The ISSN-L table from issn.org works fine, or you may use the free 
service from the german EZB:

A fairly easy task normally, except for one glaring issue -- the unique key for these tables, the ISSNs, don't match.

To rectify this, we have two options -- either we can hand edit one of the sources to use the other type of ISSN (a HUGE undertaking), or (and hopefully) if there existed some resource that mapped print ISSNs to electronic ISSNs (ala an OCLC Authority database but for ISSNs), we could use this to map between the ISSN types.  Obviously, we prefer the latter.
