sure you can on all of the ereaders go back there is usually an option called go back and using that you can go back to any page or any chapter etc, there are a few options that would let you go back, you can bookmark pages you think you will want to go back too and then you simply choose the bookmarks list and pick the ones you want to go back too.

that is how it works on any of the ones that are android based I think kindle has similar options.

there are many ereader programs so each one has it's own options but that is usually one of the basics.

any time you go anywhere it will save the last page you were at but if you worry it might not then just click to book mark that page so you know you can always go back to it by using the bookmarks list.
On one of my tablets if it happens to die from the battery going dead while I am reading it sometimes does not save my page that I was on so on that one I will bookmark pages as I go if I know my battery is low.

Thanks so much passed the info on to DS

Another question
What if I have a file (like in WORD) on my computer that is long can I load it onto a Reader and read from that?

depends on the unit and what type of content it can access, some do some don't. you need to look at the specific unit you are interested in and see what content formats it can handle. Most can do PDF files. You could also convert the word file to a format that could be used in some cases.

You can send personal documents to your Kindle as an attachment to an e-mail (your Kindle will have it's own e-email address - username@Kindle.com - which is based on your Amazon account), and Kindle's "Personal Document Service" will convert them to a compatible Kindle format. Currently, the types of documents you can send are:

Microsoft Word (.DOC)
Structured HTML (.HTML, .HTM)
RTF (.RTF)
JPEG (.JPEG, .JPG)
GIF (.GIF)
PNG (.PNG)
BMP (.BMP)
PDF (.PDF)
Microsoft Word (.DOCX) is supported in the experimental category.

There is a 15-cent per MB charge for this, but if you don't want to pay the fee, you can e-mail them to username@free.Kindle.com and the converted document will be sent to the e-mail address that you use for your transactions with Amazon (where they send you your order confirmations, shipment notices, etc.). Then, you can transfer the document from your computer to your Kindle using the USB cable.

Oh, about sending PDF documents to your Kindle -- if you send a PDF as an attachment to your Kindle e-mail address, the document will be received still in PDF format (yeah, I know that's redundant - Portable Document Format format). But, if you want the PDF document converted to a "regular" Kindle document, put the word "Convert" as the subject line of the e-mail.

Thanks for all the info I'll copy it to a file and study it
Thanks again
