Update, June 17, 2018: In addition to providing a link to the original blog post, any use of content that I, Miles Spencer Kimball, own should include the notice:

Used by permission according to a temporary nonexclusive license expiring June 30, 2024. All rights reserved.

Additionally, content that I own, but which first appeared in another outlet needs that other outlet acknowledged. In those cases, I provide the modified notice, but the date of expiry should be adjusted to June 30, 2024. For example, "The Coming Transformation of Education: Degrees Won’t Matter Anymore, Skills Will" has listed as the appropriate notice

© February 9, 2015: Miles Kimball, as first published on Quartz. Used by permission according to a temporary nonexclusive license expiring June 30, 2017. All rights reserved. 

Going forward, this can be modified to:

© February 9, 2015: Miles Kimball, as first published on Quartz. Used by permission according to a temporary nonexclusive license expiring June 30, 2024. All rights reserved. 

The purpose of the revocability and expiration clauses is to keep open the possibility of commercial deals in which I give some entity exclusive rights to some of this content (or exclusive rights with some exceptions). The date June 30, 2024 is chosen as a period of time within which I am quite confident there will be no such commercial opportunities. If I become quite confident there will be no such commercial opportunities for a longer period of time, I will post another update here. 

June 25, 2015 Update

I have extended the permission to June 30, 2020. All occurrences of “June 30, 2017,” “June 30, 2015,” “June 30, 2014” and “June 30, 2013” below and in the model copyright notices I sometimes provide within a post should be considered as changed to “June 30, 2020.” For material that appeared first on supplysideliberal.com (the default), use of that material beyond fair use must be accompanied by both a link to the original post and the following notice:  

© [date on the post]: Miles Kimball. Used by permission according to a temporary nonexclusive license expiring June 30, 2020. All rights reserved.

For anything published first on another website, I will specify the required notice in the post that repatriates that publication to supplysideliberal.com. However, the date in that notice should be changed to June 30, 2020.

April 11, 2014, Update

I have extended the permission to June 30, 2017. All occurrences of “June 30, 2015," "June 30, 2014” and “June 30, 2013” below and in the model copyright notices I sometimes provide within a post should be considered as changed to “June 30, 2017.” For material that appeared first on supplysideliberal.com (the default), use of that material beyond fair use must be accompanied by both a link to the original post and the following notice:  

© [date on the post]: Miles Kimball. Used by permission according to a temporary nonexclusive license expiring June 30, 2017. All rights reserved. 

For anything published first on another website, I will specify the required notice in the post that repatriates that publication to supplysideliberal.com. However, the date in that notice should be changed to June 30, 2017. 

October 9, 2013, Update

I have extended the permission to June 30, 2015. All occurrences of “June 30, 2014” and of “June 30, 2013” below should be considered as changed to “June 30, 2015.” For material that appeared first on supplysideliberal.com (the default), use of that material beyond fair use must be accompanied by both a link to the original post and the following notice:  

© [date on the post]: Miles Kimball. Used by permission according to a temporary nonexclusive license expiring June 30, 2015. All rights reserved. 

For anything published first on another website, I will specify the required notice in the post that repatriates that publication to supplysideliberal.com.

March 12, 2013, Update

1. I have extended the permission to June 30, 2014. All occurrences of “June 30, 2013” below should be considered as changed to “June 30, 2014.” For material that appeared first on supplysideliberal.com (the default), use of that material beyond fair use must be accompanied by both a link to the original post and the following notice:  

© [date on the post]: Miles Kimball. Used by permission according to a temporary nonexclusive license expiring June 30, 2014. All rights reserved. 

2. For posts that previously appeared on Quartz, I will put the text of the notice that should be included with use of material from that post, in order to give credit to the original appearance of the material on Quartz. The general form will be:

© [date of first publication on Quartz]: Miles Kimball, as first published on Quartz. Used by permission according to a temporary nonexclusive license expiring June 30, 2014. All rights reserved. 

A link to the original Quartz article must be included.

August 6, 2012 Update (Preamble to the August 5, 2012 Legal Notice) 

For those wanting to refer to this blog, a fair use summary or quote plus a link will always be OK, but if you want to do more, read on.

I have been approached by one website interested in putting up enhanced versions of some of my posts on their site, and another interested in doing a Japanese translation of some of my posts. I want to encourage this kind of thing in the near future, but I want to make sure to be able to sign the standard legal documents in a book deal (or online equivalent) down the road.  

So from now until June 30, 2013, I am allowing reprinting of my posts in full with a clearly visible and clearly identified working link to my blog (or the closest equivalent for paper copies) and the following notice:

Copyright: Miles Spencer Kimball. Used by permission according to a temporary nonexclusive license expiring June 30, 2013. All rights reserved.

The full reprint would have to be taken down on June 30, 2013, and print copies could not be sold or transferred after that date. The details are below, below the row of asterisks.

