Hi Floyd!
One approach would be to use SRS, Thure Etzolds fabulous Sequence
Retrieval System (www.ebi.ac.uk -> Services -> SRS).
Start a new SRS session, select the EMBL database, query the FtKey field
for the value "intron" (where "intron" is part of the controlled
vocabulary for features, if I'm right). This will give you a set of the
many (26416 when I tried it) EMBL sequence entries that have annotation
regarding introns. Now you can look at one entry at a time and click on
the intron-link(s) for each entry...
hope this helps,
gerald
