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!

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.
