Two volumes in the N.D. Author Services [NDAS] "Independent Authors" series of instructional ebooks are now available for free [forever] through Kobo.com and BarnesandNoble.com: Author Change Notes for Independent Authors and Manuscript Format for Independent Authors.
While the direct download PDF editions are still available, adding these volumes to your ebook reader has an additional advantage.
All "I.A" publications are living documents. If and when updated with changes or new information, you will automatically receive the updated version on your device. You can note any status of updated content by looking at the copyright page. And you can even drop by NDAS and send us suggestions for content update.
Kobo and B&N links to these publications are now available in the "Bookshop"; other volumes are pending conversion to ePUB format for like distribution.
NOTE: These publications will not be made available for Kindle. Amazon so far has refused to allow free forever ebooks. Some Kindle "tablets" may be able to install purchase apps from other vendors; see if yours has such capability.
