Paper cuts suck, but don't confuse Papercut Zine Library with the pesky lacerations it's named after. The Somerville space is actually a treasured resource for anyone who's nostalgic for simpler times, when self-publishing was about something more than vanity and profit. The library -- which offers up access to over 14,000 underground publications with topics ranging from alternative agriculture to zines about zines -- needs your help.
