Issue #100 is our milestone thirtieth-anniversary issue on the theme of friendship, rivalry, and collaboration. Cover art (with 100 gloves) is by Marianne Lettieri. Inside: Shane McCrae on Louise Glück and loneliness; Padraig O Tuama on longing for home; Molly McCully Brown and Susannah Nevison on the poems that grew out of their friendship.

Plus: interview with A.E. Stallings and Adrianne Kalfopoulou on friendship, activism, and poetry; poems on friendship by Luci Shaw, Rodger Kamenetz, and Erika Meitner; fiction by Gina Ochsner; Melissa Range and Christopher Beha on their top ten books of the past thirty years.
