I'll guess you refer to ISA, EISA, and PCI (we'll leave out MCA for this).
ISA Industry Standard Architecture
EISA Extended Industry Standard Architecture
PCI Local Bus
-The ISA is a 16 bit bus using gold finger connectors.
-EISA is physically similar, but has 16/32 bit capability. Finger contacts
are interleaved compared to ISA.
-PCI is either 32 or 64 bit, and has gold finger connectors as well.
MCA is the proprietary Micro Channel Architecture, which is found on
certain IBM hardware. they use a pin and socket connector.
All of the above can differ greatly in size (half or full length versions,
height, etc.) They normally use similar metal faceplates, and will have
standardized pinouts to a great degree.
There are books out on ISA/EISA, the standards of these date back to about
1990. The spec is published by:

The current spec is at version 2.1.1, I believe. See:
http://www.pcisig.com/
PCI is largely an Intel intiative, but PCI is in widespread use for
Workstations and PC's of many types. It is definitely the wave of the
future.
