This is taken directly from the Writer Beware site:
Below is a list of the 20 literary agencies about which Writer Beware has received the greatest number of advisories/complaints over the past several years.
None of these agencies has a significant track record of sales to commercial (advance-paying) publishers, and most have virtually no documented and verified sales at all (book placements claimed by some of these agencies turn out to be “sales” to vanity publishers). All charge clients before a sale is made–whether directly, by levying fees such as reading or administrative fees, or indirectly, for editing or other adjunct services.
Writer Beware recommends that writers avoid questionable literary agencies, and instead query agencies that have verifiable track records of sales to commercial publishing houses.
Note that while the 20 agencies listed here account for the bulk of the complaints we receive, they’re just the tip of the iceberg. Writer Beware has files on nearly 400 questionable agencies, and we learn about a new one every few weeks.
