Do PHIL images represent the most current scientific methods practiced in the field of public health?
Answer: The imagery showcased in the PHIL is historic in nature. The contents depicted, though appropriate
at the time a photograph was captured, may no longer be appropriate in the context of the current time
period, and is not to be viewed as a source of the most current public health information.
I am having trouble viewing the PHIL web site. What's wrong?
Answer: The PHIL is a sophisticated web application and requires a
high-end computer for optimal performance. It is designed for 17-inch monitors
with display settings of at least 800 x 600 resolution and at least 16-bit
colors. A screen resolution of 1024 x 768 pixels is recommended.
How do I run a search on the PHIL?
Answer: The PHIL offers two basic searches common to the Internet
environment: Quick Search and Advanced Search.
- Uses "keywords" which are embedded in the textual description of the image record
Image Type (Photos/Illustrations/Videos)
- Click the drop-down menu that reads "All Image Types"
Select from the choices
- Photos Only
- Illustrations Only
- Videos Only
- Or allow the default "All Image Types"
"Add to Search" feature allows additional keywords to be applied to the
results of a search in order to narrow the results even more. All the keywords
involved are listed to the right of "Selected Keywords," which appears on the
screen above the search bar. This feature is activated by clicking the "Add to search" checkbox.
"Image ID Search" is available to users who know specific identification numbers of images
- Clicking the text opens search box
- Enter PHIL ID #. Multiple IDs must be separated by a single typing space
- Click "Search"
- Allows a user to control the same search elements as in the "Quick Search" with the addition of "Category Search," and "Date Range" choices for both "Creation Date" and "Upload Date," and keyword choice within specific FIELDS of a record's metadata.
- "Image Type" allows users to specify whether or not they want ONLY "Public Domain" images in their search results or wish to see BOTH "Public Domain" AND "Copyright Restricted" images, for example. The same is true for the "Color" versus "Black & white" choice. Users may also choose the format type: "Photos," "Illustrations," or "Video" or all of them together (the default).

"Category Search" features:
- A controlled vocabulary viewable as a "tree" showing hierarchies of terms branching out from the top-level terms, "People," "Places," and "Science."
- Click "plus" and "minus" signs to open or close hierarchical levels
- Select terms by clicking the check box before each term; the selection will be marked in "red"
- The "gray" box indicates no images were catalogued under that specific term. (There could still be images catalogued under a term's sub-categories.)
- Click "Search" button in lower right hand corner of page
- To change selections in the same hierarchy, simple click the "Clear Selections" link in the upper right-hand area of the "Category Search" section of the page
- To collapse the hierarchical tree structure to start over, click "Reset Trees"
How do I view search results in PHIL?
Answer: There are three custom views you that you can select whether
in "Quick Search" or "Advanced Search" mode. Each allows viewing 10, 15, 25, or
50 items per page.
The different views and their key features are:
- Thumbnail (Default) - thumbnail image with identifying PHIL Number (ID#) and "Add to Download" selection box
- Detail - thumbnail image with ID #, description, and date
- Full - Larger thumbnail image with complete metadata
The user controls the view and the number of images per page by clicking
"Custom Results View" on both the "Quick Search" and "Advanced Search" pages.
The number of pages in a given search result are listed individually at the
bottom of the page in order from 1 to 10. For results that yield more than 10
pages, the additional pages are grouped by tens. If a search, for example,
yields 15 pages, they will be numbered
Results Page: 1 2 3 4 5 6 7 8 9 10 11-15

What regulations govern the use of images in the PHIL?
Answer: Images are either "Public Domain" (free use) or "Copyright
Protected" (restricted, obtain permission before use)
Top of Page
Most of the images in the collection are in the public domain and are thus
free of any copyright restrictions. If you look directly beneath the image you
will see a fair use statement that tells you if the image is public domain or
Permission is not required for public domain images, but we do ask that you
credit the original institution and contributor, when known, whenever the image
is used in any publicly distributed media.
If the image is copyright protected, you will have to contact the content
provider to obtain usage permission. PHIL does not have the authority to grant
usage for any copyrighted images in the library. If you have difficulty
contacting a content provider, we may be able to help, but we cannot act on

Is a statement required when using photographs in conjunction with sensitive topics?
A "sensitive use disclaimer" is required when a PHIL photograph is used to accompany a written passage
describing a sensitive, or controversial topic, i.e., sexually-transmitted disease, mental health issue, which is unrelated
to the person, or persons identifiably depicted in the image. A number of PHIL photographs depict models, who
had posed for these images merely to reflect the lifestyle-related activities portrayed therein. When you chose to
implement this type of photograph, the phrase, "Stock photo. Posed by model.", is required.
