In the early years, my research was in traditional taxonomy - revisions and new taxa primarily of scorpionfishes, stonefishes and their allies. I began on Atlantic groups, then moved to the Indo-Pacific groups. These revisions continued while I spent about 8 years in administration, ending as Director of Research. In the early 1980s, I decided to “organize the information of ichthyology” as I called it. An NSF proposal received mixed reviews - with some thinking it could not be done - but with computers becoming increasingly powerful, I knew I could do it. That first grant request was partially funded, and this started me on an exciting period of my new life. The importance can be summarized in that I did a “little bit of every ichthyologist’s research” - tracking down nearly all original descriptions, building a database of all available names in fishes, going to many collections gathering information on types, solving nomenclatural issues and assisting ichthyologists with inquiries.

Note that when Drs. Paxton, Allen, Randall and many others and I began our careers, we had pencils and 3x5 cards. It would take months just to assemble the species and genera names and references one needed for a revision. Now that can be done in less than an hour - a download of all pertinent taxa, references, information on type specimens, full citations to original descriptions, and a guide to recent literature.

The first volume of the Catalog of Fishes, treating the genera, was published in 1990. This was followed in 1998 by publication of all genera, species, and original literature. Regular online editions have been posted continuously since 1998 with technical support from the California Academy of Sciences.

I continue to work on the database nearly daily, with more assistance from NSF, expansion of coverage, and addition of hundreds of “status” references. I have had complete support and freedom to work on this project for the last half of my career at CAS. I went off salary in 2004, with funds for supplies and travel coming from the California Academy of Sciences and some other sources. Recently, Ron Fricke has joined me as a partner - with Ron concentrating on early literature and translations - and he has worked on new databases added at the end of 2008 (museum collections and full citations for 2400 journals containing ichthyological articles).

Of course, I thought the new fish taxa would drop off, but the opposite has happened. New species in 2008 numbered over 500. The taxonomic publications today are the best ever, with good descriptions, consistent spellings of taxa and authors' names, up-to-date literature and wonderful photography. Much of that excellence and consistency I believe is the result of the Catalog of Fishes database, probably the most accurate for any major taxonomic group. Into the early 1900s, the number of authors describing new species in a year was about 50; now hundreds of enthusiastic workers per year have the experience of describing new fish taxa and contributing to our knowledge of fishes. It is an interesting time for us all, and I look forward to receiving pdfs weekly.

My health is good, and I am as enthusiastic as ever to continue the Catalog of Fishes project. I have CAS funding for expenses for 2009 and 2010. Most ichthyologists use the database, and I believe this has made us more efficient and more accurate, probably more so than in any other fairly large taxonomic discipline.
