• Fix for ReadPDFs when when reading one file which is a JSTOR pdf

Changes in Version 0.8.52 (2015-01-26)

NEW FEATURES

• ReadGS fixed to account for changes to Google "API" (h/t Norman L Guinasso Jr).
• Improved parsing for BibTeX format names ending with a '}' (h/t Henrik Bengtsson).
• Printing references with style = "html" would not always add an opening tag when bib.style = "numeric" or bib.style = "alphabetic" (h/t Henrik Bengtsson).
• format.BibEntry would ignore the .style argument if called directly by the user. Note, this function should normally not need to be called directly. (h/t Henrik Bengtsson)

NEW FEATURES

• Improved formatting of citation given to CrossRef for increased chances of finding matches with GetDOIs function (h/t Erich Studerus)
• Additional parsing of 'month' field to accomodate days and ranges of days and months. Example bib entries that will be parsed correctly include month = jun # "/" # jul, month = "20~" # jan, month = "20--25~" # dec, month = "10~" # jan # "/" # feb (request of Stephen Eglen)

• Abstracts returned by NCBI Entrez can be multiple parts. This is now handled correctly and the complete abstract will be returned in the 'abstract' field. (h/t Erich Studerus)
• DOI's were too naively extracted from NCBI Entrez results, resulting in some entries having 'doi' fields with length greater than one. Now fixed. (h/t Erich Studerus)
