Series I contains the thirty-six images comprising the photographer's series Memorial Wall. The photographs are all black and white, silver gelatin 11x14" prints, and show memorials for people who died during the World Trade Center collapse on September 11, 2001. Many show public and private memorials to firefighters. Others show more public memorials, such as a fence where memorial tiles were hung. All the photographs were taken in 2001-2002.

Series II contains three photographs of New York City, which date from 1977 to 2002. Two black and white images from 1977 and 1990 show New York street scenes from the Lower East Side. A color chromogenic type C print, taken in 2002, shows a replica of the Statue of Liberty being transported from the roof of the Liberty Storage Warehouse on West 64th Street to the Brooklyn Museum of Art.

The series holds a portfolio, in its original case, of 10 gelatin silver prints, all numbered as 12/20 and signed by the photographer, Irwin Silver. Includes opening text with titles and dates of the works, with a statement of the project's background and purpose. The photographs were taken from 1975-1978, and the text written and portfolio produced in 1979. The container list includes the titles as documented in the portfolio.

The series includes 57 gelatin silver photographs from Irwin Silver's project Nightwalks. These black and white photographs from 1979 to 1990 are of subway entrances, storefronts, entrances to corporate buildings, street scenes, and other images of New York City (mostly Manhattan, but some Brooklyn, Bronx, and Queens) as they appeared to the photographer in the late night and early morning hours. The container list identifies all the photographs in the series with the photographer's description. The series also includes a document written by Irwin Silver in which he reflects on the project generally and on the context of some of the specific photographs.

101 color 8x10 inch photographs of Central Park scenes. The photos are undated, but in his transmittal the donor/photographer noted that they dated from 1991-1994, with most taken in 1991-92. The photographs are of both the park's natural elements (foliage, rock formations (including detailed close-ups of rock textures and colors), lawns, waterfalls, lakes/ponds) and built environment (statuary (including Alice in Wonderland), bridges (including Bow Bridge), fountains (including Bethesda), lampposts, walkways, benches, roads, gazebos). Familiar sites (Bethesda, Alice in Wonderland, Bow Bride) are represented, but most of the views are of the more typical general views of park features. Certainly not typical of the park is that the photographs are notably devoid of people and animals, even at popular spots such as the Mall and Belvedere Castle), thereby focusing on the park itself. The photos also include several that include the buildings just outside the park, with the park's features as foreground. All four seasons of the year are represented so many photos capture the park in the white of snow and in autumn colors, as well as the lush green of summer and the color of spring blooms.
