Good point. Sometimes Bundle of Holding has neat stuff that I haven't seen on the Far Future web site, notably a collection of GURPS Traveller titles that were handy to have in PDF. (Sometimes print is handier, but sometimes PDF is handier.)
I particularly liked having a digital copy of Behind the Claw – it's nice to be able to print the entry for a player character's home world to attach to the character sheet; before I had it, I photocopied it, which was a hassle. It would be a bit less hassle today, because I have a multi-function printer that can do copies, but printing from PDF is still easier. (Digressing further, I know there are some wacky things in Behind the Claw, but I can ignore the parts that don't make sense, like inconsistencies with population codes – on some worlds, the population codes include bases, while on others they seem to disregard them.)
