Just one suggestion mate..! It would have been better if you could include the date and the name of the author of the blog-posts in the corresponding topics of the pdfs.
It would help us to get in touch with the corresponding author directly to clarify any doubts,if any
Please see if this can be done now otherwise
well your note is correct.
The date until the articles was gathered is the the date of post and from this only irrelevant article was did.
The author generally is karishma, articles by Brian Galvin or other are a very minor part of the whole.
You can use their feed and add the article that for you is important to the database. Because add an aticle each time and then repost the same here is a bit cumbersome, if you do not have a "critical mass". In other words, if you have another 50 article is ok , otherwise no. you know what I mean.
In the meantime I add the date-collection
KUDOS is the good manner to help the entire community.
