since returning to reloading after eight-ten years,
I've taken a more internet-centric approach. I did buy two recent manuals, but primarily for process and concepts, not data.
Then I scouted out the current official reloading data--that includes *.PDFs from bullet manufacturers like speer, and powder sites like Alliants, Winchester (now with Hodgdon), and Hodgdon.
Finally, I googled out and found appropriate reloading forums--handloads.com, for example, and I have even joined LoadData (at least for one year). However, I view any load data entry in gun forum topics with no small amount of paranoia, and I will not use it until it is verified from "official" data. That official data, BTW, may well be twenty-year, even forty-year old data from Handloader, and it is considered and weighed as well.
Then I have download and save data as appropriate, or simply print the data for inclusion into my own load data notes.
I find having ONLY the relevant data for the cartridge / bullet / at hand is smart--and since I have limited "desktop" space at the bench, I try to keep paper / junk out of the way.
