The Encyclopedia of Life, No Bookshelf Required
By CARL ZIMMER

Imagine the Book of All Species: a single volume made up of one-page descriptions of every species known to science. On one page is the blue-footed booby. On another, the Douglas fir. Another, the oyster mushroom. If you owned the Book of All Species, you would need quite a bookshelf to hold it. Just to cover the 1.8 million known species, the book would have to be more than 300 feet long. And you’d have to be ready to expand the bookshelf strikingly, because scientists estimate there are 10 times more species waiting to be discovered.

It sounds surreal, and yet scientists are writing the Book of All Species. Or to be more precise, they are building a Web site called the Encyclopedia of Life (www.eol.org). On Thursday its authors, an international team of scientists, will introduce the first 30,000 pages, and within a decade, they predict, they will have the other 1.77 million.

While many of those pages may be sparse at first, the authors hope that the world’s scientific community will pool all of its knowledge on the pages. Unlike a page of paper, a page of the Encyclopedia of Life can hold as much information as scientists can upload. “It’s going to have everything known on it, and everything new is going to be added as we go along,” said Edward O. Wilson, the Harvard biologist who spearheaded the Encyclopedia of Life and now serves as its honorary chairman.

Other experts not involved in the project hail it as tremendously promising. “I certainly think it is a great idea,” said Jody Hey, a biologist at Rutgers University.

Yet a number of researchers wonder if it will reach its final goal. The encyclopedia is not the first attempt to catalog every species on the planet, and previous efforts have failed. “I have seen 20 years of good ideas go nowhere,” said Daniel Brooks, a University of Toronto biologist.

Dr. Wilson has been involved with some of those failed attempts. But in the past few years major advances in databases have made the goal more realistic. Today biologists can consult databases that hold DNA sequences from hundreds of thousands of species, for example. There are also more detailed databases about groups of species, like mammals, fungi and parasites. In 2003, Dr. Wilson wrote a paper in which he called for all that information to be available in one place.

He and his colleagues then persuaded the John D. and Catherine T. MacArthur Foundation to contribute money to a consortium of universities, museums and scientific institutions. The Alfred P. Sloan Foundation and some of the partners are adding money as well. The encyclopedia will have a budget of about $50 million in its first five years.
