I. The printed version


During the past three years the editing of IBVS went on its way without any serious complication. After a short (half year long) period, when L. Szabados and J. Jurcsik served together as scientific editors, László retired and Johanna took over the editorship (beside K. Oláh). Taking seriously his new position as advisor, László still checks all issues before print (finding our mistakes all the time), and we would like to thank him this service very much expressing our hope that he will continue to help us.

As it is well seen from Fig. 1., the number of printed issues strongly fluctuated during the last three years. The fast growth of the yearly issues was very probably due to the spread of the CCD cameras in small observatories and among amateur astronomers which resulted in the fast growth of newly discovered variables. Since the beginning of the mass photometry of various projects catalogizing of the new variables is a serious and still unsolved problem (as we discussed in the Manchester GA). Thus we decided, that new discoveries should be submitted in collected form, i.e., the authors should put as much new variables as possible into 4 pages. Still, the question arises, if it has any scientific importance of discovering e.g. 8 new W UMa stars between 14-16 magnitudes, and is it really important to publish those data?

Of course all those discoveries that have some astrophysical importance, are always welcome (e.g. bright stars that were not known as variables etc.).

New light curves of known variables that are made in one color, or without any filter (CCD R!) are also accepted in collected form. Only multicolor light curves with analysis could be accepted on a single object.

Similar is the situation with the times of minima of eclipsing binaries. We stress the importance of publishing these results, but we ask the authors to collect their minima times and submit them together e.g. once or twice a year.

Fig. 2. shows the fluctuations of the issues/year and the printed pages/year since 1995 to the present. This figure shows, that while the number of issues decreased and in 2002 was about the same as in 1995, we printed 100 pages more. This follows from introducing the collected form of publications: less number of issues but more results.

All authors are adviced to attach their data to the publication, and a lot of them do so, when they notice that this way their data would be stored for the future. We also asked the authors of the past issues back to the beginnings to send us their datafiles and indeed, many of them sent us the data.

Since about a year ADS lists IBVS among the refereed publications. Indeed, we put a lot of effort for the refereeing with the help of many external referees, who help us a lot. Most of them make the report within a few days, that is necessary for an express journal like IBVS.

Reading the literature we meet IBVS all the time in the references sections of various journals. Table 1 shows the citations/issue numbers of our papers from 1990 till the present. We plan to ask for listing in the Science Citation Index.

Editorial Board

During the last three years the Editorial Board of IBVS was the following:

  • H. Duerbeck
  • G. Handler
  • D. Kurtz (chair)
  • C. Maceroni
  • S.S. Saar
  • D. Sasselov
  • B. Skiff

and ex-officio members: E. Guinan (Div. V.), J. Christensen-Dalsgaard (Comm. 27.), P. Szkody (Comm. 42.).

Advisors: P. Harmanec, N.N. Samus, C. Sterken, L. Szabados

We would like to thank them for their help and support during the past three years.

As H. Duerbeck, D. Kurtz and C. Maceroni served 6 years a Board members, they will retire, and the Board will vote for new members. Our suggestions for future Board members are:

  • B. Gänsicke
  • M. Schreiber
  • L.L. Kiss

Suggestions are welcome.


II. The electronic IBVS

Drawing inspiration from the STELAR project, the electronic IBVS was conceived in 1993, and made its debut at the General Assembly in The Hague (in 1994). By 1996 archive (scanned) issues had become available on the Internet. Computer-typeset issues have been offered in HTML format from 2000, and scanned issues are served with figures in HTML format by the Sydney General Assembly.

There is a choice of different formats: the PostScript is an identical representation of the refereed printed paper; the HTML, which has richer features but, as it is created automatically, it could be different from the authentic PS version, the differences, however, are only formal; and finally the source, which is ASCII for the archive issues (produced by an Optical Character Recognition program, and therefore might contain errors), and LaTeX for the issues produced after August, 1994.

The PostScript versions are made available on CD-ROMs: Konkoly Obs. has published two CDs with issues 1-4000 (2000) and 4001-5000 (2001), and the issues of the JAD regularly contain a few volumes of the Bulletin.

Cooperation with the ADS and CDS enables cross-linking IBVS with the ADS Abstract Service and SIMBAD. The software for the production of HTML version of the papers was developed with the help of the CDS.

The present activities concerning the electronic IBVS include the development of tools which the authors can use for checking and/or submitting their manuscripts, and setting up a database-like service, which uses the material published in IBVS. This new service is intended to serve specific data like i.) finding charts, ii.) comparison stars, iii.) auxiliary data files (mostly photometry), iv.) light curves, v.) ephemerides, vi.) O-C curves, and maybe even vii.) minima times. This new service will respond to standard Astronomical Server URL queries, and will be Virtual Observatory enabled.
