After a suggestion from Tom Scheinfeldt at foundhistory.org, I've decided to release my open-content monograph, "How to Write a Zotero Translator" as a print on demand book for those who prefer a paper version. The book was originally released as an open-content website by the Network in Canadian History & Environment and is still available on their website.
As Dr. Scheinfeldt rightly pointed out, sometimes it's nice to have a tangible copy that doesn't compete for screen space with your coding work. The book is available for $11.99 through Lulu.com.
The content of the print on demand is the same as what's available on the website, so it's up to you to decide which you prefer.
I'm happy to report that several people in a broad range of countries have used the guide to create translators, including some for foreign language sites. If you have used the guide to help you create a translator, please let me know!
