020 ISBN: should match
The International Standard Book Number (known as and ISBN) is a unique number placed on a book so that it can be easily identified. There are two types of ISBNs: a ten digit ISBN and a 13 digit ISBN. Often the record will contain the ISBN numbers for different formats of the book, such as hardback, paperback, and/or an eBook. This is fine; all of these should be kept. The ISBN is usually found on the title page (t.p.) or the t.p. verso, colophon, back cover, or back of dust jacket. Sometimes the number on the book will not match the ISBN stated on the record, or sometimes the 020 ISBN may be in a z subfield, meaning that the ISBN is obsolete and no longer used. If the book otherwise matches the record, simply scan or type in the missing ISBN in a 020.

040 Cataloging Source
The 040 field is designated for providing the name of the organization(s) that created the original record, assigned MARC content designation and transcribed the record into machine-readable form or modified an existing MARC record. Every agency that creates records has a designated 3 letter code, which is identified in subfield a. A 3 letter language code, used in subfield b, is used to specify the language in which the material is cataloged, if there is no “ǂb eng” then add it. Subfield c shows the agency that input the record into a shared cataloging system. The same 3 letter code assigned to agencies is used and is usually the same agency that created the record. The most common agency code you will see is DLC (which is the Library of Congress). The most important thing to know about this field is that it is different in AACR2 than it is in RDA (a subfield e = “rda” must be used to show that RDA rules were used to create the record. So, if the record is RDA and there is a 040 without the subfield e of “rda” it needs to be added.

041 Language Field
This field indicates the language of the item when the fixed field does not give enough information. Accordingly, this field is only used if more information is needed for the patron to completely understand the nature of the item with regards to language. For example, this field is used if the item is a translation or includes a translation. This field is also used if the item contains text written in more than one language. The language the text is written in is entered into a subfield a. Each subsequent language should be entered into additional a subfields. The original language the item was translated from is entered in a subfield h. There is no punctuation between subfields, or following the abbreviations used to identify languages.

049 Collection code, number of volumes/copies
The 049 field is used to indicate the specific collection where the book is located and to indicate what volumes or how many copies of the item we hold at the library.
...
*For multi-volume sets: Acquisitions may create an order item for each volume (if so, transfer and attach all the order records to the same bibliographic record after copy cataloging), AND/OR there may already be a full bibliographic record in Sierra (if so, just create a new item for the volume which needs to be added into the system and change the 049 field to reflect what the library holds).
050/090 Call Number
Call numbers are made up of a Classification number that is assigned according to the subject contents of the item, along with one or two “cutters” and the date of publication. Library of Congress Classification Numbers include one or two letters indicating the subject accompanied by numbers. The classification number and the first cutter number, if there are two, are entered in subfield a, while the second cutter and the date are entered in subfield b. If there is only one cutter number the classification number is entered in subfield a, and the cutter number and the date are entered in subfield b. *There should always be a period at the beginning of the first cutter.
