Ephemera20 began as a straightforward undertaking: to collect web addresses into a browsable index, arranged by subject rather than by popularity or algorithmic weight. The result is an open catalog, composited in the manner of a printer who sets type as it comes — in sequence, without editorial preference, one entry after another until the drawer is full. The catalog is organised into 22 sections, each corresponding to a broad area of trade or interest: automobiles, dental services, technology, travel, finance, and so on, with a miscellany section for addresses that do not fit elsewhere. Within each section, entries appear in the order they were submitted — there is no ranking, no promotion, and no fee for placement. A site submitted today will appear at the foot of its section's list, in the same position as any other new arrival. Submissions are accepted from any web address that falls within one of the 22 sections. Each submission is reviewed briefly before it is filed — the review is a light press-check rather than a rigorous editorial process — and there is no charge to list. The catalog is open to businesses and individuals alike. Ephemera20 takes its name from the printer's term for small, incidental printed items: the handbills, labels, tickets, and notices that accumulate at the edges of the press run. The catalog is maintained in that spirit — a collection of incidental addresses, gathered without grand purpose, useful to those who know what they are looking for and sometimes surprising to those who do not. The index is not connected to any search engine ranking product and makes no claims about the visibility or authority of listed addresses. It is, simply, a directory: type set in order, filed under headings, left on the shelf for the reader to browse.
