A Catalog of Variable Stars based on the new name list
We present a new electronic version of the General Catalog of VariableStars (GCVS) based on the new IAU name list of confirmed variable stars.The catalog contains 1270 stars, most of them contained earlier in theNew Catalog of Suspected Variable Stars or its supplement. A number ofrecent studies—including those by authors of the catalog, whoinvestigated many stars using data from modern automatic surveys,determined light-curve elements for periodic stars, and plotted numerouslight curves—have made it possible to move these stars to theGCVS. Among the catalog objects, 24 stars are novae or other unusualvariable stars that acquired their GCVS names out of the usual order,upon communication from the Bureau of Astronomical Telegrams of theInternational Astronomical Union. We present the GCVS names,coordinates, classifications (in two forms: the GCVS system and a new,proposed system), brightness-variation limits, and light-curve elementsfor the catalog stars, as well as bibliographic references and remarkswhen necessary. We discuss several catalog stars that are ofastrophysical interest or caused problems during the compilation of thecatalog.

A new catalogue of eclipsing binary stars with eccentric orbits
A new catalogue of eclipsing binary stars with eccentric orbits ispresented. The catalogue lists the physical parameters (includingapsidal motion parameters) of 124 eclipsing binaries with eccentricorbits. In addition, the catalogue also contains a list of 150 candidatesystems, about which not much is known at present.Full version of the catalogue is available online (see the SupplementaryMaterial section at the end of this paper) and in electronic form at theCDS via http://cdsarc.u-strasbg.fr (130.79.128.5) or viahttp://cdsweb.u-strasbg.fr/cgi-bin/qcat?J/MNRAS/(vol)/ (page)E-mail: ibulut@comu.edu.tr
