PaperBackSwap
PaperBackSwap (PBS) is a book swapping website which was founded in 2004. The purpose of PaperBackSwap is to use the Internet to facilitate the parity trading of books among members in the United States using a credit based system for swapping. The club also operates sister websites SwapaDVD and SwapaCD to facilitate parity trading of DVDs and CDs, respectively. History PaperBackSwap was founded in 2004 by Richard Pickering, a former economics student, and his friend, Robert Swarthout. Sister websites SwapaCD and SwapaDVD were founded in 2008. Operation A credit system is used to enable members to trade books for credits and credits for books. Credits may either be purchased, or they may be earned by mailing books which have been requested. Consequently, a member need not seek another member who desires a parity trade; credits are the medium of exchange. Both paperback and hardback books may be traded, as well as audiobooks. Within the PBS system the value of any bound boo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Book Swapping
Book swapping or book exchange is the practice of a swap of books between one person and another. Practiced among book groups, friends and colleagues at work, it provides an inexpensive way for people to exchange books, find out about new books and obtain a new book to read without having to pay. Because swaps occur between individuals, without central distribution or warehousing, and without the copyright owner making a profit, the practice has been compared to peer-to-peer (P2P) systems such as BitTorrent—except that hard-copy original analog objects are exchanged. College book exchange programs Many colleges and universities have developed online book exchange programs to help students save money on textbooks. Some colleges build their own systems and others use systems from third party service providers. Informal book exchanges Some book exchanges are informal - a shelf or box is provided where books can be left or picked up. The exchange relies on users leaving an ...

Internet
The Internet (or internet) is the global system of interconnected computer networks that uses the Internet protocol suite (TCP/IP) to communicate between networks and devices. It is a ''internetworking, network of networks'' that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries a vast range of information resources and services, such as the inter-linked hypertext documents and Web application, applications of the World Wide Web (WWW), email, electronic mail, internet telephony, telephony, and file sharing. The origins of the Internet date back to the development of packet switching and research commissioned by the United States Department of Defense in the 1960s to enable time-sharing of computers. The primary precursor network, the ARPANET, initially served as a backbone for interconnection of regional academic and mi ...

Compact Disc
The compact disc (CD) is a digital optical disc data storage format that was co-developed by Philips and Sony to store and play digital audio recordings. In August 1982, the first compact disc was manufactured. It was then released in October 1982 in Japan and branded as '' Digital Audio Compact Disc''. The format was later adapted (as CD-ROM) for general-purpose data storage. Several other formats were further derived, including write-once audio and data storage ( CD-R), rewritable media ( CD-RW), Video CD (VCD), Super Video CD (SVCD), Photo CD, Picture CD, Compact Disc-Interactive (CD-i) and Enhanced Music CD. Standard CDs have a diameter of and are designed to hold up to 74 minutes of uncompressed stereo digital audio or about 650 MiB of data. Capacity is routinely extended to 80 minutes and 700 MiB by arranging data more closely on the same sized disc. The Mini CD has various diameters ranging from ; they are sometimes used for CD singles, storing up to 24 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Economics
Economics () is the social science that studies the production, distribution, and consumption of goods and services. Economics focuses on the behaviour and interactions of economic agents and how economies work. Microeconomics analyzes what's viewed as basic elements in the economy, including individual agents and markets, their interactions, and the outcomes of interactions. Individual agents may include, for example, households, firms, buyers, and sellers. Macroeconomics analyzes the economy as a system where production, consumption, saving, and investment interact, and factors affecting it: employment of the resources of labour, capital, and land, currency inflation, economic growth, and public policies that have impact on these elements. Other broad distinctions within economics include those between positive economics, describing "what is", and normative economics, advocating "what ought to be"; between economic theory and applied economics; between ratio ...

Medium Of Exchange
In economics, a medium of exchange is any item that is widely acceptable in exchange for goods and services. In modern economies, the most commonly used medium of exchange is currency. The origin of "mediums of exchange" in human societies is assumed to have arisen in antiquity as awareness grew of the limitations of barter. The form of the "medium of exchange" follows that of a token, which has been further refined as money. A "medium of exchange" is considered one of the functions of money. The exchange acts as an intermediary instrument as the use can be to acquire any good or service and avoids the limitations of barter; where what one wants has to be matched with what the other has to offer. Most forms of money are categorised as mediums of exchange, including commodity money, representative money, cryptocurrency, and most commonly fiat money. Representative and fiat money most widely exist in digital form as well as physical tokens, for example coins and notes. Overcom ...

Paperback
A paperback (softcover, softback) book is one with a thick paper or paperboard cover, and often held together with glue rather than stitches or staples. In contrast, hardcover (hardback) books are bound with cardboard covered with cloth, leather, paper, or plastic. Inexpensive books bound in paper have existed since at least the 19th century in such forms as pamphlets, yellowbacks, dime novels, and airport novels. Modern paperbacks can be differentiated from one another by size. In the United States, there are "mass-market paperbacks" and larger, more durable "trade paperbacks". In the United Kingdom, there are A-format, B-format, and the largest C-format sizes. Paperback editions of books are issued when a publisher decides to release a book in a low-cost format. Lower-quality paper, glued (rather than stapled or sewn) bindings, and the lack of a hard cover may contribute to the lower cost of paperbacks. Paperback can be the preferred medium when a book is not expected t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hardback
A hardcover, hard cover, or hardback (also known as hardbound, and sometimes as case-bound) book is one bound with rigid protective covers (typically of binder's board or heavy paperboard covered with buckram or other cloth, heavy paper, or occasionally leather). It has a flexible, sewn spine which allows the book to lie flat on a surface when opened. Modern hardcovers may have the pages glued onto the spine in much the same way as paperbacks. Following the ISBN sequence numbers, books of this type may be identified by the abbreviation Hbk. Hardcover books are often printed on acid-free paper, and they are much more durable than paperbacks, which have flexible, easily damaged paper covers. Hardcover books are marginally more costly to manufacture. Hardcovers are frequently protected by artistic dust jackets, but a "jacketless" alternative has increased in popularity: these "paper-over-board" or "jacketless" hardcover bindings forgo the dust jacket in favor of printing t ...

Audiobook
An audiobook (or a talking book) is a recording of a book or other work being read out loud. A reading of the complete text is described as "unabridged", while readings of shorter versions are abridgements. Spoken audio has been available in schools and public libraries and to a lesser extent in music shops since the 1930s. Many spoken word albums were made prior to the age of cassettes, compact discs, and downloadable audio, often of poetry and plays rather than books. It was not until the 1980s that the medium began to attract book retailers, and then book retailers started displaying audiobooks on bookshelves rather than in separate displays. Etymology The term "talking book" came into being in the 1930s with government programs designed for blind readers, while the term "audiobook" came into use during the 1970s when audiocassettes began to replace phonograph records. In 1994, the Audio Publishers Association established the term "audiobook" as the industry standard. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
