This plugin hasn’t been tested with the latest 3 major releases of WordPress. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.



Anthologize is a free, open-source, WordPress-based platform for publishing. Grab posts from your WordPress blog, pull in feeds from external sites, or create new content directly in Anthologize. Then outline, order, and edit your work, crafting it into a coherent volume for export in several ebook formats, including PDF, EPUB, and TEI.

Many optimizations to the PDF export have been added, but resource limits on the server will always be a potential issue. Here are some tips to try if you encounter errors or white screens of death while exporting PDF:

  1. Include page breaks between parts and items. This appears to reduce the memory that the PDF classes (TCPDF) require.
  2. Change the following information in the php.ini file in the Resource Limits section. On most hosted servers, this file is in the top web directory and/or in your WordPress directory. If there is one in your WordPress directory, edit that one. If you have questions, please contact your web hosting provider.

Change the max_execution_time setting:
max_execution_time = 180;

Change the memory_limit setting:
memory_limit = 128M;

The latest release of PHP has a default memory limit of 128M, but this might not be in place on your server. Increasing the execution time (measured in seconds) can also help.
In a hosted server environment, increasing the resources Anthologize consumes could hurt performance for everyone else on your server. It might be worth consulting your hosting company before increasing these resource limits and exporting projects on a regular basis.

Cover images in ePub output.

To add your own cover images, just upload them to the anthologize/templates/epub/covers directory and they will appear as options in the export screen. Make sure they are readable by the server.

After a lengthy search for the ideal solution to my particular use case, I finally stumbled upon this WordPress plugin. From the moment I installed it, I knew it was exactly what I had been looking for.The installation process was a breeze, and the user interface is intuitive and user-friendly. Anthologize was straightforward to set up and configure.

I found Anthologize quite useful after I developed a procedure to avoid the clog on media fragments the plugin generates. 1) Don’t install Anthologize in a live instance of your website. 2) A combination of Local by Flywheel and BackUp Buddy allow me to copy my live site to my PC. 3) On the PC, I load a copy of my live site. Zip from Backup Buddy. 4) I install Anthologize from a zip file. 5) I build my project. All fragments are stored in the Local Flywheel copy. 6) Create my PDF and ePub. I use Calibre for post-processing. 7) Recreate my test/development site. Delete the Anthologize Local Flywheel copy and reload the zip file. Ergo the media library fragments are gone.

Useful for some exports and helping organizing a book structure. For TEI, you can’t change many things about the scheme, though, unless recoding the plugin.

Anthologize is an excellent plugin I used to back up my website in PDF book form. It’s drag and drop feature to build chapters and items was very easy to use and worked flawlessley. I had my posts already set up by category so it was simply a matter of dragging them into the various chapters. An excellent future enhancement to this plugin would be if it could capture comments as well. Kudos to those who spent countless hours developing this great plugin.

This plugin looks very promising (and just what I am looking for) based on the description, but it only produces files with a front page and nothing else.
