All of Earth's known species to be cataloged on Web site

In a whale-sized project, the world's scientists plan to compile everything they know about all of Earth's 1.8 million known species and put it all on one Web site, open to everyone.

"It's an interactive zoo," said James Edwards, who will be the encyclopedia's executive director. Edwards currently helps to run a global biodiversity information system.

The effort, called the Encyclopedia of Life, will include species descriptions, pictures, maps, videos, sound, sightings by amateurs, and links to entire genomes and scientific journal papers. Its first pages of information will be shown Wednesday in Washington where the massive effort is being announced by some of the world's leading institutions. The project will take about 10 years to finish.
