We have searched the Lynds 988 dark cloud complex for optical (\ha{} and\sii{}) and near-IR (\mh{} 2.12 $\mu$m) shocks from protostellar outflows. Wefind 20 new Herbig-Haro objects and 6 new \mh{} shocks (MHO objects), 3 ofwhich are cross detections. Using the morphology in the optical and near-IR, weconnect several of these shocks into at least 5 distinct outflow systems andidentify their source protostars from catalogs of infrared sources.  Two outflows in the cloud, from IRAS 21014+5001 and IRAS 21007+4951, are inexcess of 1 pc in length. The IRAS 21007+4951 outflow has carved a large cavityin the cloud through which background stars can be seen. Also, we have found anoptical shock which is the counterflow to the previously discovered "northwestoutflow" from LkHa 324SE.
