Just another followup for everyone.
We have also created SVG versions of the libraries (zip & sit) for those users having problems with the eps version. Some graphics packages, especially on the Linux platform seem to have problems with the Illustrator eps format, but the SVG should work fine.
I have also just created a zip package containing the full set of our symbol libraries in Illustrator legacy eps v3 format. This format should work on all versions of Illustrator from 3 onwards, and I assume many other older vector packages which support the eps format. The problem with this version is, however, that many of the more complicated symbols which utilize gradients and other effects are either blank or incomplete. Many other symbols are now made up of lines in an attempt to duplicate the effect of the gradient. Unfortunately this is simply an artefact of this old eps format. I was going to provide this as a download option on our website, but given the poor quality of many of the symbols I have decided against that option.
If there are users who would like a copy of this version in either zip or sit archive format, please let me know and I will send you the link. Please make sure you are already registered for the Symbol Libraries via our website at
http://ian.umces.edu/symbols.
However, I would definitely suggest that users upgrade to at least Illustrator 9 (preferably 10 or CS so you will have full support for the symbol palette functions) to enable access to the full quality version of the IAN Symbol Libraries, rather than this low quality legacy version.
