After close to 50 years of accumulating lyrics/with chords (first handwritten, then typed, then finally on computer) plus fake books, sheet music, etc., my case of books became unmanageable.
My first laptop saved my back and my sanity. It took nearly a year to convert everything to computer, but now all my lyrics with chord changes are on there. They are on my laptop, two home pcs, and several external drives.
They are in Word format, text format and OO format.
One of the best things I ever did was to write down the lyrics and chords to every song I ever played (well almost).
Now with my android phone and laptop I have constant internet access and often download a song on the job and play it.
Of course then I have to go home and learn to play it right.
Probably 80 percent of the songs I do regularly I don't look at anything except the whites of their eyes, or other parts of their anatomies, depending on the visual excellence. Sometimes I pretend I'm looking at the keys because if I don't they think I'm not really playing.
