The technical stuff - aide memoir
A very simple summary of electronic archiving principles:
- keep all content under one Root URL to aid crawling/indexing;
- internal links should be relative (not absolute);
Scanning: 600 dpi for photographs (or better); 300 dpi for printed back-ups of documents (OCR may demand more detail). If space allows, keep close to these parameters when publishing to the web - but use compression formats (JPEG) to ease the experience of visitors as they load pages! If anyone wants a higher quality image, they can usually ask for it.
For particularly important images: use non-lossy formats like TIFF G4 Compression. Although this is not usually suited to web-publishing.
Physical documents and photographs - use acid-free (paper/card) and non-reactive (e.g. plastics) storage - both in terms of the containers that make contact with originals and the larger containers in which folders, pockets, and loose documents are stored.
