Books

A Guide to Corkscrew Collecting – Published in 1993 by Peter Coldicott.  This book is an excellent quick read for the beginner collector.  It deals with the very questions new collectors are puzzling with.  Still available – ISBN 0-9521110-0-4

Corkscrews and Bottle Openers – Evan Perry’s Book was one of the very first publications and is into its second or third printing.  A very nice little book that all collectors will appreciate.  Shire Publications Ltd. still has them, mine says £1.50 but today that is more. Shire Album #59 – ISBN 0-85263-534-6

Korkenzieher – Heinz ten Doornkaat’s Book is in German, unfortunately.  A nice effort that adds some appreciation to the German collecting community.  The book is not too deep technically, well illustrated, but not too useful to the English speaking collector.   Published as an Ellert & Richter Album.

Corkscrews of the Eighteenth Century – Bertrand Giulian’s Book is arguably one of the best researched and written two or three books in corkscrew collecting.  This book covers the first generation of corkscrews, the hand made iron pieces.  A well worth acquisition for anyone.  Published by WhiteSpace Publishing, 1995, Library of Congress Catalog #94-60765 and can be ordered by Fax from the Author: (717) 737-5623 or via e-mail: giulian@kp.net

Corkscrews for Collectors – The Watney and Babbidge is “The Bible” of corkscrew collecting.  It is in its second printing, so it is available and a collector must have one of these.  A well written and researched book, and while it has some errors, based on discoveries after the time it was published, no corkscrew collector can be without one, it is well worth your while to read.  Published by Sotheby Parke Bennet, 1981  ISBN 0 85667 113 4

German Corkscrew Patents (Second Edition) – Ferd Peter’s Book is a collection of German corkscrew patents.  His interest in German pieces is the foundation of the work he produced here.  Copies are available from the author, click FP.

Scandinavian Corkscrews – The Berntson and Ekman Book focuses on corkscrews and knives of Scandinavian origin.  It is the definitive book on these Nordic pieces.  Copies are available from the authors by e-mail: collecteum@telia.com.   Published by Tryckeriförlaget, ISBN 91-970081-7-6

American Corkscrew Patents – In 1993, Nicholas D’Errico published a good book on American Patents from 1921-1992.  This Book has now been superseded by Fred O’Leary’s excellent book on American Patents.  Nevertheless, if you can get one, it is worth reading for the collector interested in American pieces.  Self published, Library of Congress Catalog #93-90553

German Corkscrew Patents 1877 – 1956 –   Wolfgang Handel’s Book is an early effort on collecting German Patent information.  The good thing about this one is that the entire patent documents are included, but in German.  It is out print now and has been superseded by several new books by other German Collectors.

Corkscrews – Fred O’Leary’s Book is THE book on American patent corkscrews.  A wonderful piece of writing backed by excellent research.  It is the complete works!  Ever since it saw the light of day, only a couple of patents have shown up that were missed.  A definite must for any serious corkscrew collector.  Has 500 photographs and a 1,000 U.S.Patents from 1851 to 1994.   Published by Schiffer in 1996, ISBN 0-7643- 0018-0.  Copies are available from the author by e-mail: FOL or from Amazon.com.

Deutscher Gebrauchsmusterschutz fur Korkenzieher – Klaus Pumpenmeier’s Book is in German and is the most extensive book on German patents.   Pumpenmeier is a serious researcher and knows his German corkscrews.  The book is in very limited edition, so it will be hard to get.  Filled with patent information, many colour photos and other good stuff.

Tire Bouchons Français – This 1995, self published book by Guy Olive on French patents is also a must for those who need to know how the French were doing in this business.  An excellent research based quite complete collection of patent information from 1828 to 1974 on French corkscrews.  Out of print now.

