Dear Koha community I have recently started to examine Koha and immediatelly face a couple of problems.   Firstly, I try to place a hold on an item the Koha prevents me of ding it and displays a message, namely Cannot Place Hold Too Many Holds: Haik Zargarian has too many holds. No copies are available to be placed on hold In fact, Haik Zargarian (fictive patron) has no holds on his account and there are sevreal available items for this record. Secondly, when I import a Marc-record in Koha it does not show the authors name and simply ignores the fact, that I have properly indicated the data in the "Personal name" section of this field 100 ?   - MAIN ENTRY--PERSONAL NAME −.   Furthermore, when I access an existing record Koha diplays its author's name. However, when I enter the "Edit" section and save the record without changing even a letter, the author's name evaporates and I see a data like this Additional Authors: Williams, Richard S., Iceland--Orkustofnun Series: U. S. Geological Survey Professional paper ; . No. 1746 Published by: U.S. Department of the Interior/U.S. Geological Survey, (Reston, Va. :) Description: x, 225 p. : ill. (chiefly col.), maps ; 28 cm.   Please, any comments or explanations.   Thanks in advance
