Reusability.Org is hosting a free, online book, The Instructional Use of Learning Objects. The book is released under the Open Publication license which means it can be redistributed for free. Nice stuff, but it is a shame that the version on the Resuability.Org site is in Microsoft Word format. Yuck.
It makes sense to put documents on the web in Word or PDF format if the document has layout features that are beyond HTML’s capabilities, but for just straight-up text like this, why bother with proprietary formats that require additional applications beyond the browser?
