"Ksenia, [I] have a .doc file that was set up for print [that I] want to convert to an ebook. Saw some stuff about converting it into a PDF but [is] that really the way to go? Should it be a different file type? Want it to be read on most devices."

Jim, it's funny how converting text to an ebook is such a non-brainer to me now that I don't even think it could be a hassle when you're self-publishing. It certainly was when I started, and I was lucky enough to find Stuart Whitmore of Crenel Publishing who formats all my books, which is waving a magic wand (he totally has a magic wand, I'm sure) and making flimsy capricious Word files into nice sturdy PDFs and EPUBs and MOBIs. Which are really the only three formats I use for my ebooks: PDFs for free downloads on my site and on sites like Scribd and to submit to CreateSpace; EPUBs and MOBIs for free downloads on my site and for sites like iBooks (they accept EPUBs) and Amazon (they accept MOBIs for Kindle or they convert your PDF to MOBI for you). So. Here is the truth.

I DO NOT CONVERT TEXT INTO EBOOKS MYSELF.
