BCRA Online Archive - BSA Records

We are delighted to report that after many years, indeed decades, the first tranche of the BSA Records is now online in the BCRA Online Archive. For this we must thank Alan Jeffreys and John Manchip from the Grampian Speleological Group who undertook the task of photographing and processing the material in Edinburgh, using equipment supplied by the British Geological Survey. This was a hugely time-consuming task, and we are deeply indebted to them for their efforts.

For younger readers, the British Speleological Association (BSA) was founded as a national organisation in 1935 by Eli Simpson, who remained its driving force until his death in 1962. Whilst encouraging the exploration of caves, the BSA considered itself to be a scientific organisation, and set great emphasis on recording everything speleological. Simpson was the Hon. Recorder until his death, and he accumulated a vast quantity of information, much of which was stored in a set of large folders some one hundred strong. The role of Hon. Recorder continued after his death, but relatively little was added. The records contain accounts of many important explorations from all round the country, such as the Mossdale explorations, and a large number of photographs.

About half of the collection's 196 documents have been uploaded - a total of 26,556 images. It is hoped that the remaining documents will become available later this year. In time, it is intended that an index will be available for each of the documents - currently, only the photograph albums and prints from their negatives have indexes. The collection has a browser on the front page which will hopefully help users to find the material they are interested in.

This is one of the most important collections in UK caving, and we are so pleased that it is at long last being made available to the caving community.

The collection may be visited at: https://archives.bcra.org.uk/bsa.html.
 
With both Google Chrome and Firefox 129, If I left click on one of the links, I see the new page. However if I middle click or right click and select "open link in new tab", it takes me to "https://archives.bcra.org.uk/archive.php?" instead. The odd thing is that once I've gone to a link, right click starts working!

Thank you for your feedback. This is probably the result of the large amount of coding effort that has been put in to ensure that the site cannot be image-scraped. The Online Archive currently holds over 33,000 images with an average size of 2 Mb, almost all of which are held on the Cloud. The bandwidth costs of allowing AI image-scraping bots to download that much data several times of day would be more than we could afford. You may be interested to view the generated HTML source code for any page below the home page to gain an insight into some of the techniques being used.

The default result for any request that is deemed by the software to be unfriendly or invalid is to return it to the home page, with an appropriate HTTP return code, which is what you are encountering.

I suspect that I haven't specifically catered for right-click actions. I will investigate the issue, and report back.

I have investigated the problem.

For search engine purposes, the links are in the standard format at the top level of the archive - e.g.
'<a href="?level=collection&collection=bsa">. '

Right click will work as normal.

At lower levels, the links are in the format:
'<a href="?" data-href-modifier="Fetch:cGlFo!sND!dZI!YV!!P!ovaaf!Q!acp!V!0">'
and are transformed when the link is selected.

When you right click on this link and select from the context menu "Open link in new tab", the transformation isn't actioned, and so you are taken to the top level as specified by the '<a href="?"' part of the statement.

I don't want to disable the right-click context menu, as that also allows one to download an image, but I may be able to work out some sort of compromise solution.
 
I think, if you were to add, after the href="?"
Code:
target="_blank"
Then all links would open in a new tab, which is probably what people would prefer, and so avoids the need to right-click on them.

Thank you for the suggestion. I am not currently convinced that people would, as a matter of course, prefer a new tab when they selected a link. They would finish up with five open tabs just get to a larger version of the first image, and could easily generate tens of static tabs just by browsing. I would personally find this over the top when accessing the online archive on a desk-top browser, and it would also be expensive on browser memory and performance. Having said that, I am happy to be persuaded by better counter arguments.

I do understand that opening a link in a new tab is useful when one is wanting to have one or more active browsing threads, which is why I have expressed my intention to look for a compromise solution.

I have looked at the possibility of intercepting the right-hand mouse click, but the display of the context menu takes precedence over anything I want to do, and I want to retain that context menu as it has other useful functions.

All is not lost, however, as one can open a link in a new tab by clicking Ctrl/left-click or Ctrl/Enter in the three most commonly used browsers. I think that's a small price to pay to keep out the image scrapers.
