Free e-Learning books

Since I am a great fun of open source software (Open Source Authoring Tools for e-Learning, Free and Open Source Web Conferencing Tools for e-Learning) and active member of online communities I created the following list with free e-Learning books.

Facebook for e-Learning

Facebook objective is "to help you connect and share with the people in your life". At the same time, Facebook is one of the fastest growing social networks that helps people communicate efficiently with their friends, families, coworkers, and classmates.

• 50% of Facebook's active users log on to Facebook in any given day. 
• Average user is connected to 80 community pages, groups and events. 

Some of them are your learners and they know how to use Facebook effectively! Using Facebook for e-Learning could inspire many of our students to learn. As a result, my question is how can we use Facebook for e-Learning?
 

Free and Open Source Web Conferencing (Online Meetings, Webinars) Tools for e-Learning

I received several emails, message on Twitter, and InMails on LinkedIn concerning the Open Source Authoring Tools for e-Learning and the Free Stock Photos Sites for e-Learning blog posts. Guys the most of you find these posts a valuable resource for the the e-Learning community. As a result, the 3rd blog post is Free and Open Source Web Conferencing (Online Meetings, Webinars) Tools for e-Learning.

The following list contains free and open source Web Conferencing tools that are n't in particular order.

Also, you should be sure that the e-Learning community will highly appreciate:

1. if you post a comment with your experience with these tools and/or,
2. if you post a comment with a link to any other free and open source Web Conferencing tool.
