Please, be smart, there is no use if you scan covers in 600 dpi (exept it was 4 times bigger)! Scan it in 300 or max. 350 dpi. I am graphic designer and believe me I know what I'm talking about
Btw. same is with audio files ... 16-bit/48 kHz is enough (just look what ECM or ACT are capable of!). There is nothing better in 24-bit/96 kHz or 24-bit/192 kHz! This is all marketing tricks for untutored
And, yes, thanks again for your effort!
