This book isn't intended for the astronomical data-miner or the
budding astrophysicist so if you buy it expecting to find a
detailed analysis of data management techniques or the latest
theories on double star formation you will be greatly disappointed.
But if you are an amateur astronomer interested in observing double
stars this book will fill your heart with joy. If you are tired of
seeing the same old lists of double stars with the same, decades
old, descriptions then you will love this book because none of
these 1800+ double stars have ever been catalogued before The first
few pages contain an introduction the catalogue - the why and the
how behind its creation. The heart of the book is a detailed list
of these new targets organised by constellation and then by right
ascension within the constellation. Detailed information on
coordinates, magnitudes, separation, position angle and colour is
given for every pair. This book represents a major step forward in
popularising double star astronomy.
I have been a stamp collector for over 40 years, a postal historian
and a philatelist for about 15 of those years and a specialist
collector of revenue stamps and documents for the last 5 years.
I've been a member of some the most friendly and well-run groups
you could ever imagine - the State Revenue Society and the American
Philatelic Society are both examples of best practice - and I even
flirted briefly with philatelic exhibiting. Despite having served
such a lengthy apprenticeship I still don't have an answer to a
really basic question: "Why are postage stamps catalogued,
collected and researched with so much more energy and enthusiasm
than revenue stamps?" There are many countries where there doesn't
seems to be a reliable and up-to-date catalogue of revenue stamps -
certainly not one accessible to a virtual monoglot such as myself.
I think it comes down to what I call "critical mass." Without
enough revenue stamp collectors it is hard for dealers to establish
a viable business but without dealers generating catalogues and
generally raising the profile of this branch of the hobby I suspect
that prospective revenue stamp collectors tend to wander off into
the sunset searching for easier pickings. The Revenue Society has
defined revenue stamps as " ...stamps, whether impressed, adhesive
or otherwise, issued by or on behalf of International, National or
Local Governments, their Licensees or Agents, and indicate that a
tax, duty or fee has been paid or prepaid or that permission has
been granted." This small study is intended to bring to the
attention of the collecting public the sheer diversity of revenue
stamps.
