Link collections of conferences, workshops, and summer schools which are related to the NLP/CL field. The label P which follows each year/conference is linked to the online proceeding.You can find another information at http://perun.si.umich.edu/~radev/u/db/acl/. Also, some of the online proceedings can be found at ACL anthology which you can follow from ACL web site.
