We have been publishing the Report and the Technical Note of the Port and Harbour Research Institute (P.H.R.I.), as fruitful results of our research, since the establishment of our institute, April 1962. The former mainly consists of highly completed studies and is numbered in the order of publication in every calender year. The latter consists of useful technical papers and is numbered consecutively. Since we have already published as many as 520 papers in the Report and 568 papers in the Technical Note, most people are experiecing diffculty in searching the papers which they would like to read. With regard to the Technical Note, the publication List was already published in December 1984 as the Technical Note No.500. This Note arranged all the Technical Notes from No.1 to No.499.
　The report of P.H.R.I was first published in 1963 and the Report, Vol. 25 No 4, will be published in December 1986. The Reports, Vol.1 to 6, had been issued unperiodically and separated into Japanese and English editions. Since Vol. 7, the Report has been quarterly inprinted and has contained both papers in Japanese and English.
　Under these circumsbtances, the Editorial Board, authorizing and governing all of the publications of P.H.R.I., has decided to issue the Publiction List of the Report of P.H.R.I.. This List is composed of two parts. One is the classified list in which all the original papers in the Reports are categorized into each research field. Another is the title list in which titles of the papers are arranged through in the orer of publication. For the classified list, we have used our own P.H.R.I. classification method similar to the Japan Decimal classification Method. The classified list is given in Japanese only, but the title list consits of both the Japanese and the English editions.
　We hope this Publication List would further facilitate the readers of the Report of the port and Research Institute
