Is summer a time that you have more time for your writing - and to mail off poems for publication?
Poet Diane Lockward has again posted on her blog a useful, updated list (in 3 parts) of print journals that read during the summer and some that read only during the summer.
A - F
G - P
Q - Z
Unfortunately, there aren't links to the journal sites or addresses, so you'll have to do some of the work for yourself!
