how can I find an old picture from a Pittsburgh newspaper of the
1950-1951 and 1951-1952 Duquesne University basketball team?

Hi buntifer-ga,

What a neat question! It's not exactly a straightforward answer, but
here are several options for obtaining a copy of the photo to which
you are referring:

The Pittsburgh Post Gazette (Pittsburgh's primary paper) maintains a
clippings file from 1920s and 1930s to the present "catalogued by
topic or name, housed at the Post-Gazette offices in Downtown
Pittsburgh. The public is not allowed direct access to the
Post-Gazette's paper clipping files, but the Post-Gazette will conduct
research upon request for a fee. For more information, please send
e-mail to library@post-gazette.com or call (412) 263-1619."

Almost every newspaper ever published in Pittsburgh is available on
microfilm at the Carnegie Library of Pittsburgh's main branch in the
Oakland neighborhood of Pittsburgh. This includes the two major
newspapers of the time - the Post Gazette and the Pittsburgh Press
(since absorbed by the Post Gazette). They are the most likely
newspapers to contain the photo to which you are referring.

Here is a list of all newspapers available on microfilm at the Carnegie Library:

If you have an exact date of publication you can probably have them
look it up for you. The library also maintains aa vertical file of
newspaper clippings starting in roughly 1900 on Pittsburgh and
Pennsylvania topics in general, as well as an extensive historic photo
collection. Either of these may have the photos you want. You can
contact the Pennsylvania Room at the Carnegie Library directly for
more information on their reference services:

If they can't easily locate the photo in their indexed content (photos
and vertical clippings file) and you don't have an approximate date
(month and year at the very least), you'll either need to do this
yourself (scrolling through microfilm rolls takes a long time) or hire
a researcher to do it for you. If you don't live in Pittsburgh and
can't easily access the Carnegie library, you can borrow microfilm of
most of these newspapers through interlibrary loan from the State
Library of Pennsylvania (your local library should be able to help you
with this).

Alternatively, the Duquesne University archives has an extensive photo
collection and may have a copy of the photo you are seeking.

You can contact them directly:
Duquesne University Archives

I hope this helps to answer your question. If you have further
questions or any of this is unclear, please let me know via a
clarification request.

Best of luck in your search!
