Since 1890 the DVOC has published a record of birding in the Delaware Valley. The first four publications were "Abstracts of Proceedings of the Delaware Valley Ornithological Club of Philadelphia". Since 1900 the publication has been called Cassinia.

The DVOC is committed to the long term goal of making all volumes available on-line. This project will be accomplished as time and resources are available.

(Up to Volume XLIX [49], roman numerals were used to designate the volumes. Beginning with Volume 50, arabic numbers were used)

Several indexes are available for the Abstracts and Cassinias. Entries for Number 1 (1890-1891) to Number 63 (1988-89) were prepared by Frank and Barb Haas, Bob Mercer and Chris Dooley at the time of the 100th anniversary of the Club. These indexes have been updated to Number 70 (2002-2003) by Lynn Jackson.
