# I don't have an e-reading device, such as an e-reader or a tablet. Are they ebooks?

**Of course!** Ebooks can be read on a number of devices, including:

* A computer (PC or Mac)

* An e-reader (e.g., Sony Reader, Kobo)

* A touch tablet (e.g., iPad, Samsung Galaxy Tab)

* A smart phone.

On the other hand, it's much more pleasant to read ebooks on a device with a screen dedicated to reading, such as an e-reader or a tablet.

# Adobe Digital Editions on the Mac - Installing Adobe Digital Editions on your Mac

If you already have the Adobe Digital Editions application installed on your computer, proceed directly to [(ST2437-en) Entering your Adobe ID in Adobe Digital Editions for Mac](https://ajuda.biblioled.gov.pt/en/doc/st2625/1/entering-your-adobe-id-in-ade-for-mac.md).

The Adobe Digital Editions application lets you open ebooks on your computer or transfer them to your e-reader.

1. Determine which version of Adobe Digital Editions you need to install. To verify which version you have if you already downloaded the application:

* Open the Adobe Digital Editions application on your computer.

* Click on **Adobe Digital Editions** in the menu.

* Click on **About Adobe Digital Editions**.

* The version is indicated below the name of the application.

Which Version Of Adobe Digital Editions Do I Install?  
If you want to transfer ebooks from your computer to your e-reader, note that the latest version of Adobe Digital Editions is known to cause occasional file-opening problems with some e-readers. During the process of transferring an ebook from Adobe Digital Editions to an e-reader, an error message may appear saying that the file cannot be opened due to an authorization issue. To avoid this problem, **installing Adobe Digital Editions version 3 is recommended unless your Mac is running macOS Catalina and later versions.**

From Catalina onward, the macOS operating systems no longer support 32-bit applications. While Adobe Digital Editions version 3 is a 32-bit application, the latest version is a 64-bit application. If you have problems transferring ebooks from Adobe Digital Editions to your e-reader and your Mac's operating system is macOS Catalina (or later), you will need to install an older version of the macOS operating system, such as Sierra.

# Android (Google) tablets and smartphones startup guide

To read an ebook borrowed from your library on a tablet or smartphone that uses Google's Android operating system, follow these steps.  
Here are some tablet brands that use Google's Android operating system: Acer Iconia, ASUS ZenPad, Google Nexus et Pixel, Huawei MediaPad, Lenovo Tab, LG G Pad, Samsung Galaxy Tab.

Here are some phone manufacturers that use Google's Android operating system: Acer, Alcatel, Archos, Asus, Google, HTC, Huawei, Lenovo, LG, Meizu, Motorola, Nokia, Oppo, Panasonic, Samsung, Sony, Vodafone, ZTE.  
If your tablet or smartphone uses the iOS mobile operating system instead, go to the [(ST2437-en) iOS (Apple) tablets and smartphones startup guide](https://demarque.atlassian.net/wiki/spaces/ds/pages/465797829/ST2437-en+iOS+Apple+tablets+and+smartphones+startup+guide).

## Using the application

The application allows you to browse, borrow and read ebooks from your library all within the application itself. No file transfer is required. It supports Licensed Content Protection (LCP) DRM and not the Adobe Content Server (ACS) DRM to protect ebook files. No Adobe ID is required to use it.  
While the vast majority of ebooks are protected by LCP, some ebooks, due to their format or the distributor that supplies them, are protected by ACS. In such cases, you will need to use another application to read them (see [Reading with another application](https://demarque.atlassian.net/wiki/spaces/ds/pages/466420244/ST2437-en+Reading+using+a+different+application)).

# Why can't I change the size of the font on my e-reader or my tablet?

Books on the platform are available in one of two formats: EPUB and PDF. EPUB files are flexible in that you can change certain aspects of the layout, including font size or color. PDF files, on the other hand, are more static. Font size cannot be changed, which makes reading on an e-reader much harder, or even impossible.

# Compatible reading devices and applications

An ebook can be read on different devices:

* a computer;

* a dedicated reading device or e-reader;

* a tablet;

* a smartphone.

To read an ebook borrowed from your library, your device and the reading application you use must be EPUB and PDF compatible. They must also be able to read a DRM (Digital Rights Management) protected file. This page lists the major devices and reading applications that are compatible with e-lending.

To learn more on how to borrow and read an ebook on your device, see our [quick start guide for your device](https://ajuda.biblioled.gov.pt/en/doc/st2625/1/startup-guides.md).

What is the difference between an EPUB and a PDF?  
EPUB is an open format standardized by the World Wide Web Consortium (W3C) based on the XML language. It is designed to simplify on-screen reading. Its main advantage is dynamic reformatting, where the layout of text and images adjusts automatically when the font size is changed. This format ensures comfortable reading on any device, whether on a computer, a reader, a tablet or a smartphone.

Created by Adobe, the PDF format is now an open format standardized by the International Organization for Standardization (ISO). This format guarantees uniform layouts (fonts, images, etc.) regardless of the medium on which the file is read. PDFs offer comfortable reading on a computer and most tablets but makes reading on an e-reader or smartphone more difficult, if not impossible.

What is a DRM?  
Digital Rights Management (DRM) is a protective measure built into an ebook and designed to protect it from copyright infringement. It controls the various parameters of the digital loan, including its duration. Two DRMs are used in e-lending. To read an ebook protected by ACS (the Adobe Content Server DRM), you must have a ByteBooks account, which you can sign-up for free, and a compatible e-reading application (see [(ST2437-en) Compatible reading devices and applications](https://demarque.atlassian.net/wiki/spaces/ds/pages/465502629/ST2437-en+Compatible+reading+devices+and+applications)).The LCP DRM (Licensed Content Protection) is an open solution developed by the Readium Foundation, which includes more than 80 members of the publishing industry. If you are using the application on your iOS or Android mobile device, this is the DRM that is used.

What is the difference between an e-reader and a tablet?  
Tablets are multimedia devices that usually have most of the functions of a laptop computer. On the other hand, e-readers are dedicated reading devices. Their screen uses a display technique, called e-ink, that mimics the appearance of a printed page to lessen visual fatigue caused by reading on a screen. They are generally lighter than tablets and have longer autonomy (several days or even weeks).

### Incompatible e-readers

Amazon Kindle  
You cannot read an ebook borrowed from your library on Amazon Kindle e-readers (all models).

## Tablets and mobile devices

### Compatible tablets and mobile devices

All tablets running **Android version 5** and above or **iOS version 15** and above are compatible with the application.

*On Android, our reading applications are only available through the Google Play Store. Since Amazon has its own app store, Amazon Fire tablets do not come with the Google Play Store installed. Thus the only way to access our reading applications on these tablets is by first installing the Google Play Store manually. The installation of this third-party product is complex and falls outside the scope of this documentation.*

### Non-compatible tablets

A compatible e-reading application must be used (see [Compatible mobile applications](https://demarque.atlassian.net/wiki/pages/viewpage.action?pageId=465502640)) to read an ebook borrowed from your library on a tablet. These are downloaded from your tablet's application store (App Store on iOS, Google Play on Android). Some older tablet models do not allow you to download a compatible e-reading application. Such is the case for the following tablets:

* Chromebooks that do not support Android applications (models released before 2019)

* 1st generation iPad

* Microsoft Surface RT and Surface Go

## E-reading applications

### Compatible desktop applications
