Members listed in new DirectoryThe attached Membership Directory for

1988-1991 lists 2528 MSA members for1988. This is one of the largest membershipdirectories ever published by the Society.The Directory features an alphabetical listingof all members giving membership type, joindate, and main and secondary interest areas inaddition to address and telephone numbers.

The Directory includes 1770 dues-payingmembers and fellows, 412 students, 10spouses, 310 life members and fellows, 20associated life members and fellows, and 6honorary fellows.

Interest areas vary widely. Mineralogy wasthe choice of 24% of the members listed,followed by Geochemistry and MetamorphicPetrology each with 11%, Igneous Petrologywith 10%, Crystallography/CrystalChemistry 9%, Economic Geology 8%,Phase Equilibrium 4%, Clay Mineralogy 4%,and Sedimentary Petrology 1%. Two percentindicated another area of interest, while nointerest area was available for 15% of theindividuals listed.

Approximately 1800 cards were returnedby the membership updating address and

telephone information and providing birthdate, highest degree earned, and theinstitution where that degree was earned. Ofthe members listed, 42% have either a Ph.D.or Doctor of Science degree.

The Directory was produced directly fromcomputer files at the MSA Business Office.The address and telephone number(s) forindividuals who did not return the directorycard were taken from the computer andprevious membership directory. Telephonenumbers were used if the area code matchedthe address city and state.

Words and names with more than onecapital letter will have a space before thesecond capital letter, i.e., Mc Andrew. Thecomputer requires this space in order to printthe second capital letter. Foreign phonenumbers have a hyphen following thenumbers placed in the ( ) on the directorycards.

Care has been taken to proofread thenames and addresses in this list. However, ifyour name or other information is incorrect,please write to the MSA Business Office withthe correct information.

Vital contributions made by abstractors

Access to publications across the broadrange of mineralogical sciences is increasinglybeing achieved through computerizedreference systems which can identify andretrieve the contents of thousands of journalsby key words, by author, or by combinationsof these and other factors. The MineralogicalSociety of Great Britain and theMineralogical Society of America jointlypublish Mineralogical Abstracts, and havecollaborated for years to cover as many of thehost of relevant journals as possible,principally through the services of volunteerabstractors. Many abstracts prepared by theauthors themselves are inadequate; they maybe toO complete, incomplete, or ininappropriate formats for publication. Thus,abstractors make valuable contributions toour science by using their technical expertiseto bring the contents of diverse researchpapers into Mineralogical Abstracts, which isnow part of the computerized GeoAbstractsdata reference service, DW.oG file 292.

Abstractors have commonly not receivedthe recognition and appreciation theydeserve from their professional colleagues.On behalf of this Society, Iwould like tooffer my warmest thanks to each and everyabstractor. I also want to record myappreciation to the employers of abstractors,who pay the salaries and operating expensesfor many abstractors. I would like also tospecially thank the people involved with theproduction of Mineralogical Abstracts from itslong-time Principal Editor, Professor R. A.Howie, through all the associated editors andthe persons responsible for the literaturefrom specific countries and subjects. Special

21The Lattice

thanks are also due to Professor Karl A.Riggs of Mississippi State University for hisyears of effort to organize abstractors inAmerica.

Many wish to volunteer to serve MSA.Would you be willing to serve by becomingan abstractor? Usually an abstractor coversone or, at most, a few journals in a topic inwhich they have expertise. Currently, anabstractor is needed for Soviet Physics-Crystallography. Other journals become"available" from time to time. Please contactProfessor Riggs at (601) 325-2910 or by mailif you can help.

MSA Council has twice declined to publisha decennial index to the AmericanMineralogist. The principal reasons are thelarge cost involved, and the increasingperception that computerized referenceservices adequately fulfill the needs of manyscientists. Council recognizes that computersystems are not available everywhere, butnotes that most libraries with collections ofresearch journals also have access tocomputerized reference services. It is implicitin these arguments that abstractors will havecovered each journal and entered anappropriate abstract into the computer files!Thus, the vital contributions of abstractors totheir profession must be fully appreciated byall.

Sincerely,

David B. Stewart1988 President

THIS IS A MEETING AT A SPECIALPLACE WITH SPECIAL PLANS FORYOU. WE INVITE YOU TO ATTEND-PREPARE NOW FOR THAT rrONCE-IN-A-CENTURY TRIP"/

Denver is situated where the vast Interior Plainsof the United States meet the spectacular FrontRanges of the Rocky Mountains. It provides oneof the most varied geologic settings of anymajor American city and is an extraordinarylocation in which to celebrate GSA's lOOth year.

The topographic and structural basin beneaththe city is an important source of hydrocarbonsin the Rocky Mountain foreland region. TheFront Ranges to the west are characterized bycolorful upper Paleozoic sedimentary rocks,which bring tourists to the Garden of the Godsand to the Red Rocks Amphitheater, and by thehistorical mining districts in the Precambrianigneous and metamorphic rocks of the ColoradoMineral Belt. The ranges also mark the easternedge of the geologically complex Cordilleranmountain system that extends from Alaska toTierra del Fuego.

In addition to their mineral wealth, themountains to the west provide a dramaticgeologic display that you will not want to miss.This is indeed a special place for a special year.

CENTENNIALOPENINGCEREMONIES ANDMEGA SYMPOSIUMThe Centennial Opening Ceremonies willlead off the Centennial Celebration onMonday morning, just prior to the GeneralSession. The ceremonies will be a tributeto GSA and to the science of geology.

Centennial General SessionOn Monday morning, October 31, after theOpening Ceremonies, the Opening GeneralSession will be "North America in 4-0."This megasymposium, unopposed by anyother session, will be convened byAlbert W. Bally, GSA President.

TECHNICALPROGRAMCALL FOR PAPERSABSTRACTS DEADLINE FORSYMPOSIA ANDVOLUNTEERED PAPERSFRIDAY, JUNE 10, 1988Technical sessions consist of bothvolunteered and invited papers, organizedin one of four presentation formats: invitedsymposia, open symposia, theme sessions,and discipline sessions. The formats aredistinguished by the mix of invited andvolunteered papers. In invited symposia, allspeakers are invited by the conveners.Open symposia have both invited andvolunteered components; volunteercontributors must contact the convenerabout submitting an abstract. If a paper isnot accepted for an open symposium, it willbe considered for a discipline sessionalong with regular volunteered abstracts.Theme sessions have no invited speakersbut are organized around specific topicslisted on the 1988 abstract form. If anabstract is submitted to, but not acceptedfor, a theme session, it will continuethrough the evaluation process to beconsidered for the appropriate disciplinesession. Discipline sessions are organizedfrom volunteered abstracts submitted toGSA on a general basis arid assigned toone of 34 discipline classifications.

After review, selection of volunteeredpapers for presentation in theme ordiscipline sessions is made by members ofthe Joint Technical Program Committee(JTPC). Each discipline has a representa-tive on the JTPC, appointed by either aGSA Division or an Associated Society.

May, i988

Theme session organizers will be desig-nated either by the sponsoring Division or\ssociated Society or by the TechnicalProgram Committee chairmen.

OPEN SYMPOSIAPROCEDURE

• Authors interested in volunteering anabstract for an open symposium mustcontact the convener by May 1 to besure that the abstract will be consistentwith the mission of the symposium.

• If agreed upon with the convener, theauthor will submit the abstract directlyto the convener by June 10. The paperthen will be reviewed with the otherabstracts submitted for the symposium.

• After review, abstracts not selected bythe convener for inclusion in thesymposium will be automaticallysubmitted for consideration asvolunteered papers.
