Browsing to see what images are available

To see if an image is available for downloading, go to You can then browse image thumbnails by period, author and date. Click any thumbnail to view an image in a larger format.

The image server contains the following different resolutions of each image:

  • Thumbnails;
  • 5-inch jpgs that load quickly in a web browser;
  • 10-inch jpgs that show more detail when previewed in a web browser or displayed in a presentation;
  • High resolution images in tiff format suitable for printing. These images are too large to preview in a web browser or to use in a presentation.

For example, let's suppose you are looking for an image of the title page of Astronomia nova (1609) by Johann Kepler. Images are sorted according to : Period / AuthorName / Publication Year / FileName.

  • Period: All of the works of an author are grouped according to the century of the first major publication. Kepler's first major publication was Mysterium cosmographicum (1596); therefore images from all of Kepler's books are found under the 16thCentury. Similarly, modern editions of Euclid's Geometry are found under ancient Greek science.
  • AuthorName: Among the 16thCentury links there is a link for Kepler.
  • PublicationYear: Among the Kepler links you will find links for each of his books, named according to the year of publication. Other links may exist for portraits from our collection of 6,000 portraits, or for travel slides, exhibits, maps or other kinds of related items. Click these links to browse thumbnail images. Click any thumbnail to view a larger version.
  • FileNames: File names typically include the author's name, the year of publication, the volume number and page number, and a suffix indicating format (.jpeg, .tiff, .mov, .pdf). Abbreviations used within file names include fp (frontispiece), tp (title page), c (colophon), bk (the book as a whole), pl (plate), v (volume). A zero is usually inserted before fp and tp images to help them sort at the top, before other pages.

Therefore, the file named Kepler-1609-0tp.jpg should be what we're looking for. After previewing the image in a jpg format, you can download the corresponding high resolution tiff version, Kepler-1609-0tp.tif.