The Ultimate Corkscrew Book – Donald A. Bull.  What a contribution to the corkscrew scene! Don Bull had created a book that is remarkable in several dimensions: the pictures are of the highest quality; the descriptions of the pieces are very accurate and the price guide is just a little misguided (I think he pays too much).  Most importantly, the book can be used as a reference to what is out there, almost like a stamp catalogue, a must have for the corkscrew collector.  It is available from Amazon.com which offers a large discount.  You can also order it from the author by e-mail: DB ISBN 0-7643-0701-0

Pocket Guide to Corkscrews – Donald Bull’s second Book is a soft cover “pocket guide” if you have large pockets.   Nicely organised and well put together.  As for his first, big book, this has prices in it also, and similarly, they are well at the high end of the scale. The book is in print and can be bought from any good bookstore as well as from Amazon.com which offers a large discount.  Many will not stock it but will order it for you.  You can also order it from the author by e-mail: DB Similarly published by Schiffer ISBN 0-7643-0793-2

The Corkscrew a Thing of Beauty – Paolo de Sanctis and Maurizio Fantoni.  This is a terrific book presenting the collections of two serious Italian collectors in 373 colour photos showing over 1,000 items.  The book’s main value is the superb pictorial presentation of many usually not seen Italian pieces.  The book is out of print.  Marzorati Editore, Italy, ISBN 88-280-0098-8, 1990. 

La Collectione Tire-Bouchons – Paolo de Sanctis and Maurizio Fantoni.  They created this second book in 1993 as part of a coffee table set for Bompiani, the publisher.  The contents are essentially the same as those of their first effort.  Beautiful colour pictures, not much text but is a picture album of many rare and not-so-rare pieces.  Out of print, but a few copies are available from an Italian source, just e-mail for arrangements: libri.gg@dmw.it

French Corkscrew Patents – Joseph C. Paradi, self published, 1988.   This is the first collection of French corkscrew patents and contain about 100 patents.  A later book by Guy Olive has substantially expanded the list.  The book consists of patent illustrations only taken from the actual patent papers.  The book is available from the author by e-mail order: through this website’s FEEDBACK function (I am the Webmaster).

Korkenzieher – Mannfred Heckmann’s book was one of the very early efforts in writing a book about corkscrews.  He is/was (he sold his collection in 1998 at a Christie’s auction) a corkscrew dealer in Berlin, the book is in German, unfortunately.  Not a well researched book and is useful only as a historical piece in the quest for corkscrew information.  He did add a nice touch by including a small T type corkscrew on a string as a book mark.  Out of print, but some copies are still available from the author.   Fasanen Edition, 1979, Drydens Printers Ltd., London

Het Wijn Leesboek – This is actually a book on wines, written by Hubrech Duijiker.  But Ferd Peters supplied the corkscrews which are pictured all through the book.  The book is in Dutch and was published in 1992.   ISBN 90 714 4246 2.  I doubt that it is still in print, but you may be able to inquire from Ferd by e-mail: FP

Mechanical Corkscrews – Ferd Peters, the best of all books for mechanical corkscrews.  This new book is one of the top books in corkscrew collecting.  Ferd Peters had outdone himself with the help of many of his friends who provided pictures of their great mechanical corkscrews.  This gave the author the opportunity to present a dazzling array of material which could easily meet the most demanding corkscrew collector’s needs – ISBN 90 805058 1 1.  Purchase from the author directly: FP

Just for Openers – Don Bull.  This is also the name of a beer cap opener collectors group.  This one is about cap lifters and beer openers, but has some corkscrews in it as long as they have a beer advertisement on them.  Available from the author DB or a bookstore.

Les Fabriques Français de Tire-Bouchon (French Corkscrew Manufacturers) 1820 – 1970 – Gérard Bidault, March 2000.  Although the book is written in French, the material in it is absolutely fantastic – well worth the time with a dictionary in hand.  This is the definitive book on French corkscrews and for the first time clears up a great deal of the confusion about who made what and which markings represent which manufacturer.  This is a must have book – published by the author and can be ordered only directly from him:   GB