I found wrestling with the intellectual property law issues involved in crafting this legal notice interesting. I am not a lawyer, but my father, brother and sister are all lawyers (though not specialists in intellectual property law), which makes me more aware of legal issues than I would otherwise be. I crafted this legal notice myself.

August 5, 2012, 11:34 AM Eastern Daylight Time

I, Miles Spencer Kimball, author of the content on supplysideliberal.com, currently appearing as the Tumblr blog http://www.tumblr.com/blog/supplysideliberal, am publishing this legal notice. This legal notice supersedes an earlier legal notice relating to reproduction or use of content on this blog: “Notice of Revocable Permission to Reproduce Content from this Blog with Appropriate Attribution to this Blog and Notice of Miles Spencer Kimball’s Copyright.” Nothing in this notice or earlier notices affects people’s right to make fair use of content from this blog, according to the legal doctrine of “fair use.” 

My legal intent is this: in order to promote this blog and its ideas, I want to give permission for people to reproduce and use content from this blog for a window of time beginning now and ending on June 30, 2013, while retaining all the rights necessary for me to be able to promise exclusive use of content from this blog to a publisher or other party I name in the future. Only I, Miles Spencer Kimball, at my sole discretion, have legal authority to extend the date June 30, 2013 after which reproduction or use of content from this blog (beyond legally established fair use) must cease and desist.

At my sole discretion, I, and only I, also have the legal authority to extend this date for some uses of the content of this blog but not for others. This requires specific authorization from me.  (For example, anyone wishing to translate content from this blog to a language other than English and reproduce or use that translation beyond fair use should contact me.)

Three legal issues have come to my attention:

1. The need to insure that third parties are informed of the limitations I have placed on reproduction or use of content from this blog.  
2. The need to insure that no one relies on being able to reproduce or use content from this blog after June 30, 2013. 
3. The need to insure that (a) no one can limit in any way my right to reproduce and use content from this blog that I have authored and (b) no one can limit in any way my right to permit others as I see fit to reproduce and use content from this blog that I have authored.

Therefore, I require that anyone who reproduces or uses content from this blog (beyond fair use) include in an easily visible way the following notice, word for word as it appears in the block quote immediately below:

Copyright: Miles Spencer Kimball. Used by permission according to a temporary nonexclusive license expiring June 30, 2013. All rights reserved.

IN ADDITION, I require that anyone who reproduces or uses content from this blog provide easily visible and clearly identified working links to this blog or the relevant post or posts on this blog, UNLESS they are technologically unable to do so given the form of reproduction or use. I REQUIRE that anyone technologically unable to provide a working link to this blog or its posts must provide in an easily visible way (a) the web address in the following block quote 

http://blog.supplysideliberal.com 

AND (b) the corresponding web address or addresses of the relevant post or posts.

Unless I, Miles Spencer Kimball, duly authorize otherwise, the following steps (among others) must be taken to cease and desist any use (beyond fair use) of content from this blog after June 30, 2013:

1. At or before midnight, June 30, 2013, all reproductions or uses of content from this blog beyond fair use must be taken down from all websites other than this one.
2. No print reproduction of content from this blog may be sold or transferred in any way from one party to another after June 30, 2013.  
3. No electronic file containing content from this blog may be transferred in any way from one party to another after June 30, 2013. (However, until further notice, people may view supplysideliberal.com itself on any device, and RSS feeds may transfer content from a post within 24 hours of its posting, as long as this content is not thereafter transferred from one party to another more than 24 hours after it is posted.)

LIMITATIONS TO THE TEMPORARY NONEXCLUSIVE LICENSE EXPIRING JUNE 30TH, 2012:

LIMITATION 1: The temporary, nonexclusive license I am hereby giving to reproduce and use content from this blog until June 30th, 2012 does NOT extend to anything I write or otherwise create that appears on any other website. It only applies to content taken directly from this website. That is, you must be able to see the content you want to reproduce or use at a web address that begins with the characters     http://blog.supplysideliberal.com   in order for the permission above to apply.  

LIMITATION 2: The temporary, nonexclusive permission I am hereby giving to reproduce and use content from this blog until June 30th, 2012 does NOT extend to any post appearing on this website (including any content in the comments to that post to which I hold copyright) if the post has a notice of exception at the top of the post (above other content but below the title).  

Two notes:

1. For students, I think it would be especially valuable to send them to this blog itself, because they might click on some economics beyond what is assigned and learn even more!
2. Limitation 1 means that if I take something down from the website, the temporary nonexclusive permission no longer applies even before June 30, 2012, since you have to be able to take it directly from the most recent version of the website.  Also, in the much more common case of a post that has had some revisions, it means that you need to use the most recent, updated version of a post, taken directly from the current version of the website at the time you need to download.
