There are three ways in which you can view the images in this collection. You may browse individual albums, you may browse the catalogs of images, or you may search the collection by keyword.

Browse the Albums

The Photo Collection is arranged in a series of individual albums. To begin select an album from the list presented on the collections page.

Once entering an album you will be provided with a short introduction followed by a table of contents. The table contains a sample image on the left, the album's sub-topic title, and a list of page numbers. To begin viewing the images, click on a page number to enter a web page that has up to twenty thumbnail images.

Click on any of these thumbnail images to view a 700 pixel-wide image that will fill most of a screen set to 800x600 pixel resolution.

Note! If your screen is set at 640x480, you will have to change the setting to 800x600 to view the full image without having to scroll from left to right. Also set your color at as high of setting as possible with 800x600 resolution.

Browse by Image Catalog

If you wish to review hundreds of images rapidly, you may wish to use the Image Catalogs. The Image Catalogs are set up to mirror the structure of the databases that are used to describe and annotate individual images. Each catalog has a set of pages that present thumbnails of the images contained in the database along with descriptions. Larger versions of the images are viewed by clicking on the thumbnails. Some of the catalogs will correlate with a specific album such as the NSSL and NURP albums. However, most databases provide imagery to a number of albums so there is not a one-to-one correlation.

Search the Image Collection

This web site supports a keyword search mechanism that allows the user to search on a term or terms . For best results, it is advisable to access the "help on searching" link prior to attempting searches.

After activating a search, a listing of URL's (Internet addresses) of individual 700-pixel-wide images, 20-thumbnail album pages, or 100-thumbnail index pages will appear. In general, those addresses closest to the top of the list will be most closely related to the requested image type.
