Mathematics Is Fun: Interesting collections of papers from MAA

One of the reader had notified me that the page:
had lots of "404", or page not found errors.

The blog page was created in 2011, and I guessed by now the website have gone through (referring to MAA) an overhaul.

Indeed, just take the first item in the old blog:

"[PDF] 

A New Minimization Proof for the Brachistochrone"



And immediately from the first returned link:

[PDF]A New Minimization Proof for the Brachistochrone
by G Lawlor - ‎1996 - ‎Cited by 18 - ‎Related articles
A New Minimization Proof for the Brachistochrone. Gary Lawlor. The American Mathematical Monthly, March 1996

You can see that the link URL has changed.   So if there is any old paper in the old blog that is needed, just enter Google and search again.

Otherwise, since now you now it has been migrated to a entire new directory:  

http://www.maa.org/sites/default/files/pdf/pubs/Calc_Articles/ma060.pdf

Therefore, just use Google to start searching from that directory:

https://www.google.com.sg/search?q=site:www.maa.org/sites/default/files/pdf/pubs+filetype:pdf

This is 1560+ documents (only a snapshot here, and sorry for the HTML formatting error below.   Notice too that only the first link is a valid link, the 2nd link in the each search result's URL is not properly copied over, and I am LAZY):
