Block IDs
These values apply to both inventory items and to blocks placed in the world. Bold entries are not available in Alpha and italics entries are not available in Classic. Entries marked with a D require additional data to fully define the block in an Alpha world. Entries marked with an I have a different ID as  an inventory item.

Item IDs
All items have values above 255, making it easy to separate the Block IDs from the Item IDs.
