Background and Lesson Goals
Now that you have learned how Wget can be used to mirror or downloadspecific files from websites like ActiveHistory.ca via the commandline, it’s time to expand your web-scraping skills through a few morelessons that focus on other uses for Wget’s recursive retrievalfunction. The following tutorial provides three examples of how Wget canbe used to download large collections of documents from archivalwebsites with assistance from the Python programing language. It willteach you how to parse and generate a list of URLs using a simple Pythonscript, and will also introduce you to a few of Wget’s other usefulfeatures. Similar functions to the ones demonstrated in this lesson canbe achieved using curl, an open-source software capable ofperforming automated downloads from the command line. For this lesson,however, we will focus on Wget and building your Python skills.
Archival websites offer a wealth of resources to historians, butincreased accessibility does not always translate into increasedutility. In other words, while online collections often allow historiansto access hitherto unavailable or cost-prohibitive materials, they canalso be limited by the manner in which content is presented andorganized. Take for example the Indian Affairs Annual Reportsdatabase hosted on the Library and Archives Canada [LAC] website. Sayyou wanted to download an entire report, or reports for several decades.The current system allows a user the option to read a plaintext versionof each page, or click on the “View a scanned page of originalReport” link, which will take the user to a page with LAC’s embeddedimage viewer. This allows you to see the original document, but it isalso cumbersome because it requires you to scroll through eachindividual page. Moreover, if you want the document for offline viewing,the only option is to right click –> save as each image to adirectory on your computer. If you want several decades’ worth of annualreports, you can see the limits to the current means of presentationpretty easily. This lesson will allow you to overcome such an obstacle.
Recursive Retrieval and Sequential URLs: The Library and Archives Canada Example
Let’s get started. The first step involves building a script to generatesequential URLs using Python’s ForLoop function. First, you’ll need toidentify the beginning URL in the series of documents that you want todownload. Because of its smaller size we’re going to use the online wardiary for No. 14 Canadian General Hospital as our example. Theentire war diary is 80 pages long. The URL for page 1 ishttp://data2.archives.ca/e/e061/e001518029.jpg and the URL for page80 is ‘http://data2.archives.ca/e/e061/e001518109.jpg. Note thatthey are in sequential order. We want to download the .jpeg images forall of the pages in the diary. To do this, we need to design a scriptto generate all of the URLs for the pages in between (and including) thefirst and last page of the diary.
Open your preferred text editor (such as Komodo Edit) and enter the codebelow. Where it says ‘integer 1′ type in ‘8029′, where it says ‘integer2′, type ‘8110’. The ForLoop will generate a list of numbers between‘8029’ and ‘8110’, but it will not print the last number in the range(i.e. 8110). To download all 80 pages in the diary you must add one tothe top-value of the range because it is at this integer where theForLoop is told to stop. This applies for any sequence of numbers yougenerate with this function. Additionally, the script will not properlyexecute if leading zeros are included in the range of integers, soyou must exclude them by leaving them in the string (the URL). In thisexample I have parsed the URL so that only the last four digits of thestring are being manipulated by the ForLoop.
Now replace ‘integer1′ and ‘integer2′ with the bottom and top ranges ofURLs you want to download. The final product should look like this:
Save the program as a .py file, and then click run the Python script.
The ForLoop will automatically generate a sequential list of URLsbetween the range of two integers that you specified in the brackets,and will write them to a .txt file that will be saved in yourProgramming Historian directory. The
%d
appends each sequential numbergenerated by the ForLoop to the exact position you place it in thestring. Adding n
to the end of the string removes line-breaks,allowing Wget to read the .txt file.You do not need to use all of the digits in the URL to specify the range– just the ones between the beginning and end of the sequence you areinterested in. This is why only the last 4 digits of the string wereselected and
00151
was left intact.Before moving on to the next stage of the downloading process, make sureyou have created a directory where you would like to save your files,and, for ease of use, locate it in the main directory where you keepyour documents. For both Mac and Windows users this will normally be the‘Documents’ folder. For this example, we’ll call our folder ‘LAC’. Youshould move the urls.txt file your Python script created in to thisdirectory. To save time on future downloads, it is advisable to simplyrun the program from the directory you plan to download to. This can beachieved by saving the URL-Generator.py file to your ‘LAC’ folder.
