Up to date information about protocols for alternative tests to animal testing are maintained in the INVITTOX database, which is maintained, updated and disseminated by ECVAM as part of the databases at the Scientific Information Service (SIS) of ECVAM. The full protocols are hosted by ECVAM only.
For a quick first look (but not for the actual protocols), you can look at the list available on this site (but this list has not been updated recently):
a copy of the protocols as published by SIS/ECVAM in August 1999. This list contains 124 protocols, organized around topics.
the same list as the one above, but the protocols are organized numerically (and in PDF format).
