%  The Stanford Linear Accelerator Center SPIRES-HEP database has been          
%  comprehensively cataloguing the High Energy Particle Physics (HEP) literature
%  online since 1974, and indexes more than 500,000 high-energy physics related 
%  articles including their full citation tree.                                 
%  The network contains a citation graph of the hep-th portion of the arXiv.    
%  The units names are the arXiv IDs of papers; the relation is  X cites Y .    
%  Note that revised papers may have updated citations. As such, citations may  
%  refer to future papers, i.e. a paper may cite another paper that was publishe
%  after the first paper.

%  The SLAC/SPIRES dates for all hep-th papers are given. Some older papers were
%  uploaded years after their intial publication and the arXiv submission date  
%  from the abstracts may not correspond to the publication date. An alternative
%  date has been provided from SLAC/SPIRES that may be a better estimate        
%  for the initial publication of these old papers.
