Symposium 2023 - October 2023

The Institute for Analytical Philately (IAP) announces that its fifth symposium will convene virtually on October 10 and October 17.

While originally planning to host the symposium in person, the IAP decided to follow the format of its 2020 symposium and have all speakers deliver their papers online. This will allow us to admit more participants than if we held the meetings in person.

The symposium's first session will begin at 10 AM EDT on Tuesday, October 10, 2023. Five speakers will address attendees throughout the day, ending at about 3 PM. The second session will start at 10 AM a week later, October 17. Five speakers will present papers that day.

Most presentations will address aspects of color in philately. Topics will include the use of Raman micro spectrometry, color analyses of various stamps, results from video spectral comparator (VSC) analyses and more. While several presentations are technical in nature, most of them should be understandable by non-scientists.

The IAP will publish the papers prior to the symposium and make them available to institute members and symposium attendees. Cost of the publication is $20 to United States addresses, $30 to foreign addresses, payable through PayPal or by check. Checks payable to "Institute for Analytical Philately" can be mailed to Bruce Marsden, IAP Treasurer, 6685 Cuttalossa Road, New Hope, PA 18938.
