Digimon Reference Book

The Digimon Reference Book, previously named Digimon Dictionary, is a subsection of Digimon Web focused on providing both the official names and profiles of Digimon which include ones that were never released on any of Digimon Web's other subsites or in general. The site was launched on June 25, 2007 and has since been usually updated every week with the addition of two new profiles. However, since April 6, 2012, only one profile has been added a week. As of August 17, 2012, there are currently Category:Digimon with profiles on Digimon Reference Book Digimon pages available on the Digimon Reference Book. =Structure=

Categorization
Profiles are categorized in two different ways and can be viewed accordingly upon the viewer's preference. They are listed alphabetically, subdivided into ten sections. This system is also incorporated in the URL of a Digimon's page:

They are also listed by evolution stage:

As of June 4, 2010, a new subcategory was added for Digimon introduced in Digimon Xros Wars. The sections for Armor and Hybrid Digimon were added on April 27, 2012.

When new profiles are added, they are indicated by having the word " NEW!! " temporarily placed to the left of a Digimon's name until a new set of profiles are unveiled. Originally, there was also a field that listed the year a Digimon was active from, however although there were a few Digimon listed with given dates, namely those that were added near the time of Digimon Reference Book's opening, this seemed to cease when newer, more recent profiles were released. With Digimon Web's revamp in June 2010, the year field was removed entirely.

Naming
Digimon names labeled with the X-Antibody affix retain the same name as their counterparts, labeled merely for distinction and not amalgamated into its main name - e.g Greymon X-Antibody's name is "Greymon" as opposed to "Greymon X-Antibody". Similarly, the same situation applies to the majority of recolors, i.e those of subspecies, and level changes.

Images
While the majority of the images are displayed in high quality, with a standardized size of 320 x 320 pixels, for a brief time - between April 18 and June 6, 2008 - there were a number of images released that were below the current standard. Although the quality of images released prior to this returned to normal, with the exception of two pages (Labramon and Ancient Volcamon), the remaining low quality images still exist on their pages.

Profiles
Languages

The profiles of Digimon whose counterparts are affected by the X-Antibody retain the format of pages displayed on the Pendulum X site. The overall profile is a combination of the original profile of the precedent followed by its own.

General syntax:
 * Original profile
 * Ｘ抗体による _______ のデジコアへの影響 (The effect on _______'s Digicore due to the X-Antibody)
 * X-Antibody counterpart's profile 

Example of an X-Antibody counterpart's profile (Vademon X-Antibody): Digimon Reference Book 遠い宇宙の果てからやって来たような姿の宇宙人型デジモン. しかし、植物の実から生まれたという噂がある. 巨大に発達した頭部と、タコのような下半身からは想像できないが、恐るべき攻撃力を身に付けている. 手に持っている光線銃から発射されるアブダクション光線も脅威だが、必殺技『悪魔のなげキッス』は敵をフヌケにしてしまう恐ろしい技だ. ■Ｘ抗体による ベーダモン のデジコアへの影響 “ 不良宇宙人”. 一説では地球侵略のためにやってきたベーダモンだが、逆に地球の文化に影響されてしまった姿が表れている. 自分はより強く進化していると考えているが風貌だけであり、サングラスも本当は見え難い. しかし、敵のデジモンを脅すコツを身に付け、地球侵略のために一歩近づいたのかもしれない. 微笑みながら敵の足元を蹴る『天使のローキック』は、敵を逆上させてしまう恐ろしい技だ.

Following the 2011 Tōhoku earthquake and tsunami, a few profiles were shortened. More specifically, all mentions of earthquakes and tsunamis were removed. Independent of that, information has also been removed from some other profiles, such as translation aids for attack names. See Digimon with updated profiles on Digimon Reference Book for a list of altered profiles.
