FREKACE. 
 
 The following L,ist (Part I) and Catalogue (Part II) was compiled in response to 
 demands for information in regard to the publications of the United States Coast and 
 Geodetic Survey, and relates entirely' to these publications: 
 
 Previous to July i, 1878, this Bureau was called the United States Coast Survey, 
 which explains the apparent discrepancy in the title of the publications issued before 
 and since that date. 
 
 The List is arranged in chronological order and the Catalogue alphabetically by 
 authors, subjects, and places, with numerous cross references. All of the subject 
 headings used in this Catalogue are given in systematic order at the beginning of 
 the Catalogue. 
 
 The publications in the List and Catalogue marked " Exhausted" are no longer 
 ayailable for distribution. All others can be obtained, free of charge, upon application 
 to the Superintendent United States Coast and Geodetic Survey, Washington, D. C, 
 except the Coast Pilots and Tide Tables, which are sold at the cost of paper and 
 printing. 
 
 Indexes and catalogues of the Survey's publications have previously been issued 
 under the following titles:

Part L— LIST. 
 
ANNUAL REPORTS. 
 
 The Annual Report of the Superintendent of the United States Coast and Geodetic 
 Survey, fully illustrated with maps and diagrams, is made under law to Congress at 
 each session, and shows in detail the persons employed, the work accomplished, and 
 the expenditures under the annual appropriations. 
 
 Originally appearing as a document in the Congressional series only, it has also 
 been pubHshed in a separate Survey edition since 185 1. For 1851 separate volumes 
 were issued for the text and for the sketches. From 1891 to 1894, inclusive, the 
 report proper and the appendices were printed in separate volumes as Parts I and II. 
 With these exceptions the report has been issued annually since 1851 in one quarto 
 volume. 
 
 The appendices on scientiiic and professional subjects include almost all of the 
 material of that character published by the Survey, whether issued in some other series 
 or not. The appendices have also been printed apart from the reports in "separate" 
 form when the demand for them has warranted such publication. 
 
 In the earlier reports of the Coast vSurvey statements of progress made in office 
 operations will generally be found following the abstracts of reports of field work, 
 attention also being called to office work of special interest or importance in the 
 introductory portions of the reports. This will be found to apply to the annual reports 
 from 1844 to 1855, inclusive. 
 
 In the reports from 1856 to 1864, inclusive, in addition to the notices of office 
 operations in the body of each report, there are appendices which contain reports from 
 the chiefs of the divisions of the office, or, in some cases, the complete reports of the 
 assistant in charge of the of&ce and of the chiefs of divisions. 
 
 The publication of the annual reports of the assistant in charge of the office and 
 of the chiefs of the office divisions was discontinued during the jears 1865 to 1880, 
 inclusive, and the references to office operations were made in the same manner as those 
 in the annual reports of the Survey from 1844 to 1855, inclusive, these' references being 
 supplemented by appendices giving lists of drawings or engravings of charts in progress 
 or completed and by appendices detailing the field and office work relating to tides. 
 
 In the annual report for 1881 the reports made by the chiefs of the computing, 
 tidal, drawing, engraving, and hydrographic divisions of the office were printed in full; 
 in the report for 1882 these reports were published as Appendix No. 6; in the annual 
 reports of the Survey from 1883 to 1889, inclusive, the annual reports of the assistant 
 in charge of office and topography and of the hydrographic inspector appear as 
 Appendices Nos. 4 and 5; in the annual report for 1890 Appendix No. 4 contains the 
 annual report of the assistant in charge of the office, Appendix No. 5 the annual report 
 of the hydrographic inspector. Appendix No. 6 the annual report of the disbursing 
 agent, and Appendix No. 7 the annual report of the assistant in charge of the office of 
 weights and measures. 
 
 It has not been deemed advisable to add to the length of this List by including these 
 oflSce reports, embodying as they do much matter relating to routine operations and 
 details of value chiefly for official reference.

Eeport 1807. COAST AND GEODETIC SURVEY PUBLICATIONS. 
 
 The office of standard weights ana measures was organized under the Superin- 
 tendent of the Coast Survey in 1831, and its reports have been issued regularly since 
 1837 as a part of his official report. They are therefore contained in the following list 
 of reports. 
 
 Many individual scientific papers on standards based on the work of this office were 
 printed as appendices in the report of the Superintendent of the Su^-vey. All of them 
 will be found grouped under the subject headings "Standards" and "Weights and 
 measure office" in the Catalogue (Part II). 
 
