We have an enhancement pending to provide [...]

Bookworm on MacBreak Weekly

This week Bookworm was featured as part of a great discussion on ePub in the MacBreak Weekly Podcast (it’s the last topic in the podcast).
Naturally, Bookworm was down.
(It was a brief outage that — ha ha — was necessary to improve the reliability of the site.)
Many thanks to Andy Ihnatko for the plug. [...]

dc:identifier in wild ePubs

Here’s some trivia about the use of the required dc:identifier metadata element in ePubs that have been uploaded to Bookworm to date.

The Tim O’Reilly bump

(Bookworm traffic before and after Tools of Change keynote. More metrics)

Bookworm is now part of O’Reilly Labs

I’m extremely pleased to announce that the Bookworm project is now part of O’Reilly Labs.
Like many software engineers, I learn best by building. Bookworm began as my way to learn the ins and outs of the ePub ebook format. Thanks to the growing adoption of ePub and integration with other products like Stanza, Bookworm now [...]

The new [...]

Bookworm survey results

I was disappointed to receive only 10 responses to the recent Bookworm poll, but four of those included thoughtful “other” answers and the response I expected to win did not.
The question was:
Which feature would you be most interested in seeing added to Bookworm?

Edit title, author and other metadata in your ePubs and export that to [...]

Quick ePub check

If you’re producing ePub files, take the time to ask yourself two simple questions:

Are all the files I listed in the OPF file actually in the ePub archive?
Are all the files in the archive in the OPF file?

The OPF file is meant to be the canonical listing of all resources in your ePub.  If it’s [...]

One-question survey for Bookworm users

Bookworm now has an active community of users. I’d like to know what features people are most interested in seeing added to the service.
If you are so inclined, please take this very quick one-question survey on which single feature you’d like to see in Bookworm:
What’s next for Bookworm?
I’ll post the results in a week [...]

Stanza integration has tripled Bookworm’s traffic

This graph compares books-added-per-day from the period after Stanza integration (in blue), to the same duration immediately preceding it (in green). It’s especially impressive given the holiday dips around Christmas and New Year’s. I expect next week’s traffic to be even higher.
On average, the rate of books added has tripled, and Bookworm now hosts [...]
