ABC's is compiled of the writings of many different authors, thus letting you hear different styles and "voices" from different points of view.
Having many different manuals lets you get the different authors' perspectives, emphases andwhat one may cover lightly, another will cover in depth. Variety is good and "The ABC's of Reloading" offers it in a single volume. See if your library has several copies from different years. I hear that the ones from the '70s, '80s and '90s are better than current ones. But decide for yourself. Reading many will not be time wasted.
