These days, with the many forms of electronic readers (Kindle, Nook, etc) many interesting and useful astronomy books are available for free on the Internet and can even be attached to these pages for others benefit. It is worth noting that both of these appliances (Kindle and Nooks, maybe others?) have free readers that can be downloaded and installed in home computers - one doesn't have to buy the appliance to take advantage of the many free books out there. |
