8. 6. Configurable Opening Position

The excerpt will open at the position (landmark)
that publishers already set for retailers such as
Amazon, Apple, Kobo, etc.
Or can be set by publisher via the Jellybooks
Candy portal.
Bypassing front-matter creates a better user
experience leading to higher engagement and
improved conversion to book purchases.

9. 7. Easy to Produce

The samples, previews and excerpts are created
by Jellybooks from ebook master files distributed
by Ingram Coresource, Faber Factory, Bookwire or
uploaded through the Jellybooks Candy portal.
The process fits into existing workflows and
requires no additional work by publishers.
Excerpts are provided through an API to
publishers for automated inclusion in product
pages, content management systems (CMS) or
similar.
The platform is automated, future-proof,
affordable and very cost effective.

10. 8. When to use PDF
• When you need an EXACT replica of the print book layout (for
booksellers, authors, agents, etc. rather than actual readers).
• When you need a version with an exact match to the print
pages for reference purposes (academic researchers and
reference systems) though you could also consider using
fixed-layout (FXL) ePUB to achieve the same effect.
• When your require a version that end-users can print out on
their home or office printer.
...in all other cases ePUB wins out!

Book previews, excerpts, and samples enable consumers to
digitally browse your titles.
They often provide the hook in the online consumer journey from
discovery to purchase
With 68% of users globally now accessing a website from a mobile

across a range of devices, including smartphones, is now vital.
To work effectively online excerpts have to be easy to read and
available on any device with a minimum of effort. ePUB is the
clear winner here!
