//For questions, email Stephen X. Flynn, College of Wooster: sflynn (at) wooster.edu

//Updates:
//May 2013 - fixed pubpdf() to detect both "failed" and "notfound" ISSN numbers, similar to finaldraft()
//March 2013 - new functions for Final Drafts and OA mandates

//Instructions: 
//Watch a quick installation video at http://youtu.be/ZMyKVHM5nOc
//(A) Register for an API key at http://www.sherpa.ac.uk/romeo/apiregistry.php then insert the key below in the "Sherpa API key" section of the code. Without an API key, you will be limited to 500 requests per day, per IP address.

//(1) Perform an affiliation search in a large bibliographic database, such as Scopus or Web of Knowledge. Include the ISSN metadata in the database export, since the function depends on the ISSN to work. Export this search to a .csv file.
//(2) Import the .csv into a Google Spreadsheet with at a minimum, columns for the following: ISSN, pubpdf, finaldraft, embargo, checkOAMandate. Other details like Journal title, Article title, and Author are optional.
//(3) CRITICAL: Select the ISSN column, select Format -> Number -> Plain Text. Or else the script won't work!
//(4) Go to Script -> Script Editor
//(5) Copy and paste all the following into script editor window, and save.
//(6) Use the three functions described below in their corresponding columns. For example, =pubpdf(19352735) will lookup the ISSN 1935-2735 (PLoS Neglected Tropical Diseases) in Sherpa/Romeo, and result in the text "Publisher's version/PDF may be used".

//TIP: Go to Format -> Conditional formatting... to set up color codes to help visualize your column outputs.
//TIP: Beware of excessive use imposed by Google. Currently you are limited to 20,000-50,000 URL lookups per day. See https://docs.google.com/macros/dashboard for UrlFetch specifically.
//TIP: To avoid excessive usage, after running a set of ISSNs, copy and paste over the discovered values by going to Edit -> Paste special -> Paste values only
