This collection consists of ALL released stories in all the formats available (ebooks, audiobooks and comics) from The Dark Tower series.
Organized in chronological order, properly named, chapterized*, tagged and of the highest quality I could find.

Alternative narrator versions are included where available. Including those narrated by Stephen King himself. As far as I know, all versions are here. If any are missing I didn't find them.
The collection does NOT contain books that have a connection, but are not themselves part of the series. (e.g. 'Salem's Lot etc.)
*The audiobooks are all chapterized in the boarder sense of the word, because the books don't have a traditional chapter by chapter structure. There are separate files for chapters, but not for the parts within.
This an updated reupload. Added The Little Sisters of Eluria audiobook.
