many cases are both. Some collections are extremely valuable to the public, and thus may be under some kind of legal restriction about their use. This is often the case with rare books. Collections are either physical or digital. A physical collection is stored in a library or other place that is open to the public. A digital collection is accessible through a computer program or is available online. Some libraries make digital collections available online and some only provide access through a computer program.
This revolution in information, however, is not a revolution in communication. The ability to print information has not changed the nature of communication. Paper or electronic copies of information cannot be transmitted over long distances, so when they are printed they are read locally. The printed book or e-book cannot be seen on a screen. The only way to interact with it is by reading it or using a computer. A printed copy of information can only be read by a human being, but the electronic version can be read by any computer, which is already a human-like being. The electronic version of information can be shared on the Internet, where human beings can interact with it, and where it can be added to so that it can be shared by a greater number of human beings. Electronic information is not a new medium of communication. 827ec27edc
