Welcome to Automatic Ephemera, a library for historical research and education, sharing public domain documents relating to vintage products for
the home. You are viewing the low-resolution preview, high-resoultion versions are also available for most documents.
The scanning of all high-resolution documents is done at 300dpi with the utmost diligence and care to produce high quality .pdf files which have text
search capabilities built-in to bring modern convenience to vintage printed materials.
The high resolution also allows for close-up examination of all images on your computer monitor and in many cases makes
reading the text easier than the original document. Quality printers can print these documents nearly identically to the original document. Maintaining a library as such is a
time consuming and expensive venture, all materials have a small download fee to offset the library's many expenses.
