The latest eBook from the eLearning Guild is Tips for Producing and Managing Flash-based e-Learning Content. There seems to be eight ebooks there dating back from 2005 and they are all free to download.

Each book is a collection of tips and they cover topics from choosing the best LMS (learning management system) to tips on being an online tutor.
