I hate to burst anyone's bubble, but those guys are a sham. They basically publish whatever gets sent to them in "special edition" hardcopy volumes, and offer to sell them to the poets who enter their contests.

They flatter the entrants and then offer to have their poems included in a cassette with special readings, mounted on a special plaque, etc... all for hefty fees.

Last time I checked up on these guys, someone was purposely trying to send in bad poetry to see if it would get rejected, but they weren't rejecting any.

Also, as of last time I checked, they still have one of my poems on their website somewhere, though I asked for it to be removed several years ago.

Just a heads-up. Take the National Library of Poetry with about a metric ton's worth of salt.