 On July I, 1901, the act of Congress approved March 3, 1901, creating the National 
 Bureau of Standards, became fully operative and on that date it became an independent 
 Bureau.

 Footnote to first page. — This article originally appeared in the Coast survey Report for 1855, appendix 48, 
 and was continued in reports of 1856, 1S58, and 1S59, appendix 24, pp. 296-305. In the second edition, in 
 Coast survey Report for 1874, appendix 8, pp. 72-108, the investigation appears greatly extended; the 
 substitution of a sine for a cosine function was made, and the epoch was changed from 1830 to 1850; 
 also some use was made of Cauchy's method of interpolation for the establishment of some second 
 periodic terms. The third edition, issued in June, 1879, appeared in pamphlet form, and is not con- 
 tained in any annual Report of the Coast and geodetic survey. The geographical range of the investi- 
 gation was much enlarged, and the paper was illustrated by two plates. The next or fourth edition 
 was brought out in June, 1881, and forms appendix 9, Coast and geodetic survey Report for 1879; it was 
 illustrated with three plates. In the fifth edition, of^November, 18S2, appendix 12, Report for 1882, there 
 were discussed 837 declinations, obsei-ved at 82 .station.s. situated in the United States and a few in 
 Europe, South America, Asia, and Polynesia, the latter for the purpose of extending our knowledge of 
 magnetic changes beyond our immediate seacoast. The sixth edition forms appendix 12, annual Report 
 for 1886; it is di.-tinguished by a more systematic arrangement of its contents and by a more liberal 
 introduction of observations made at sea near our coasts; besides the number of stations to which the 
 record and discussion extends is increased to 34, with an available material of 1.071 observed declina- 
 tions. In the seventh edition the stations are increased to 102 and the number of declinations to 1,245. 
 The Report for 1895, appendix 1, contains the eighth edition.

BULLETINS. 
 
 Bulletins are issued by the Survey from time to time as material accumulates. 
 They are intended to give early announcement of work accomplished or information 
 of importance obtained, and in many cases anticipate the usual means of publication 
 afforded by the Annual Reports. They are indexed when their number demands it, 
 thus augmenting their value for preservation and reference.

SEPARATELY ISSUED PUBLICATIONS. 
 
 For various reasons papers have been published on a variety of professional, 
 scientific, or historical subjects in separate form and without serial number. They are 
 here listed from the beginning, in the order of their issue. Only a few of these have 
 also been printed in the Annual Reports. They are special publications without a 
 serial number. 
 
 These publications vary greatly in sizes and style of printing, the form being 
 determined largely by the purpose they are intended to serve. Some of them, such as 
 tables, etc., are printed on cardboard for use in the field; and others, such as star 
 catalogues, larger in size, are printed and substantially bound with reference to 
 similar use.

COAST PILOTS. 
 
 Coast Pilots were first begun as a series of publications in 1869. Previously to 
 that coast pilot matters appeared from time to time in appendices to the annual reports. 
 For a list of these appendices, see Coast Pilot in the catalogue. 
 
 The latest editions of the Coast Pilots are on sale at all of the chart agencies of the 
 Survey, located in the principal cities on the coast. The Coast Pilots are now published 
 under the following titles: United States Coast Pilot — Atlantic coast — Parts I-II to 
 VIII, extending from Maine to Texas, inclusive. United States Coast Pilot — Pacific 
 coast — California, Washington, and Oregon. United States Coast Pilot — Alaska — 
 Part I. 
 
 Coast Pilot information relating to Bering Sea and the Arctic Ocean is also con- 
 tained in Bulletin No. 40. Supplements to all the volumes are issued whenever new 
 information makes it necessary, pending the revision of the volumes and the issue of a 
 new edition. All volumes are corrected to date of issue by the Survey.

TIDE TABLKS. 
 
 Like many other publications of the Survey the Tide Tables were first issued as 
 appendices to the reports. They were issued as an independent series in 1866. In that 
 year the Tables were divided and issued separatelj' for the Atlantic and Pacific coasts 
 of the United States. In 1895 the Tables for the two coasts were combined into one 
 volume from which was reprinted an edition for the Pacific coast, and, in 1901, a .similar 
 edition for the Atlantic coast. At present the Tide Tables also contain predictions for 
 the principal foreign ports.
