答案

the creators will use information from scientific databases(数据库)that already exist.And eventually, in special sections of the site, non-scientists with specialized knowledge will come to help. Bird-watchers, for example, will be able to input what birds they‘ve seen and where. To make sure the encyclopediaew Roman'">)that is accurate, scientists will review much of the information added to it

因为这段,业余爱好者只是提供一些有用的信息给数据库,然后在由scientists去审查验证（review)之后,才把那些信息加入百科全书的数据库.
