Other Resource for Vanilla instance and raid guides?

[Gossamer]

Does anyone know of a good resource for instance guides for all of the low level dungeons in addition to the endgame dungeons and raids? Most of the versions seem to be for the post-Cata content.

You can check the older versions of pages on Wowpedia. If a dungeon or raid has been redone (Naxx, Ony, ZG, BFD, VC etc), you can use Dungeonname (Original) to find the original version. The only difference for dungeons that were not changed is some dungeons had their levels changed (All DM dungeons, Scholo and Strath got reduced to 35 - 45 for example), and boss hp got upped 10x in Cata. It should note the level change in the Patch Notes section. One of the nice things you'll find on wowpedia are official dungeon maps Blizz put in.

Here's a couple:

If you're checking older versions of the article, make sure they're dated before October 2010 (when the first prepatch for Cata went live).
