Yes.
The software on the EMBL CD-ROM allows searching by entryname, accession
number, authors, journal citation, feature key, database cross-references,
*free text* including keywords, and date. A query is entered into a
screen form. Boolean operators AND/OR/NOT operate within fields, and an
implicit AND operates between fields. For all the text fields, an index of terms
can be browsed and selected from (eg list of journal abbreviations).
Sequence length is actually not something we currently index.

It's not so easy to convey its full beauty in words, but we have some
'spare' free CD's from past releases that you can try. Just supply
postal address if you want one.

I would add that we do not see our CD-ROM or software as a rival to
Hitachi, GCG et al. The software allows the user to find and extract data
from the EMBL and SWISS-PROT databases. For further analysis of this data,
other packages exist. (The CD-ROM can also be used for FASTA searches quite
effectively).