For Mac users, under your applications list, select Utilities ->Terminal. For Windows Users, you will need to open your system’sCommand Line utility.
Once you have a shell open, you need to ‘call’ the directory you want tosave your downloaded .jpeg files to. Type:
and hit enter. Then type:
and press enter again. You now have the directory selected and are readyto begin downloading.
Based on what you have learned from Ian Milligan’s Wgetlesson, enter the following intothe command line (note you can choose whatever you like for your ‘limit rate’,but be a responsible internet citizen and keep it under 200kb/s!):
(Note: including ‘-nd’ in the command line will keep Wget fromautomatically mirroring the website’s directories, making your fileseasier to access and organize).
Within a few moments you should have all 80 pages of the war diarydownloaded to this directory. You can copy and move them into a newfolder as you please.
A Second Example: The National Archives of Australia
After this lesson was originally published, the National Archvies of Australia changed their URL patterns and broke the links provided here. We are preserving the original text for reference, however you may wish to skip to the next section.
Let’s try one more example using this method of recursive retrieval.This lesson can be broadly applied to numerous archives, not justCanadian ones!
Say you wanted to download a manuscript from the National Archives ofAustralia, which has a much more aesthetically pleasing online viewerthan LAC, but is still limited by only being able to scroll through oneimage at a time. We’ll use William Bligh’s “Notebook and List ofMutineers, 1789” which provides an account of the mutiny aboard the HMSBounty. On the viewer page you’ll note that there are 131 ‘items’(pages) to the notebook. This is somewhat misleading. Click on the firstthumbnail in the top right to view the whole page. Now, right-click ->view image. The URL should be‘http://nla.gov.au/nla.ms-ms5393-1-s1-v.jpg’. If you browse throughthe thumbnails, the last one is ‘Part 127’, which is located at‘http://nla.gov.au/nla.ms-ms5393-1-s127-v.jpg’. The discrepancybetween the range of URLs and the total number of files means that youmay miss a page or two in the automated download – in this case thereare a few URLs that include a letter in the name of the .jpeg(‘s126a.v.jpg’ or ‘s126b.v.jpg’ for example). This is going to happenfrom time to time when downloading from archives, so do not be surprisedif you miss a page or two during an automated download.
Note that a potential workaroundcould include using regular expressions to make more complicated queries if appropriate(for more, see the Understanding Regular Expressionslesson).

Let’s run the script and Wget command once more:
And:
You now have a (mostly) full copy of William Bligh’s notebook. Themissing pages can be downloaded manually using right-click -> saveimage as.
Recursive Retrieval and Wget’s ‘Accept’ (-A) Function
Sometimes automated downloading requires working around coding barriers.It is common to encounter URLs that contain multiple sets of leadingzeros, or URLs which may be too complex for someone with a limitedbackground in coding to design a Python script for. https://graphrenew143.weebly.com/sony-sound-forge-audio-studio-10-download-mac.html. Thankfully, Wget hasa built-in function called ‘Accept’ (expressed as ‘-A’) that allows youto define what type of files you would like to download from a specificwebpage or an open directory.
For this example we will use one of the many great collections availablethrough the Library of Congress website: The Thomas Jefferson Papers. Aswith LAC, the viewer for these files is outdated and requires you tonavigate page by page. We’re going to download a selection from Series1: General Correspondence. 1651-1827. Open the link and then click onthe image (the .jpeg viewer looks awful familiar doesn’t it?) The URLfor the image also follows a similar pattern to the war diary from LACthat we downloaded earlier in the lesson, but the leading zeroscomplicate matters and do not permit us to easily generate URLs with thefirst script we used. Here’s a workaround. Click on thislink:
The page you just opened is a sub-directory of the website that liststhe .jpeg files for a selection of the Jefferson Papers. This means thatwe can use Wget’s ‘–A’ function to download all of the .jpeg images (100of them) listed on that page. But say you want to go further anddownload the whole range of files for this set of dates in Series 1 –that’s 1487 images. For a task like this where there are relatively fewURLs you do not actually need to write a script (although you couldusing my final example, which discusses the problem of leading zeros).Instead, simply manipulate the URLs in a .txt file as follows: Download pages for mac.
