Wolfe Publishing offers a subscription to Loaddata, an online collection of data from all kinds of sources, including the stuff published in their magazines. You can print to your heart's content and put the result in the binder they give you when you subscibe. Lots of articles too, IIRC.
Otherwise, the web is loaded with info, good and bad, and you can always buy books, including Ken Waters' Pet Loads, and the one I just got, JB's Big Book of Gun Gack. Gun Digest used to include factory load tables, but I haven't bought one of those in decades. Might have to resort to catalogs or the web for that.
