Young & P.R. Bown INA Newsletter 15/1, 1993 - Salamanca Abstracts 41 EDITORS NOTES AND ACKNOWLEDGEMENTS The abstracts are not exactly as submitted since this volume was mainly produced via a Kurzweil text scanner - which converted the heterogeneous original copy into word processor files. The accuracy of scanning is dependant on the print quality of the originals and despite checking it is inevitable that some errors will have been introduced. Accents are a special problem, since they have to be individ ually re-inserted, and some will have been lost We have made corrections to spelling (including standardisation to UK spelling) - and to grammar where there were obvious problems with English usage. There has, however, been no scientific editing or vetting of the abstracts, other than removal \other nomina nuda. Some addresses have been shortened to save space, full postal addresses can be found in the INA Membership directory (INA Newsletter 14/3, p.118-124) The format adopted is virtually the same as for the Prague Abstract volume (INA Newsletter 13/2, 1991), including the use of topic codes similar to those used in the INA Bibliographies. These codes are (1) Age range covered. (2) Geographical provenance of studied material. (3) General topic of paper, N.B. Biostratigraphy - applied biostratigraphic study. Zonation - development of zonation scheme. (4) Particular feature of the abstract. We are very grateful to the co-operative set of authors who sent abstracts byE-mail or on disk, and to most authors for submitting their abstracts on or near the dealine and for closely observing the reference format, etc. Jeremy R.
