E PUBLISHING MODELS TA: Hend AlHedaithy

Types of E Publishing Models 1.Commercial e publishing 2.Print-on-demand (POD) 3.Subsidy e publishing 4.Self publishing.

1) Commercial e publishers: Commercial e publishers choose to publish books that are most likely to be sold – a good mix of quality and subject matter is what they look for and rejection rates are pretty high. While their websites serve as effective storefronts, they also sell through other online bookstores like Amazon.com etc.

2)print-on-demand (POD) Another interesting model is the “print-on- demand” (POD) model, which is a mix of electronic and print publishing. The book is held by the publisher in electronic form and is printed out in the hard copy form only on order.

3) Subsidy Publishers: Subsidy e publishers differ from commercial publishers in several ways. For one, they accept most manuscripts and publish them on an “as is” basis. These are not edited or proofread or even formatted. They have a virtual rate card for add-on charges for these services, should the author opt for it. Everything, from adding images or graphics to copyright registration, is offered at add-on rates.

4) Self publishers: These are authors who choose to publish their e book on their own and in the bargain earn hundred percent revenues and keep all publishing rights. The main idea is to avoid the publishing, marketing, licensing costs and keep complete control over the design, price and marketing strategy.

2D Barcodes and Mobile Tagging

What is barcode? A barcode is an optical machine- readable representation of data relating to the object to which it is attached. Originally barcodes systematically represented data by varying the widths and spacings of parallel lines, and may be referred to as linear or one- dimensional (1D).

What is barcode? Barcodes were not commercially successful until they were used to automate supermarket checkout systems, a task for which they have become almost universal. Their use has spread to many other tasks that are generically referred to as automatic identification and data capture (AIDC).

2D Barcode Later, barcodes evolved into rectangles, dots, hexagons and other geometric patterns in two dimensions (2D). Although 2D systems use a variety of symbols, they are generally referred to as barcodes as well.

Barcode Reader Barcodes originally were scanned by special optical scanners called barcode readers. Barcode reader is an electronic device for reading printed barcodes. It consists of a light source, a lens and a light sensor translating optical impulses into electrical ones. Additionally, nearly all barcode readers contain decoder circuitry analyzing the barcode's image data provided by the sensor and sending the barcode's content to the scanner's output port.

Barcode Reader later, scanners and interpretive software became available on devices including desktop printers and smartphones.

Barcode Use Barcodes have become a ubiquitous element of modern civilization, as evidenced by their enthusiastic adoption by stores around the world. Almost every item from a grocery store, department store, and mass merchandiser has a barcode on it. This helps track items and also reduces instances of shoplifting involving price tag swapping.

Barcode Use They are widely used in the healthcare and hospital settings, ranging from patient identification (to access patient data, including medical history, drug allergies, etc.) to creating SOAP Notes. They can also be used to keep track of objects and people; they are used to keep track of rental cars, airline luggage, registered mail, express mail and parcels. Barcoded tickets allow the holder to enter sports arenas, cinemas, theatres, fairgrounds, and transportation, and are used to record the arrival and departure of vehicles from rental facilities, etc.

Barcode Use Some 2D barcodes embed a hyperlink to a web page. A capable cellphone might be used to read the pattern and browse the linked website.
