I'll take my flyer at simple answers.
>001 and 010
001 is the control number in the system from which the record came.
003 names that system.
010 is the control number at the Library of Congress, often printed in
books, and like the 020 ISBN used as an an access point. In the LC
catalogue, it is used as their 001.
If you change the 001, and it is not the same as the 010, the old 001
goes in 035 with whose number it was from 003 in curves.
An item not catalogued by LC has no 010. Some libraries use the LC
LCCN (if one) as their own 001; some use OCLC's numbers; most use
their own inhouse numbering. Think of it as being like an accession
number used to file your record .
>For series statement-which tag we'll use=2C either 440 or 490? Why?
440 is obsolete and should not be used.
Formerly, 440 was the series on the item when it was the same as the
traced form of the series. Now the form on the item is in 490 1, and
the traced form is in 830 (unless in counterproductive 800$t, 810$t,
or 811$t ), even if the two are identical. 490 1st indicator 1 now
means traced in 8XX, not traced differently.
