ePub eBook

EPUB is a free and open e-book standard by the International Digital Publishing Forum (IDPF). Files have the extension .epub.

An EPUB file can optionally contain DRM as an additional layer, but it is not required by the specifications. In addition, the specification does not name any particular DRM system to use, so publishers can choose a DRM scheme to their liking. However, future versions of EPUB (specifically OCF) may specify a format for DRM.

There are a variety of options for publishers who want to create digital editions. Some vendors provide a high service model, where publishers can simply send a pdf and detailed instructions to their vendor. The vendor then creates the digital edition from scratch and provides a high quality product the publisher can offer its readers. Unfortunately, high service comes at a high price. This kind of vendor is ideal for a company with a big budget and no time to get involved in creating a digital edition.

.acsm to epub/pdf

I download epub and pdf format books from the public library and a private bookseller.  The download comes with a .acsm suffix instead of epub or pdf. When I try to transfer these to my Nook Color use ADE they are not accepted by ADE and do not show in the library window.

How can this problem be solved?

A. When you borrow a ebook from public Library, what you are really downloading is an .acsm file. There is a lot of confusion about this file type as the .acsm is not your actual eBook. It is just a link to your eBook that allows a program like Digital Editions to download the actual book, When Digital Editions sees the .acsm file it will automatically download the PDF or ePUB file, which is the actual eBook,
If you do have Adobe Digital Editions installed and authorized correctly, then you won’t even see the .acsm file at all. It will do its job in the background of your ebook download. The purpose of this file is to communicate with Adobe’s content server and register the ebook to the Adobe ID that you have used to authorize ADE. If you don’t know how to do the authorization process, so you only remove drm from epub/pdf file, not from .acsm file, This is how to remove drm from epub/pdf file.

What is an .acsm file?

ACSM stands for Adobe Content Server Manager. That name gives a clue as to the purpose of these files — they are download manager files. They manage the download of your ebook.

The majority of the time, you don’t even see the .acsm file when you download an Adobe ebook. Usually the only time you see it is if you haven’t properly set up Adobe Digital Editions, or you don’t even have it installed. I can’t stress this enough: before you buy Adobe ebooks, whether PDF or EPUB, install the software you need! If you haven’t installed the correct software for any file type, your computer won’t know what to do with it.
