From the website of the builder and designer, Dirk Nelson:
Nelson had collected a treasure trove of Walla Walla valley history … Among the collection were beams & bolts from the old Louisiana Pacific mill to enormous light poles from the Columbia River’s McNary Dam. Railroad trestle girders lay stacked beside huge locust tree wood taken from the actual home site. With meticulous hand work, Nelson and his team, Living Space Construction transformed the boneyard finds into structural components that each hint at the story of their former lives.

John Calvin was a man of the book in every possible sense. First, he lived his life in an uncompromising manner by the Book … Second, he was a humanist and scholar who, living through the birth of modernity, not only depended on the printed word to inform his ideas, but also used the opportunities presented by the invention of the printing press to disseminate his thoughts and reflections to a world that was primed for change. Third, he helped to shape the history of the book itself. … Of all of the sheets of print produced by individual writers in the period from 1541 to 1565, Calvin is responsible for an astonishing 42% of the total …
Because he lived and wrote, Christianity has been forever changed; the political structures of the West have been permanently altered; even the economic realities by which we order our lives have been shaped by the vision that he and his disciples had of humanity’s place in creation.
According to this YouTube video, an estimated four exabytes “of unique information” will be created this year—“more than the previous 5,000 years.”
Some years ago, to confront the challenges of managing and preserving large amounts of data generated over decades of space missions and observations, NASA’s Consultative Committee for Space Data Systems created the reference model for Open Archival Information Systems (OAIS).
A helpful introduction to this 148-page document is available here:
Unlike many standards, OAIS specifies no particular implementation, API, data format, or protocol. Instead, it’s an abstract model that provides four basic things:
- A vocabulary for talking about common operations, services, and information structures of a repository. ... [see section 1]
- A simple data model for the information that a repository takes in (or “ingests”, to use the OAIS vocabulary), manages internally, and provides to others. … [see sections 2 and 4]
- A set of required responsibilities of the archive. … [see sections 3 and 5]
- A set of recommended functions for carrying out the archive’s required responsibilities. … [see section 6].
Building on this model, in 2002 RLG-OCLC released a report on Trusted Digital Repositories: Attributes and Responsibilities, which was followed in 2007 by the RLG-NARA Trustworthy Repositories Audit & Certification: Criteria and Checklist. A number of institutions at present are working to become trusted digital repositories.

A bag is like a folder or directory on a computer. It is essentially comprised of three elements: A bag declaration text file, which is like a seal of authenticity; a text-file manifest listing the files in the collection; and a subdirectory – usually titled “data” – filled with the digital content. The manifest is machine readable for automated data ingest. The receiving computer analyzes the manifest and runs checksums on the contents; if the checksums match, the transfer is successful.

From the Declaration of
He has called together legislative bodies at places unusual, uncomfortable, and distant from the depository of their public Records, for the sole purpose of fatiguing them into compliance with his measures.
A history of this record is available here.
