Sometimes it can be useful to look at pages before or after the page you are working on. If you have an unreadable weather code, you can look at the corresponding events page to see if that gives any hints about the weather (but never try to 'correct' what the log keeper wrote!). If you can't read a place name you can look at earlier and later pages to find another example of the name or information that will give you the general location of the place so that you can look on a map.



The first thing to do is to determine the URL of the image of the log page. This is NOT the same as the address at the top of the page you are transcribing. Follow the instructions under To link to a page in the logbooks: in Caro's post: Posting Links and Images (A Guide).

For this example, we will start with a weather page from Concord's log:
http://oldweather.s3.amazonaws.com/ow3/final/USS%20Concord/vol012of040/vol012of040_094_0.jpg

Paste this address into a new tab (or, in this case, simply click on the link). Note that clicking on the links below with numbers in red will not work correctly because of the embedded codes, but you can copy and paste them.

To look at the corresponding events page, simply change the last digit from a 0 to a 1:
http://oldweather.s3.amazonaws.com/ow3/final/USS%20Concord/vol012of040/vol012of040_094_1.jpg

To look at the previous day's weather page:
http://oldweather.s3.amazonaws.com/ow3/final/USS%20Concord/vol012of040/vol012of040_093_0.jpg

To look at the following day's events page:
http://oldweather.s3.amazonaws.com/ow3/final/USS%20Concord/vol012of040/vol012of040_095_1.jpg

Page numbering does have some quirks, but the methods above are fairly reliable - until you reach the beginning (http://oldweather.s3.amazonaws.com/ow3/final/USS%20Concord/vol012of040/vol012of040_001_0.jpg) or the end (http://oldweather.s3.amazonaws.com/ow3/final/USS%20Concord/vol012of040/vol012of040_201_1.jpg) of the log book!

Beyond this it varies greatly from ship to ship. You will have to experiment.
In this case, "vol012of040" is an obvious starting point. Note that there are two occurrences to change. Also, remember that it is possible that not all volumes are online.
You can see that volume 11 begins in February 1891:
http://oldweather.s3.amazonaws.com/ow3/final/USS%20Concord/vol011of040/vol011of040_007_1.jpg

Experiment and have fun!

Randi,

   This is very helpful, thank you. Something else that I find REALLY helpful is to copy the image (click on the image with the Right Button on the mouse and select Copy Image) and paste it into a viewer (Right mouse button Paste). I use Irfanview, which is brilliant. I convert the image to Greyscale (Alt-I G), then I sharpen it a couple of times (S S), do a colour balance (U), and then enlarge it nine or ten times (++++++++++). The result is a very clean sharp image that is much easier to read. I have been using the keys strokes rather than clicking my way through the menus so often that I don't even have to think about them any more. Reading the logs in Irfanview is so much easier than trying to do it through the Old Weather interface, and it is very helpful on the weather pages, too. I am in the habit of doing this with every page I process.

   Should you want to download Irfanview (I have been using it for years);
