This page has some commonly asked questions.
The books that I list as having no publisher are directly offered by book distributors with no intermediate party involved. This makes the affected releases more personal but also potentially less polished.
Other identifiers like ISBN may be subject to unintended change on distributor change, may be unavailable depending on the art form, or have other limitations. Therefore, released art on ekdawn.com typically gets assigned an EKDN-ID that uniquely identifies the item.
An example for such an assigned id is EKDN-ID-72FDBFD3-754E-4DF3-A070-C66CDBB543B2.
