1. Latitude/longitude, including for days in port, show representative decimal positions for each day, as calculated by the Old Weather project's analysis program. As such, they differ by varying amounts from the positions recorded, usually at noon, in the log pages. In addition, some latitudes/longitudes have been amended in edited logs for errors in the logs, for errors in identifying locations by the analysis program, or simply for greater accuracy. In all cases, refer to the log-page scans for the positions as originally recorded. Not all log pages contain this information and the ships' positions have therefore often been estimated.
2. Full account of any day is available by clicking on the link above that day. Any groups of links may refer to log book covers and introductory information; some may be blank.
3. Logbook events have been formatted but not edited. The quality and quantity of transcribed information therefore varies, and may include up to 3 versions of the same data depending on the number of volunteers working on the originals.
