Dear colleagues, especially from the Netherlands, I've tried in vain to get my hands on two short articles published in De Kreukel. They are not available through interlibrary loan here in Germany: Maassen, W.J.M., 1985: Eerste aanvulling op "Bibliographia Malacofaunae Jugoslaviae". - De Kreukel 21 (10), 145-148. Maassen, W.J.M., 1989: Tweede aanvulling op "Bibliographia Malacofaunae Jugoslaviae". - De Kreukel 25 (4), 75-78. Is there any kind soul out there who can provide me with a copy (xerox or electronic - as you like) of these 8 pages? Or does anybody know the address of the author, Mr. W. J. M. Maassen? Thank you very much for any help! Wolfgang Neun Hessenstrasse 66 D-97078 Wuerzburg Germany Email: [log in to unmask] PS. I've already got the original work "Bibliographia M. J." and the "Derde aanvulling ..." PPS. Of course you may charge me with any expenses.
