Q: Lost I Tunes libary after factor reset

Due some minor/major problems after non use for some months,the I Tunes libary was lost / hidden  somewhere? I have looked up many many websites regarding this but nothing works,I can not find any screens showing anything. even my Ipod.I have connected the Ipod to my laptop but no screens appear to ask me import the tunes.I had to do a factory reset to get things working properly after the laptop was not used for a long time.I keep printing paper but the more I print the more I get a little confused.I would say the I Tunes libary was working alright just before the new year and also the ipod.Can anyone help.it may be a simple answer or something more complicated!Thanks.
