FAQ ePUB

In the following, you will find a list of FAQ for the usage of ePUBs.

If you cannot find the answer you are looking for in this FAQ section, please do not hesitate to contact our Customer Service at service@degruyter.com anytime.


 


What eBook format is most appropriate for my eBook reader?

eBooks are offered by De Gruyter in two different formats: in PDF format, and starting with 2014 titles, also in ePUB format.
If you ordered your eBook in ePUB format from De Gruyter, this format is not proprietary and can be read on all eBook readers that support the current ePUB format (Version 2.0). Please note that on older eBook readers the display of the ePUB fixed-layout format can be limited or even impossible to view.

What are the main differences between the two eBook formats?

eBooks in ePUB format can be adjusted to the screen size of the specific eBook reader given that there are no page numbers. The advantage is that the display can be adjusted to individual reading preferences, for example by increasing the text size. Different eBook readers display font types, font sizes, and colours differently. The PDF version, on the other hand, maintains a standardized display on different reading devices and screens. The PDF version mirrors the printed version of the book. The font types, font sizes and the layout cannot be adjusted. Please note that eBooks in PDF format can be ordered in chunks, on a chapter level, while eBooks in ePUB format can only be purchased as a whole and can be downloaded  via the "Download" button on the product pages of the De Gruyter Online website.

Are there further differences between the EPUB formats?

There are two different display options in the ePUB format. The "Fixed Layout" is better for displaying images, drawings and other graphics   Single pages are displayed separately (one-by-one). Search results will be shown on a separate page and not directly in the text. The "Reflowable Layout" is better for displaying text. The body of the text can be changed, depending on the reading device used. The text body can be altered to some extent (font-type, font size, layout) and elements can be better nested (for example URLs). Search results will be shown directly in the text. Whether De Gruyter offers the "Fixed Layout" or "Reflowable Layout" depends on the title itself.

The "Fixed Layout" ePUBs follow the Apple Standard. About two years ago the IDPF released a standard  for "Fixed Layout" ePUBs that has now become part of the ePUB2 standard.  Unfortunately at this time this standard is not supported by all eBook readers. Please note that the display of Fixed Layout ePUBs may not be optimized to your specific eReader device.

Can I choose the specific ePUB format?

No. De Gruyter decides what ePUB format is most suitable for each digital publication. At the time the ePUB is downloaded it is not apparent if it is a "Reflowable" or a "Fixed" ePUB format.

What are the technical specification of the EPUB format? Is there any detailed information available?

In order to offer the current features of the "Reflowable" ePUB format, the ePUB 2.0 version and the idpf standard are used. Detailed information can be found here.

What devices best display the ePUB format?

Good display results of the "Reflowable" format can be found on Apple products with the use of iBooks, with the Amazon Kindle, and in general on platforms that support the Adobe Digital Edition SDK.

"Fixed" formats are best displayed on Apple products. The usage of other devices can lead to problems, since the ePUB 2-Standard is not yet available on all reading devices.
