This collection is divided into four series: Trans Health; Philadelphia City Hall; Events; and Other Materials. The Trans Health files are dated from 1996 to 2005 and include documentation from the Trans-health Information Project (TIP) and the Trans Health Action Coalition. The TIP documentation is comprised of copies of outreach session agendas and materials; administrative reports, and comprehensive medical guides written by Singer himself.

The Philadelphia City Hall series contains items dated from 1996 to 2004, which primarily deal with organizations that the Trans-health Information Project worked with on a wider scale. Documentation about the mayoral LGBT Advisory Board's Transgender work group, along with a local transgender needs assessment, are in this section. Administrative items from Prevention Point are included within this section.

The Events series of this collection has items dated from 1997 to 2007, which are about notable events: conferences, such as handouts from the first through sixth Philadelphia Trans Health Conference; film festival reviews and petitions; and a folder of photos from a gathering for the Transgender Day of Remembrance.

The final series, Other materials, collects those items that did not fully fit underneath the other three schemas. The items within are dated from 1994 to 2005 and encompass a wide spectrum. Within this group are files from casual social events like the Gay Games or HIV/AIDS support groups, or then-contemporary news articles such as Leslie Nelson's 1955 trial. In addition are Singer's copies of more personal correspondence with the all-female Sadism/Masochism community Female Trouble regarding his membership status as a transgender man, and several issues of S/M magazines.
