A complete list of our Missing Manuals is available here: http://oreilly.com/missingmanuals/lib...
The books are not sorted by operating system or topic, though, so if you are looking for something in particular, please let me know if I can help you find it.
I see you've asked another question about our QuickBooks Missing Manual, so perhaps I've answered you there. If there's anything else you need help with, please don't hesitate to ask.
