Surely I am not the only person who not only keeps every databook I've 
ever owned, but also buys old databooks (I think I have a pre-1970 
Motorola IC databook somewhere -- back then one book covered all ICs 
;-)). 

Databooks are _esssential_ if you want to understnad or repair the hardware!

And sometimes a machine's service manual will assume you've got the docs 
for an older model.
