Restoring a library using the ipod

Question

I recently lost all my files due to a virus, including itunes, when i reinstalled Itunes my library had gone and whenever i plug in my ipod it only gives me the option to transfer the new library to my ipod.
Is there any way i can get all the songs on my ipod and put them back into my library?
Thanks in advance, and sorry if this is simpley solved, im new to it.

"whenever i plug in my ipod it only gives me the option to transfer the new library to my ipod"
As your iPod is set to update automatically you just need to take care when connecting back to your computer and an empty iTunes. When you get the message that your iPod is linked to a different library and asking if you want to link to this one and replace all your songs etc, press *No* (or "Cancel" if you are using iTunes 7). Pressing "Yes" (or Erase and Sync in iTunes 7) will irretrievably remove all songs from your iPod. Your iPod should appear in the iTunes source list from where you can change the update setting to manual and use your iPod without the risk of accidentally erasing it. In iTunes 7 check the "manually manage music and videos" box in Summary then press the Apply button. Don't uncheck Sync Music it will be unchecked by default when you choose the manual setting: Managing content manually on iPod

You can't sync or drag your non iTMS music back directly from an iPod to iTunes. The transfer of non iTMS content is designed by default to be one way from iTunes to iPod. However there is a manual method of accessing the iPod's hard drive and copying songs back to iTunes on Windows posted in this thread: MacMuse - iPod to iTunes
If you prefer something more automated then there are a number of third party utilities that you can use to retrieve the music files and playlists from your iPod, this is just a selection. Have a look at the web pages and documentation for these, they are generally quite straightforward. You can read reviews of some of these here: Wired News - Rescue Your Stranded Tunes

The transfer of purchased content has recently been introduced with iTunes 7, look under under File>"Transfer Purchases from iPod". A paragraph on it has been added to this article: How to use your iPod to move your music to a new computer
Whichever of these retrieval methods you choose, keep your iPod in manual mode until you have reloaded your iTunes and you are happy with your playlists etc then it will be safe to return it auto-sync again. I would also advise that you get yourself an external hard drive and back your stuff up in case you have problems again. External drives are comparatively inexpensive these days and you can get loads of storage for a reasonable outlay.
