A map in Counter-Strike: Source is the playable environment where all the scenario takes place. It uses the .bsp file format. Maps are created and updated in Hammer (Source SDK). While many maps are officialy created by Valve, the majority has by far reached custom maps from mappers around the world! Everyone is always welcome to use Hammer and create maps, as long as they have a Source game.
Official maps are all the maps Valve made for the Counter-Strike series. These include de_dust, cs_assault, cs_office, de_aztec, ...
Most servers will offer these type of maps for the classic gameplay of Counter-Strike: Source.
Maps that are created by users who bought the game relative to the map. These are for example all the ze_maps, surf_maps, aim_maps, gg_maps, deathrun_maps, 35hp_maps, mg_maps, ...
To find these type of maps, you should browse in your servers window with any of these extensions. Servers will most likely offer maps of only one specific map type.
