There are a number of much easier ways to manage and add blocks now than block libraries.
I keep all our Typical blocks in a drawing called Typicals. With this BLOCKSPALETTE (Command) macro anyone I work with can pick and insert whatever typicals they need.
Code:
^C^C-blocknavigate;"G:/ENGDESGN/BeaufordT/Blocks/Typicals/Typicals.dwg";_blockspalette
Building, adding or modifying the blocks in a drawing is a piece of cake, doesn't require rebuilding a library and displays the blocks exactly how they will appear when inserted, much better than you ever could with a block library.
Another method that's been around a while is using the ADCNAVIGATE (Command) in a macro.
I have a drawing with blocks of all the MUTCD road sign blocks. This macro displays all those sign blocks in Design Center with their names.
Code:
^C^C^P(command "adcnavigate" "G:/ENGDESGN/BeaufordT/Blocks/MUTCD.dwg")
Tool Palettes are another way to handle this we didn't have for much of AutoCAD's history.
I taught an ATP class here on AUGI on Customization that covered creating block libraries back in 2003. Before AutoCAD was upgraded to 32 bit there was a download that made creating and editing block libraries easy. Haven't used them in years though.
AutoCAD really does improve with every version. Embrace all the upgrades they've made to the interface, don't become a dinosaur.
