A neat old book

Jewelry Discussion
#1

Hello all,

I was cleaning out my file cabinet, you know that dreaded chore one
should do every once in a while. I came across a little book my
Professor gave me years ago, it was printed in the 1940’s by Nelson-
Hall Co. Publishers: “Cyclopeia of Valuable Information for Jeweler
Watchmaker Optician”. It originally cost $2.50.

Anyway this little book is full to the brim with all kinds of
that gets lost in time but is so valuable to those of us
that work with things OLD and new. It has formulas for metals,
cements, patinas, colourations and cleaning

I am Not selling my copy BUT:

I looked for it in the internet to see if it was still being
publisher but found only two old copies on Alibris.com, both are in
the UK. It is the kind of thing that should be shared with others
that work in the industry.

Has anyone else ever seen this book and the amazing bits of
it holds?

Just an FYI,
Cynthia Thomas

Is this book still under copyright or is it old enough to have
fallen into public domain? Check the original copyright date. It
would be a pity of have valuable lost when we can
preserve it.

We cannot find any copyright marking/date in the booklet. Actually
the is a compilation of derived from many
sources so I don’t know if it COULD be copyrighted. We are looking
into it and if it is not, we may put it up on our website . We will
let you know.

This book would need to be researched. You can start at
http://www.copyright.cornell.edu/training/Hirtle_Public_Domain.htm.

It is not in the Copyright Office database but its copyright
renewal, if there was one, (under “Cyclopeia” or “Cyclopedia”)
probably predates the computerized records so its omission there is
not an answer. See footnote 7 of the link for further research.

Hi Starstones,

Not yet. It has to have been published before 1923. from Wikipedia:

  The Sonny Bono Copyright Term Extension Act of 1998 extended
  copyright terms in the United States by 20 years. Before the
  act, an author's copyright would last until fifty years after
  his death. After the act, an author's copyright would last
  until seventy years after his death, while copyrights for
  works of corporate authorship would last 75 to 95 years. The
  act also affected copyright terms for copyrighted works
  published prior to January 1, 1978, increasing their term of
  protection by 20 years as well. This effectively 'froze' the
  advancement date of the public domain in the United States for
  works covered by the older fixed term copyright rules. Under
  this act, no additional works made in 1923 or after, that were
  still copyrighted in 1998, will enter the public domain until
  2019. Unlike copyright extension legislation in the European
  Union, the Sonny Bono Act did not revive copyrights that had
  already expired. However, the act did extend terms already set
  by previous acts, and is retroactive in that sense....

I have an obviously newer copy, the price was $6.95 when it was
printed. A watchmaker friend of mine gave it to me years ago. The
cover says it is “privately printed for the trade-not sold outside
the trade” and was printed by Golden Times Enterprises 7120 Liberty
Lane, Vacaville, CA 95688.
