Networked Computer Science Technical Reference Library
NCSTRL (pronounced "ancestral") is an international collection of computer science research reports and papers made available for non-commercial use from a number of participating institutions and archives. Some of the documents in NCSTRL are part of the technical report collections of participating institutions. For the most part, NCSTRL institutions are universities that grant PhDs in Computer Science or Engineering, with some industrial or government research laboratories.
