Well done Julian: I just tried it and it works pretty well.

A couple of comments:
  • I got a listing for Bush heritage included in my selection (searching for "whistling duck") see below.  Que?;
  • Could/Should the search be restricted to exclude the Annual Bird Reports?  For more regularly reported species that will add about 40 
    unwanted entries to the list.

It is now possible to search the entire CBN archive via a search box found at the top of the CBN website page – go to > Publications > Canberra Bird Notes.


This is a beta version, meaning it is still being perfected.  To use it, enter your search term in the box and click the magnifying glass.  You will get a page of results, sometimes many results.  They don’t appear in any order so be guided by the date and/or the issue number (at the end of the green link). 


When you click one of the results you’ll download that whole issue of CBN.  Your search term is NOT highlighted in the resulting document so you need to search again within the document  – Control-f in windows to ‘find’ and insert the same search term.


It seems to work well but is completely reliant on the cleverness of your search words to avoid getting thousands of results or none at all.  Sometimes using apostrophes “like this” around your words helps by restricting to that exact phrase, but be aware that then it will not find plurals or other parts of speech.  You’d need to search for “Fuscous honeyeater” and again for “fuscous honeyeaters” to get them all.  On the other hand if you search for Fuscous honeyeater without quotes, it will find honeyeater or honeyeaters but may return items that just contain one of the words.  A technique to find ‘serious’ mentions of a particular bird is to use the scientific name – this generally works well without false alarms.


The older editions of CBN were scanned from paper copies and used OCR (optical character recognition) to read the text.  Errors in the OCR process (commonly where words are concatenated or misspelled) mean that sometimes you may miss an occurrence of something you are looking for.  Unfortunately this will be permanent limitation, though it seems to be quite rare.


You may be asked to prove you’re not a robot at various times, be prepared to do what it asks and then “submit”.


As mentioned this is a work in progress and not all issues of CBN have yet been indexed by google – at the time of writing 108 of 188 have been indexed. 


I would appreciate comments on any problems encountered, or any suggestions.


This has been a long time coming – hopefully it will prove to be useful.