… all the way up to
This is the last sub-directory on the Library of Congress site forthese dates in Series 1. This last URL contains images 1400-1487.
Your completed .txt file should have 15 URLs total. Before going anyfurther, save the file as ‘Jefferson.txt’ in the directory you plan tostore your downloaded files in.
https://graphrenew143.weebly.com/blog/8-ball-pool-for-mac-free-download. Now, run the following Wget command:
Voila, after a bit of waiting, you will have 1487 pages of presidentialpapers right at your fingertips! https://graphrenew143.weebly.com/handbrake-download-for-mac-1095.html.
More Complicated Recursive Retrieval: A Python Script for Leading Zeros
The Library of Congress, like many online repositories, organizes theircollections using a numbering system that incorporates leading zeroswithin each URL. If the directory is open, Wget’s –A function is a greatway to get around this without having to do any coding. But what if thedirectory is closed and you can only access one image at a time? Thisfinal example will illustrate how to use a Python script to incorporateleading into a list of URLs. For this example we will be using theHistorical Medical Poster Collection, available from the HarveyCushing/Jack Hay Whitney Medical Library (Yale University).
First, we’ll need to identify the URL of the first and last files wewant to download. We also want the high-resolution versions of eachposter. To locate the URL for the high res image click on the firstthumbnail (top left) then look below the poster for the link that says‘Click HERE for Full Image’. If you follow the link, a high-resolutionimage with a complex URL will appear. As was the case in the AustralianArchives example, to get the simplified URL you must right-click ->view image using your web-browser. The URL for the first poster shouldbe:
Follow the same steps for the last poster in the gallery – the URLshould be:
http://cushing.med.yale.edu/images/mdposter/full/poster0637.jpg.
The script we used to download from LAC will not work because the rangefunction cannot comprehend leading zeros. The script below provides aneffective workaround that runs three different ForLoops and exports theURLs to a .txt file in much the same way as our original script. Thisapproach would also work with the Jefferson Papers, but I chose to usethe –A function to demonstrate its utility and effectiveness as a lesscomplicated alternative.
Download Website Mac Wget Refer Original Url Link
In this script the poster URL is treated in much the same way as the URLin our LAC example. The key difference is that the leading zeros areincluded as part of the string. For each loop, the number of zeros inthe string decreases as the digits increase from single, to double, totriple. The script can be expanded or shortened as needed. In this casewe needed to repeat the process three times because we were moving fromthree leading zeros to one leading zero. To ensure that the scriptiterates properly, a ‘+’ should be added to each ForLoop as in theexample below.
We do not recommend actually performing this download because of thesize and extent of the files. This example is merely intended toillustrate the how to build and execute the Python script.
Conclusion
These three examples only scratch the surface of Wget’s potential.Digital archives organize, store, and present their content in a varietyof ways, some of which are more accessible than others. Indeed, manydigital repositories store files using URLs that must be manipulated inseveral different ways to utilize a program like Wget. Wherever yourdownloading may take you, new challenges and opportunities await. Thistutorial has provided you with the core skills for further work in thedigital archive and, hopefully, will lead you to undertake your ownexperiments in an effort to add new tools to the digital historian’stoolkit. As new methods for scraping online repositories becomeavailable, we will continue to update this lesson with additionalexamples of Wget’s power and potential.
Before
After trick
I am often logged in to my servers via SSH, and I need to download a file like a WordPress plugin. I've noticed many sites now employ a means of blocking robots like wget from accessing their files. Most of the time they use .htaccess to do this. So a permanent workaround has wget mimick a normal browser.
