The joy of finding an old box in the attic filled with postcards, invitations, theater programs, laundry lists, and pay stubs is discovering the stories hidden within them. The paper trails of our lives -- or ephemera -- may hold sentimental value, reminding us of great grandparents. They chronicle social history. They can be valuable as collectibles or antiques. But the greatest pleasure is that these ordinary documents can reconstruct with uncanny immediacy the drama of day-to-day life. The Encyclopedia of Ephemera is the first work of its kind, providing an unparalleled sourcebook with over 400 entries that cover all aspects of everyday documents and artifacts, from bookmarks to birth certificates to lighthouse dues papers. Continuing a tradition that started in the Victorian era, when disposable paper items such as trade cards, die-cuts and greeting cards were accumulated to paste into scrap books, expert Maurice Rickards has compiled an enormous range of paper collectibles from the obscure to the commonplace. His artifacts come from around the world and include such throw-away items as cigarette packs and crate labels as well as the ubiquitous faxes, parking tickets, and phone cards of daily life. As this major new reference shows, simple slips of paper can speak volumes about status, taste, customs, and taboos, revealing the very roots of popular culture.

Vols. for 1853- include the transactions of the Royal Photographic Society of Great Britain.

Wht's bttr thn crsswrds? Tht's rght: crsswrds wth n vwls! At first, these challenging, but fiendishly fun, puzzles look like the usual crossword. But there's a devilish twist: you write only the consonants in the boxes, "not" the vowels. So when you look at the grid, there's no quick way to know exactly how many letters make up the right solution. Plus, because you don't need as many spaces for each word, the phrases can be longer than usual--and that makes the grids wide open and ratchets up the difficulty level. For those who need a little extra help, there's a hints section to tear out and refer to when needed, as well as grids with wordlists explaining (with vowels) what the answers are.
