Things made to be discarded that survived anyway — tickets, menus, posters, handbills. More broadly, anything of transitory existence; in zoology, a mayfly.
No coiner. Samuel Johnson made the first recorded use of the word for printed matter in 1751, using it of the papers of the day; ephemera as a collecting category is far later, from John Lewis's Printed Ephemera (1962) and Maurice Rickards onward.
// Where it sits
And the accidental survivals often tell you more, because nobody curated them.
What it really means
Greek ephēmeros — epi + hēmera, lasting a day.
The word has had at least four careers in English, and the one everybody knows is the last of them.
It arrived in the late 14th century as a medical term: a fever lasting one day. In the 17th century it was applied to short-lived insects and flowers — the mayfly order is Ephemeroptera, day-wing. And only in 1751 did Samuel Johnson apply ephemerae to the papers of the day, the first documented use pointing at transient printed matter.
So a word for a fever became a word for a fly became a word for a bus ticket.
What makes the collecting sense worth taking seriously is the contrast with an archive, and it is a genuine methodological point rather than a nice turn of phrase.
An archive is what somebody decided to keep. Every item passed a judgement about significance — which means an archive is a record of what a particular time considered important, and its silences are as designed as its contents.
Ephemera is what nobody decided to keep, and which survived anyway. A theatre programme in a coat pocket. A price list used as a bookmark. A handbill in a wall cavity. Nothing selected these. They record ordinary life at the level nobody thought to document — what things cost, how people were addressed, what was assumed to need no explanation — precisely because no one was curating.
The accidental survivals frequently tell you more than the deliberate ones.
And the mayfly deserves a correction, because it anchors the whole word. Mayflies do not live for a day. The nymph stage can last several years underwater; only the adult is brief. In the extreme case, Dolania americana, adult females live under five minutes.
The name records the part of the life we happen to be present for — which is, in a sense, the whole subject.
One last note for the pedantic: ephemera is already a plural. A single item is an ephemeron.
Where it comes from
Ephemera is already a plural. A single item is an EPHEMERON — though dictionaries also record ephemeras and ephemerae as plurals of ephemera itself.
Myths & misconceptions
Ephemera has always meant collectible paper.
Its first English sense was a ONE-DAY FEVER. The insect and flower senses came in the 17th century, and the printed-matter sense only in 1751 — three distinct careers before it reached a collector's folder.
Mayflies live for one day, which is where the word comes from.
The NYMPH stage can last SEVERAL YEARS underwater; only the adult is brief. The extreme case, Dolania americana, has adult females living under five minutes. The name records the part of the life we happen to see.
Compare & contrast
Ephemera vs archive
An archive is what someone decided to keep. Ephemera is what nobody decided to keep and which survived by accident — which is exactly why it records what archives leave out.

| Records | Ordinary life | What mattered |
| Selected by | Nobody | Someone |
| Bias | Random | Deliberate |

- Evanescentthe word for duration's neighbour — perceptibility rather than time.

Questions people ask
- What is the singular of ephemera?
- Ephemeron. Ephemera is the plural form inherited from Greek and Latin usage, though dictionaries also record ephemeras and ephemerae as plurals of ephemera itself.
- Do mayflies really live only one day?
- Only as adults. Nymphs can live for years underwater, and the extreme case — Dolania americana — has adult females living under five minutes.
- When did it start meaning printed matter?
- 1751, with Samuel Johnson's use of 'ephemerae' for 'the papers of the day'.
