We established GRIN to help journalists, publishers, educators,
authors and the general public find high-quality historical
photos. Photos were selected both for their historical importance
and their visual impact. This is a large collection and understanding
how to browse GRIN efficiently will save you a lot of time.
We intend GRIN to be easy and fast to use, and to complement
the NASA Image Exchange (NIX). GRIN has been designed in accordance
with the Section 508 Guildelines. GRIN is also completely accessible through the use of Access Keys. For help on this subject, view Access Keys for GRIN.
There are numerous ways to browse GRIN. The primary methods
are by Subject, Search, and NASA Center.
The Subject method is probably the most useful and
straightforward way to browse GRIN. There are 93 separate
categories of GRIN images. We have tried to anticipate the
kinds of images that professionals and the public will want
and divided the images into these categories. Many GRIN images
are in more than one category. But some images are specifically
confined to a single category for ease of searching.
To see a brief description of what the subject categories
include, see the Explanation of Subject
Categories. Note that some categories are empty or nearly
empty. We anticipate adding more images to these categories
in the future.
The Search function is also an efficient means of
locating images provided that you understand how it works
and use it to your advantage. We suggest using the search
function:
-
if the subject you are searching for is not already
one of the existing subject categories;
-
if the subject category of interest is too large for
your purposes, or;
-
if you are looking for something very specific.
Please note: The search function treats multiple words as
if they are separated by "or" not as if they
are separated by "and". In other words, typing in
"lunar rover" will give you every entry with the
word "lunar" and every entry with the word "rover",
including many entries that contain only one of these words,
such as a photo of a Mars rover. By placing your words in
parentheses, the search engine will treat them as if they
are separated by "and". So "(lunar rover)"
will narrow the search considerably.
When using the search function, keep in mind that the more
specific you can be, the faster you will find what you want general
search words like "moon" will produce too many hits
to be useful. Also, searching only in specific fields may
be faster. In particular, searching in the Keywords category
may be most useful, since we have already narrowed the search
for you. Keywords can also include other helpful info, such
as the old names of NASA centers, such as Lewis before it
was renamed John H. Glenn Research Center.
The final method of searching GRIN is by using the NASA
Center search function. Many of the images in GRIN come
from some of the recent books produced about the NASA centers,
so if you have one of these books, there is a good chance
that the images inside are contained in GRIN. Some of the
centers (like Stennis) only have a few dozen images, whereas
others (like Johnson, Langley, and Kennedy Space Center) have
hundreds, so this method will be more useful in some cases
than others.
