My attention was drawn to the site by a posting in the mailing list Progressive Librarians Guild (PLG), in which the collection was characterized as "one of the world's largest archives of social protest literature".
The site mainly offers finding aids:
Literary collections
Labadie collections
Power collections for the study of scholarly communication and information transfer
History collections (here only: John Frederick Finerty Irish
Papers, 1921-1960)

The Power collection consists of:
American Society for Information Science Records, 1939-1990
John G. Gantt Papers, 1951-1973
Cloyd Dake Gull Papers, 1937-1987
George H. Harmon Papers, 1959-1985
National Commission on Libraries and Information Science Records, 1971-1991
National Microfilm Association, 1944-1989
Ruth S. Smith Papers, 1969-1986
Vernon D. Tate Personal and Professional Papers, 1928-1989
3M Filmsort Records, 1953-1976

Short title lists:
National Transgender Library & Archive (NTL&A) - serials
Audiocassette tapes collection
Single uncataloged manuscripts - correspondence
Single uncataloged manuscripts - topical

A closer look to the NTL&A:
"The NTL&A is a repository for books, magazines, films, videotapes, journals and newspaper articles, unpublished papers photographs, artwork, letters, personal papers, memorabilia, and ephemera related to the transgender and transsexual condition. The NTL&A is believed to be the largest catalogued collection of transgender-related materials in existence."

Furthermore online exhibits, among them:
The Soviet invasion of Czechoslovakia: August, 1968

Employees of Iraq's National Library and Archives are struggling to overcome the destruction wrought during the first weeks of the U.S.-led war. Many irreplaceable documents, photographs, maps, and books -- some centuries old -- were either destroyed in the fighting or were stolen in the rampant looting that followed. A vital part of Iraq's culture seems to have disappeared forever. [...]

Iraq's National Library and Archives once held records dating back hundreds of years. It held records from the Ottoman Empire, handwritten accounts of the Iran-Iraq war, and microfiche copies of Arabic newspapers going back to the early 1900s.

But many of the records are now lost forever -- destroyed in the fires and looting that beset Baghdad after coalition forces entered the Iraqi capital 15 months ago.

"We lost about 60 percent of our state records and documents -- they were either burned or damaged by water. [The lost documents belonged] to all the ministries, all departments of the state from the late 19th century up to Saddam's period. As concerns books, I think we lost some 25 percent of them, mostly rare books, the most valuable books," Saad Iskander, director-general of the library and archives, said.

He said a big part of Iraqi culture was wiped out in just the first few days of the occupation of U.S.-led forces. Some of the lost books were several hundred years old, including a 16th-century work by the ancient physician and philosopher Ibn Sina, or Avicena. To some degree, Iskander said, an important part of Iraqi history is gone forever.

Iskander said the majority of the rare books were not destroyed, but stolen, and are now being sold illicitly in markets in Iraq and neighboring countries. Most of the archives' records, maps, and photographs are gone as well. Some have been damaged and cannot be restored.

But Iskander said there is hope that alternative records of other documents remain. Librarians are looking for microfilm records, and checking to see if copies of documents may be found in archives in Britain. But even such discoveries would be small successes in the face of the massive damage the library and archives have undergone. To some degree, Iskander said, an important part of Iraqi history is gone forever.

Mazin Ibrahim Ismail is the supervisor of the National Archive. He said librarians are trying to preserve what is left of the records belonging to the Iraqi Interior Ministry. He said the documents contain files stretching from the British occupation until the 1970s.

The archive's employees show a lot of enthusiasm. But Ismail said there are few ways to save the documents from decay and parasites. "We lack the simplest means of keeping the documents,” he said. “We have only these shelves. The air-conditioning system was put in place only a month ago. Documents need a certain temperature and specific amount of light coming in. We lack all these things."

In the mailing list INETBIB there was today a little discussion (in German) on the German Open Access-like "Digital Peer Publishing License" (DPPL) provided by the Nordrhein-Westfalen Wissenschaftsministerium:
http://www.dipp.nrw.de/lizenzen/document_view

It allows commercial use but no derivative works. This is IMHO an important difference to the Berlin Declaration:

The author(s) and right holder(s) of such contributions
grant(s) to all users a free, irrevocable, worldwide, right
of access to, and a license to copy, use, distribute,
transmit and display the work publicly and to make and
DISTRIBUTE DERIVATIVE WORKS, in any digital medium for any
responsible purpose (my emphasis)

For the definition of derivative works in Creative Commons licenses it is worth noting that this definition is inspired by The Copyright Act, at 17 U.S.C. §101 (US).

The DPPL allows commercial use of the scholar's work without his consent (e.g. in licensed databases) but not that another scholar (e.g. in India) translates his article.

Frank Halisch argued that he doesn't want that other can make "Bearbeitungen" of his works.

There are good reasons to think so but the Berlin Declaration (supported by thousands of scholars) explicitely allows derivative works. Large OA publishers - Biomedcentral and PLoS - are using Creative Commons Licenses allowing derivative works (and commercial use).

If a scholar doesn't want a) derivative works and b) commercial use he cannot choose a DPPL E-journal (the reason is that DPPL allows commercial use). He is free to use a Creative Commons License (attribution, no-derivs, no commercial use). That would be Open Access too but - and that is the point for me - no OA according to the Berlin Declaration.

The report gives background information on the SEPIADES (SEPIA Data Element Set) advisory report and SEPIADES software tool. Both were developed in the framework of the SEPIA (Safeguarding European Photographic Images for Access) project, an EU-funded project that ran from 1999 until 2003. SEPIADES is a multilevel data element set to catalogue photographic collections.
