Registration 35th IPH Congress
Investigating American Collections on Paper
June 7-11, 2021

The International Association of Paper Historians (IPH) is pleased to open registration for its upcoming 35th Biennial Congress on June 7-11, 2021. The much-anticipated event, entitled "Investigating American Collections on Paper" will be co-hosted by the Library of Congress, the National Gallery of Art and the National Archives and Records Administration. The Washington DC organizers have transformed the original in-person Congress into an online colloquium that will enable greater participation by paper historians, scholars and students from around the world.

The Congress will open with a keynote address from the eminent paper historian John Bidwell, Astor Curator and Head of the Department of Printed Books and Bindings at The Morgan Library & Museum in New York, and will feature talks given by 35 other outstanding international scholars. Presentations will cover a wide variety of topics, including the international paper trade from the 17th century to the present; technical studies of papers used by artists such as Leonardo da Vinci, Albrecht Durer, Pablo Picasso and Jasper Johns; early handmade papers imported, fabricated and used in North, Central and South America; historical papermakers' equipment; papers used in incunabula, illustrated books and manuscripts, including those associated with the First US Federal Congress; papers used by the Inuit printmakers of Canada and the print publisher Currier & Ives.

Presenters will also discuss international watermark databases, new methodologies of paper studies, and toolkits for paper and watermark identification. In addition to the pre-recorded formal presentations with live question and answer sessions, workshops will allow participants to gain greater familiarity with watermark imaging tools and international watermark databases, guided by their creators. The IPH Congress 2021 offers an unprecedented assembly of experts available for interactive discussion.

Beginning in late May 2021, registered participants can view the pre-recorded presentations at their convenience on the conference website. The live Congress week, June 7-11, 2021, will be devoted to dialogue between registered participants and speakers in live question and answer sessions. The Congress week will also include live workshops on watermark databases and short videos from the host institutions. The IPH Business Meeting, for IPH members only, will be held on June 11, 2021.

We had all looked forward to meet each other in 2020 at the national paper-historical conferences during the summer and in the autumn at the 35thInternational IPH Congress in Washington, DC — the second IPH Congress in United States in 60 years. The brilliant 2020iph local organizing committee had planned everything in details, but all meetings and cultural events had to be postponed to 2021. The program of the 35th IPH Congress in Washington, DC will in this New Year for the first time in the history of IPH be presented on a virtual platform, followed online all over the world by the speakers and congress participants with interest in the history of paper.

In IPH we have in spite of restrictions, isolation and closed frontiers been in contact with each other as usual via emails, phone calls and letters. Through online meetings in 2020 we have learned that it is possible to discuss and plan together, continue research projects and publish articles of the research in periodicals and books. Online meetings, conferences and congresses will take place in the New Year, but before the end of 2021 we can look forward to meet each other again in person. The increasing numbers of new IPH members during the last two years illustrate the growing interest in the history of paper, in studies of watermarks, paper trade and technology and how to preserve the cultural heritage of manuscripts, prints and drawings in collections and libraries through conservation, restoration and storage of the paper.

On behalf of IPH I send all of you my best wishes for a peaceful and happy New Year, where I look forward to meet you at the 35th IPH Congress in Washington, DC on the virtual platform in June 7-11, 2021.

Anna-Grethe Rischel
President of IPH
