 The Manual is discussing both theory and different practical problems of map projections together with their development and application to the map design. The authors have made a brilliant attempt to provide readers with the results of years of professional research and experience of many specialists in this fields in a brief and systematical manner. Subject experience relates to any individual working on preparation of the maps; in fact, this is a very first international textbook on the subject using the experience of American and Russian specialists.
The volume may serve as a remarkably precise handbook or practical manual to be used by engineers, scientists and cartographers o solve the practical problems using the methods of mathematical cartography and space imagery. It may also be used for training purposes in the colleges or even for the self-study. The effective solution of the problems relating to the science and commerce is based on a broad use of the maps prepared in various scales, having various contents and released for various purposes.
The publication provides information on the general theory, projections with straight parallels and with parallels in concentric/non-concentric circles, relevant researches, established numerical methods, identification and choice of the projections and many other useful and practical information.
 A world famous set of mathematical tables which was initially published more than a century ago and has been a real bestseller ever since the time of first release. In fact, these tables still remain a fundamental requirement for any person learning the astro-navigation and practicing it, despite all developments if the field of electronic navigation.
Captain Blance, who is the author of the title, has spent a lot of time working on modernization of the tables for the present edition. Some completely new tables have been added while obsolete tables have been deleted in order to fully conform with constantly changing navigation techniques and aiming to improve the accuracy of the calculated position of the vessel plus to reduce the tedium of the these calculations. The volume includes all tables necessary for both deep sea and coastal navigation. The author has applied a simple uniform interpolation method for all tables with trigonometric data.
Note that the volume also includes several tables that are commonly not readily available on the navigation bridge of vessels or ones usually used only in the exam rooms. The author has also completely restructured and significantly updated the section of the book dedicated to the sea ports. All of the ports have been listed geographically in the special order. The index of all addressed sea ports in there at the back of the section.

 The present collection of selected meteorological tables is one of the rarest and oldest navigation publications available. The book was originally published more that hundred and fifty years ago, in 1852. Of course there have been so many technological developments in the field of maritime navigation since then; however, the book will still be good to the people with the interest in practical meteorology.
The main content of the publication has been arranged in four major section. The first section contains thermometrical tables and comparison of the thermometrical scales, in total there are fifteen tables with supplementary information. The second section contains five hygrometrical tables including elastic forces of aqueous vapors, psychometrical tables for deducing the force of vapor, relative humidity etc.
The third section provides barometrical tables including reduction of the barometrical observations. Finally, the last fourth section of the volume contains hypsometrical tables. Each of the series features distinct paging that runs throughout the set, it is there at the page bottom. Have a look in the book and you may like to have it in your collection. The appendix is dealing with the comparison of the English-French length measures.
 This classic publication belongs to the famous and historical The Rudder ON series. The nautical books and other instruments that are commonly used on board marine ships for navigation are usually quite large sized. This does not present any sort of problem on large conventional vessels since there is lot of space available to keep and use them.
However, on smaller ships the crew members usually prefer more compact volumes. That is the reason why the decision was made by the author of this publication to reduce its size to the maximum practical extent. In the meantime every effort was made to include all important information. The volume opens with a chapter devoted to the altitude diagrams also explaining dip of the horizon and parallax.
There are numerous tables included in this section addressing main refraction, difference of latitude and departure for degrees from 1 to 45, log. sines, tangents, and secants, dip of the sea horizon, the Sun's parallax in altitude, correction of the Moon's altitude, and comparison of Admiralty knots and statute miles. The remaining portion of the publication is dealing with using sextant, etc. In short, the book will be interesting for the people who like navigation and are interested with the traditional navigation techniques.
 One of the oldest publications available today and covering the subject of the ocean meteorology. It is a truly classic volume. The main content of the textbook is based on the annual lectures read by the author of this publication at the world famous Royal Naval College. The author has omitted most of the theoretical part making the focuses on the practical issue of making passages from one port to another.
There are eight chapters in this book. The first chapter provides general introductory information about the meteorology, characteristics of the atmosphere, wind force, moisture, rain and clouds, low and high pressure areas etc. The second chapter addresses the ocean characteristics, currents, southern and northern ice etc, while the third chapter has been devoted to the North and South Atlantic Ocean together with the current systems and winds.
The fourth chapter is dealing with the Indian Ocean and passages across it. The last three chapters of the textbook cover the Indian Archipelago and China Sea North Pacific Ocean, again with the wind and current systems, hurricanes and cyclones, prognostics, law of storms, ocean depth and temperature, ocean density and saltiness, circulation of the ocean waters, isothermal charts and many other important aspects of the ocean meteorology.
 The present publication was released to supplement The Nautical Almanac 2018. The content of the document was developed by the TNA Office of the U.S. Naval Observatory working jointly with the UKHO specialists. It will provide navigators with additional information required for safe navigation. The material is arranged thirteen chapters.
The first chapter is covering such phenomena as eclipses, Moon phases and seasons, helio- and geocentric planetary phenomena, perigee and occultations, together with the apogee of the Moon etc. In this chapter the authors are also dealing with the visibility of the Planets, configuration diaries an other relevant matters.
The other chapters of the document address the international time zones and eclipses, moonset and moonrise tables, mean sidereal time and circumpolar stars. They also provide explanation of setting and rising tables, Gregorian calendar, perihelion passages of the comets, magnitudes and elongations of the Planets and other information. As it was a case with the Nautical Almanac, this publication will be useful to the people when it is used as a supplementary tool for their training or daily working activities.
 One of the oldest titles presented here - just imagine, the original release of the publication dates back to 1869. Written by one of the most well known and recognized experts of the past times, this publication was greatly appreciated and well met by the marine navigators. Of course, nowadays, in the century of electronic navigation means the content of this classic volume may seem irrelevant and obsolete.
However, it would be good for any professional navigator of today to have an understanding of the fundamentals of theoretical navigation including the methods that were in use at the very beginning. As it comes from the original title of the book, it contains the azimuth and hour angles for the declination and latitude, and this information used to be necessary to provide safe navigation.
The tables contained in the pages of this volume were used to find azimuth at sea using the hour angle, in all latitudes considered navigable, and an every two declination degrees between the zodiac limits, whenever the sun, planet, moon or known star was observed at any convenient distance from zenith. Have a look in this book to have a general idea what the mariners of the past had to go through when making their sea voyages...
