Ebooks (sometimes eBooks or e-Books), as its name implies, are digital text based documents or works that serve as an electronic alternative to traditional, physically printed publications. Typically, they are optimized for [[E-book reader| Ebook readers]] but there are plenty of desktop and mobile applications that can read them.

The first envisioned ebook (and ebook reader) was a project called DynaBook which conceptualized by Alan Kay, the creator of one of the first and very influential object-oriented programming language called smalltalk and the one who coined the term object oriented programming, to be used for education and similar environments. Unfortunately, the project was scrapped.

E-Books come in a variety of formats so its pretty important to know them and their characteristics.

== IDPF ==
International Digital Publishing Forum is an organization created to standardize electronic publication and foster global adoption of an open, accessible, interoperable digital publishing ecosystem. This relieves the stress of publishers that want to release an ebook having to figure out which format to use and which reader to support. IDPF along with its file formats have since been absorbed into W3C (World Wide Web Consortium) which manages web technologies and standards such as HTML, XHTML, CSS, Javascript, XML, WebRTC, WebGPU, Wasm, and more.

Comic Book Archives technically aren't formats on their own. It describes a loose family of file formats which are ultimately just a collection of images in the usual image formats like PNG or JPG and commonly an optional XML file for metadata compressed into a single archive. The last character changes and it denotes which compression archive it uses. Comic Book Archives are the preferred format for many comic book, manga, bandes dessinees, manhwa, and manhua enthusiasts.

Due to the popularity of Amazon, Kindle ereaders, Kindle store, Kindle Unlimited, Audible, Goodreads and more, Amazon has a firm grasp over the ecosystem of book readers. They prefer using their own format which is usually based on an existing format to lock users in as well as keeping out competitors. Despite the fact that they own Comixology, Kindle remains pretty much the last modern reader without support for Comic Book Archives.

Even after AZW came out in 2007 and AZW in 2011, it was still well supported.

Ebooks (sometimes eBooks, EBooks, or e-Books), as its name implies, are digital text based documents or works that serve as an electronic alternative to traditional, physically printed publications. Typically, they are optimized for Ebook readers but there are plenty of desktop and mobile applications that can read them.

History

The first envisioned ebook (and ebook reader) was a project called DynaBook which conceptualized by Alan Kay, the creator of one of the first and very influential object-oriented programming language called smalltalk and the one who coined the term object oriented programming, to be used for education and similar environments. Unfortunately, the project was scrapped.

Formats

E-Books come in a variety of formats so its pretty important to know them and their characteristics.

IDPF

International Digital Publishing Forum or IDPF is an organization created to standardize electronic publication and foster global adoption of an open, accessible, interoperable digital publishing ecosystem. This relieves the stress of publishers that want to release an ebook having to figure out which format to use and which reader to support. IDPF along with its file formats have since been absorbed and now under the leadership of W3C (World Wide Web Consortium) which manages web technologies and standards such as HTML, XHTML, CSS, Javascript, XML, WebRTC, WebGPU, Wasm, and more.

OEB

  • OEB - IDPF's first format using HTML, XML, and optional stylesheet.

ePUB

  • EPUB / EPUB 2 - OEB 2.0 was renamed EPUB as it varied greatly from the previous format. So EPUB and EPUB 2.0 are the same thing. It now uses XHTML instead of HTML and supports CSS.
  • EPUB3 - Comes with many modern changes over 2.0. It now has HTML 5 and CSS 3 support. It attempts to move away completely from XML. Bookmarks now use XHTML instead of XML in the .ncx file.

  • AZW3 - Amazon's answer to the aging MOBI format. Like MOBI, it retains some remaining Palm elements like the database but the text itself is now based on EPUB instead of PalmDoc.

Comic Book Archives

Comic Book Archives technically aren't formats on their own. It describes a loose family of file formats which are ultimately just a collection of images in the usual image formats like PNG or JPG and commonly an optional XML file for metadata compressed into a single archive. The last character changes and it denotes which compression archive it uses. Comic Book Archives are the preferred format for many comic book, manga, bandes dessinees, manhwa, and manhua enthusiasts.

.cbr
Comic Book Archive compressed into RAR.
.cbt

.cb7
Comic Book Archive compressed into 7z.
.cba

Kindle Family

Due to the popularity of Amazon, Kindle ereaders, Kindle store, Kindle Unlimited, Audible, Goodreads and more, Amazon has a firm grasp over the ecosystem of book readers. They prefer using their own format which is usually based on an existing format to lock users in as well as keeping out competitors. Despite the fact that they own Comixology, Kindle remains pretty much the last modern reader without support for Comic Book Archives.

AZW

KF
Kindle Format
  • AZW - Based on MOBI which itself is extended from PalmDoc. Basically the same thing but with better compression and different DRM scheme. Has been deprecated in favor of AZW3 and AZW4.

Has a free, GPL'd implementation called DjVuLibre created and still maintained by Léon Bottou himself. The Intellectual Property of the original format is dormant bouncing around various software companies and hasn't been developed on since it left Bell Laboratories.
