How to get my brother's poems heard?

[classmate]

There are lots of magazines that publish poetry. The book "Poet's Market" (your local library might have a copy) has information about how to submit poems to many of those magazines. You can also find information at this site:

You're sweet to be so supportive of your brother's writing, but you and he should brace yourselves for some of the harsh realities of the publishing world. The best poetry magazines get tons of submissions and publish only a tiny fraction of the poems that people send to them. If your brother is seriously interested in having his stuff published in reputable magazines, he should do a lot of reading. (And I mean a LOT. He should read at least 100 poems by published authors for every one poem that he writes himself.) The more good poetry he reads, the better his own writing will get, and the more he'll improve his chances of getting published.
