The AAEC Editorial Cartoon DigitalCollection at McCain Library and Archives
Vic Runtz’s spontaneous and charming feline character symbolizes the unique role of the editorial cartoonists who are the eagle-eyed observers, documenters, and reporters of current events. This unique perspective is one feature in particular that is so special about the Association of American Editorial Cartoonists (AAEC) Editorial Cartoon Collection housed in the McCain Library and Archives at the University of Southern Mississippi. The collection, part of the University Library’s special collections, consists of the original artwork of approximately 6,500 editorial cartoons from over 200 cartoonists who have been or still are members of the AAEC
Renovating and Expanding Special Collections Facilities at Towson University
In order to provide the university archives at Towson University with more space, the Library undertook a renovation of the archives. This article provides a brief history and overview of the Library and archives and details the renovation project which included some eco-friendly changes
What does an archivist do?
By definition, an archivist is an individual responsible for appraising, acquiring, arranging, describing, preserving, and providing access to records of enduring value1. A record is a written or printed work of a legal or official nature that may be used as evidence or proof. It is data or information that has been fixed on some medium; that has content, context, and structure; and that is used as an extension of human memory or to demonstrate accountability. Records are often created or received in the course of individual or institutional activity and set aside (preserved) as evidence of that activity for future reference2
Ultra-Broadband Coherence-Domain Imaging Using Parametric Downconversion and Superconducting Single-Photon Detectors at 1064 nm
Coherence-domain imaging systems can be operated in a single-photon counting
mode, offering low detector noise; this in turn leads to increased sensitivity
for weak light sources and weakly reflecting samples. We have demonstrated that
excellent axial resolution can be obtained in a photon-counting coherence
domain imaging (CDI) system that uses light generated via spontaneous
parametric down-conversion (SPDC) in a chirped periodically poled
stoichiometric lithium tantalate (chirped-PPSLT) structure, in conjunction with
a niobium nitride superconducting single-photon detector (SSPD). The bandwidth
of the light generated via SPDC, as well as the bandwidth over which the SSPD
is sensitive, can extend over a wavelength region that stretches from 700 to
1500 nm. This ultra-broad wavelength band offers a near-ideal combination of
deep penetration and ultra-high axial resolution for the imaging of biological
tissue. The generation of SPDC light of adjustable bandwidth in the vicinity of
1064 nm, via the use of chirped-PPSLT structures, had not been previously
achieved. To demonstrate the usefulness of this technique, we have constructed
images for a hierarchy of samples of increasing complexity: a mirror, a
nitrocellulose membrane, and a biological sample comprising onion-skin cells
