Calibre is a great piece of software. I am using it for Legos instructions set for my partner hobby which have over 300 paper instruction booklets. I have majority of the digital instruction sets in PDF from various sources and put them in Calibre Web for my partner to access the PDFs without needing to through the box to find it. Surely Legos have their own digital library but they only hold small pool of instructions on their sites which prompted me to use Calibre Web. It works well for him and I am happy with that.
