The web already contains a lot of information about the IL-14; No website would be complete without references to this information. For technical details I suggest wikipedia (IL-14) in the first place until I am able to provide better information here. I want to keep expanding this list, so let me know if I have left something useful out.
- IL-14 in Orlovka: IL-14 Restoration Project
- If you want to, you can order the CIA Instruction Manual: CIA Manual on IL-14
- Polish exhibition of IL-14S with 360 degree fotos
- The Pacific Coast Museum in Santa Rosa has an former Polish executive version on display, labelled il-14 crate
Other relevant sites about historic Aircrafts, but not IL-14 in particular
